Vaccines

After more than 5 decades of trying, the drug industry is on the verge of providing effective immunizations against the respiratory syncytial virus (RSV), which has put an estimated 90,000 U.S. infants and small children in the hospital since the start of October.

But only one of the shots is designed to be given to babies, and a glitch in congressional language may make it difficult to allow children from low-income families to get it as readily as the well insured.

Since 1994, routine vaccination has been a childhood entitlement under the Vaccines for Children program, through which the federal government buys millions of vaccines and provides them free through pediatricians and clinics to children who are uninsured, underinsured, or on Medicaid – more than half of all American kids.

The 1993 law creating the program didn’t specifically include antibody shots, which were used only as rare emergency therapy at the time the bill was written.

But the first medication of its kind likely to be available to babies, called nirsevimab (it was approved in Europe in December, and Food and Drug Administration approval is expected in the summer of 2023), is not a vaccine but rather a monoclonal antibody that neutralizes RSV in the bloodstream.

The Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices is certain to recommend giving the antibody to infants, said Kelly Moore, MD, president of the advocacy group Immunize.org. The CDC is currently assessing whether nirsevimab would be eligible for the Vaccines for Children program, agency spokesperson Kristen Nordlund told KHN.

Failing to do so would “consign thousands upon thousands of infants to hospitalization and serious illness for semantic reasons despite existence of an immunization that functionally performs just like a seasonal vaccine,” Dr. Moore said.

Officials from Sanofi, which is producing the nirsevimab injection along with AstraZeneca, declined to state a price but said the range would be similar to that of a pediatric vaccine course. The CDC pays about $650 for the most expensive routine vaccine, the four shots against pneumococcal infection. In other words, FDA approval would make nirsevimab a blockbuster drug worth billions annually if it’s given to a large share of the 3.7 million or so children born in the U.S. each year.

Pfizer and GlaxoSmithKline are making traditional vaccines against RSV and expect FDA approval later in 2023. Pfizer’s shot initially would be given to pregnant women – to shield their babies from the disease – while GSK’s would be given to the elderly.

Vaccines designed for infants are in the pipeline, but some experts are still nervous about them. A 1966 RSV vaccine trial failed spectacularly, killing two toddlers, and immunologists aren’t totally in agreement over the cause, said Barney Graham, MD, PhD, the retired National Institutes of Health scientist whose studies of the episode contributed to successful COVID-19 and RSV vaccines.

After 2 years of COVID lockdowns and masking slowed its transmission, RSV exploded across the United States in 2023, swamping pediatric intensive care units.

Sanofi and AstraZeneca hope to have nirsevimab approved by the FDA, recommended by the CDC, and deployed nationwide by fall to prevent future RSV epidemics.

Their product is designed to be provided before a baby’s first winter RSV season. In clinical trials, the antibodies provided up to 5 months of protection. Most children wouldn’t need a second dose because the virus is not a mortal danger to healthy kids over a year old, said Jon Heinrichs, a senior member of Sanofi’s vaccines division.

If the antibody treatment is not accepted for the Vaccines for Children program, that will limit access to the shot for the uninsured and those on Medicaid, the majority of whom represent racial or ethnic minorities, Dr. Moore said. The drugmakers would have to negotiate with each state’s Medicaid program to get it on their formularies.

Excluding the shot from Vaccines for Children “would only worsen existing health disparities,” said Sean O’Leary, MD, a professor of pediatrics at the University of Colorado at Denver, Aurora, and chair of the infectious diseases committee of the American Academy of Pediatrics.

RSV affects babies of all social classes but tends to hit poor, crowded households hardest, said Dr. Graham. “Family history of asthma or allergy makes it worse,” he said, and premature babies are also at higher risk.

While 2%-3% of U.S. infants are hospitalized with RSV each year, only a few hundred don’t survive. But as many as 10,000 people 65 and older perish because of an infection every year, and a little-discussed legal change will make RSV and other vaccines more available to this group.

A section of the 2022 Inflation Reduction Act that went into effect Jan. 1 ends out-of-pocket payments for all vaccines by Medicare patients – including RSV vaccines, if they are licensed for this group.

Before, “if you hadn’t met your deductible, it could be very expensive,” said Leonard Friedland, MD, vice president for scientific affairs and public health in GSK’s vaccines division, which also makes shingles and combination tetanus-diphtheria-whooping cough boosters covered by the new law. “It’s a tremendously important advance.”

Of course, high levels of vaccine hesitancy are likely to blunt uptake of the shots regardless of who pays, said Jennifer Reich, a sociologist at the University of Colorado who studies vaccination attitudes.

New types of shots, like the Sanofi-AstraZeneca antibodies, often alarm parents, and Pfizer’s shot for pregnant women is likely to push fear buttons as well, she said.

Public health officials “don’t seem very savvy about how to get ahead” of claims that vaccines undermine fertility or otherwise harm people, said Ms. Reich.

On the other hand, this winter’s RSV epidemic will be persuasive to many parents, said Heidi Larson, leader of the Vaccine Confidence Project and a professor of anthropology at the London School of Hygiene and Tropical Medicine.

“It’s a scary thing to have your kid hospitalized with RSV,” she said.

While unfortunate, “the high number of children who died or were admitted to the ICU in the past season with RSV – in some ways that’s helpful,” said Laura Riley, MD, chair of obstetrics and gynecology at Weill Cornell Medicine, New York.

Specialists in her field haven’t really started talking about how to communicate with women about the vaccine, said Dr. Riley, who chairs the immunization group at the American College of Obstetricians and Gynecologists.

“Everyone’s been waiting to see if it gets approved,” she said. “The education has to start soon, but it’s hard to roll out education before you roll out the shot.”

New surveillance data from the Vaccine Adverse Event Reporting System (VAERS) back previous findings of increased risk for Guillain-Barré syndrome (GBS) after receiving the Janssen COVID-19 vaccine (Ad26.COV2.S).

Over 14 months, GBS reporting rates within 21 and 42 days of administration of Janssen’s replication-incompetent adenoviral vector vaccine were approximately 9 to 12 times higher than after administration of the Pfizer-BioNTech (BNT162b2) or the Moderna (mRNA-1273) mRNA COVID vaccines.

Additionally, observed GBS cases after the Janssen shot were 2 to 3 times greater than expected, based on background rates within 21 and 42 days of vaccination.

Conversely, and confirming prior data, there was no increased risk for GBS with the Pfizer or Moderna vaccines and no significant difference between observed and expected numbers of GBS cases after either mRNA COVID-19 vaccine.

The findings were published online  in JAMA Network Open.
 

More precise risk estimates

Winston Abara, MD, with the U.S. Centers for Disease Control and Prevention, and colleagues analyzed GBS reports submitted to the VAERS between December 2020 and January 2022. 

Among 487.6 million COVID-19 vaccine doses administered, 3.7% were Janssen’s Ad26.COV2.S vaccine, 54.7% were Pfizer’s BNT162b2 vaccine, and 41.6% were Moderna’s mRNA-1273 vaccine.

There were 295 verified reports of GBS identified after COVID-19 vaccination. Of these, 209 occurred within 21 days of vaccination and 253 within 42 days.

Within 21 days of vaccination, GBS reporting rates per 1 million doses were 3.29 for the Janssen vaccine versus 0.29 and 0.35 for the Pfizer and Moderna vaccines, respectively. Within 42 days of vaccination, reporting rates per 1 million doses were 4.07, 0.34, and 0.44, respectively.

Also within 21 days of vaccination, GBS reporting rates were significantly higher with the Janssen vaccine than the Pfizer vaccine (reporting rate ratio, 11.40) and the Moderna vaccine (RRR, 9.26). Similar findings were observed within 42 days after vaccination.

The observed-to-expected ratios were 3.79 for 21-day and 2.34 for 42-day intervals after receipt of the Janssen vaccine, and less than 1 (not significant) after the Pfizer or Moderna vaccine within both post-vaccination periods.

“Unlike prior studies, our analysis included all U.S. reports of verified GBS cases that met the Brighton Collaboration GBS case definition criteria (Brighton Levels 1, 2, and 3) submitted over a 14-month surveillance period to the to the Vaccine Adverse Event Reporting System,” Dr. Abara said in an interview. “Because we used all U.S. reports, the sample of verified GBS cases in this analysis is larger than other studies. Therefore, it may provide a more precise estimate of the GBS risk within 21 and 42 days after mRNA and Ad26.COV2.S vaccination,” he said.
 

‘Remarkably low’ use

Nicola Klein, MD, PhD, Kaiser Permanente Vaccine Study Center, Oakland, Calif., noted that this is a “nice confirmatory analysis that supports and further expands what’s been observed before.”

Last year, as reported by this news organization, Dr. Klein and colleagues reported data from the Vaccine Safety Datalink confirming a small but statistically significant increased risk for GBS in the 3 weeks after receipt of the Janssen COVID-19 vaccine but not the Pfizer or Moderna vaccines.

Unlike VAERS, the Vaccine Safety Datalink is not a reporting system. It’s an active surveillance of medical records in the Kaiser Permanente system. The VAERS is a passive system, so it requires individuals to report GBS cases to the VAERS team, Dr. Klein explained.

So although the two studies are slightly different, overall, the VAERS data is “consistent with what we found,” she said.

Also weighing in, C. Buddy Creech, MD, MPH, director of the Vanderbilt Vaccine Research Program and professor of pediatrics at the Vanderbilt University School of Medicine, Nashville, Tenn., said it is “important to realize that GBS had been observed after adenovirus-vectored vaccines earlier in the pandemic, both for the AstraZeneca vaccine and the Janssen vaccine.”

The Advisory Committee on Immunization Practices (ACIP) preferentially recommends that people age 18 years and older receive an mRNA COVID-19 vaccine rather than the Janssen adenoviral vector vaccine when both types of COVID-19 vaccine are available.

“Thus, the use of the Janssen vaccine is remarkably low in the U.S. right now,” Dr. Creech said.

“Nevertheless, we have a firm commitment, both scientifically and ethically, to track potential side effects after vaccination and to make sure that the vaccines in use for COVID, and other important infectious diseases, are safe and effective,” he added.

The study had no commercial funding. Dr. Abara and Dr. Creech have reported no relevant financial relationships. Dr. Klein reported having received grants from Pfizer research support for a COVID vaccine clinical trial, as well as grants from Merck, GlaxoSmithKline, Sanofi Pasteur, and Protein Science (now Sanofi Pasteur).

Buddy Creech, MD, MPH, director of the Vanderbilt Vaccine Research Program and professor of pediatrics at the Vanderbilt University School of Medicine, Nashville, Tenn., said it is “important to realize that GBS had been observed after adenovirus-vectored vaccines earlier in the pandemic, both for the AstraZeneca vaccine and the Janssen vaccine.”

The Advisory Committee on Immunization Practices (ACIP) preferentially recommends that people age 18 years and older receive an mRNA COVID-19 vaccine rather than the Janssen adenoviral vector vaccine when both types of COVID-19 vaccine are available.

“Thus, the use of the Janssen vaccine is remarkably low in the U.S. right now,” Dr. Creech said.

“Nevertheless, we have a firm commitment, both scientifically and ethically, to track potential side effects after vaccination and to make sure that the vaccines in use for COVID, and other important infectious diseases, are safe and effective,” he added.

The study had no commercial funding. Dr. Abara and Dr. Creech have reported no relevant financial relationships. Dr. Klein reported having received grants from Pfizer research support for a COVID vaccine clinical trial, as well as grants from Merck, GlaxoSmithKline, Sanofi Pasteur, and Protein Science (now Sanofi Pasteur).

It’s the end of an era. The Biden administration announced Jan. 30 that it will be ending the twin COVID-19 emergency declarations, marking a major change in the 3-year-old pandemic.

The orders spanned two presidencies. The Trump administration’s Health and Human Services Secretary Alex Azar issued a public health emergency in January 2020. Then-President Donald Trump declared the COVID-19 pandemic a national emergency 2 months later. Both emergency declarations – which remained in effect under President Joe Biden – are set to expire May 11. 

Read on for an overview of how the end of the public health emergency will trigger multiple federal policy changes. 
 

Changes that affect everyone

• There will be cost-sharing changes for COVID-19 vaccines, testing, and certain treatments. One hundred–percent coverage for COVID testing, including free at-home tests, will expire May 11. 
• Telemedicine cannot be used to prescribe controlled substances after May 11, 2023.
• Enhanced federal funding will be phased down through Dec. 31, 2023. This extends the time states must receive federally matched funds for COVID-related services and products, through the Consolidated Appropriations Act of 2023. Otherwise, this would have expired June 30, 2023.
• Emergency use authorizations for COVID-19 treatments and vaccinations will not be affected and/or end on May 11.

Changes that affect people with private health insurance

• Many will likely see higher costs for COVID-19 tests, as free testing expires and cost-sharing begins in the coming months.
• COVID-19 vaccinations and boosters will continue to be covered until the federal government’s vaccination supply is depleted. If that happens, you will need an in-network provider.
• You will still have access to COVID-19 treatments – but that could change when the federal supply dwindles.

Changes that affect Medicare recipients

• Medicare telehealth flexibilities will be extended through Dec. 31, 2024, regardless of public health emergency status. This means people can access telehealth services from anywhere, not just rural areas; can use a smartphone for telehealth; and can access telehealth in their homes. 
• Medicare cost-sharing for testing and treatments will expire May 11, except for oral antivirals. 

Changes that affect Medicaid/CHIP recipients

• Medicaid and Children’s Health Insurance Program (CHIP) recipients will continue to receive approved vaccinations free of charge, but testing and treatment without cost-sharing will expire during the third quarter of 2024.
• The Medicaid continuous enrollment provision will be separated from the public health emergency, and continuous enrollment will end March 31, 2023.

Changes that affect uninsured people

• The uninsured will no longer have access to 100% coverage for these products and services (free COVID-19 treatments, vaccines, and testing). 

Changes that affect health care providers

• There will be changes to how much providers get paid for diagnosing people with COVID-19, ending the enhanced Inpatient Prospective Payment System reimbursement rate, as of May 11, 2023.
• Health Insurance Portability and Accountability Act (HIPAA) potential penalty waivers will end. This allows providers to communicate with patients through telehealth on a smartphone, for example, without violating privacy laws and incurring penalties.

What the experts are saying 

This news organization asked several health experts for their thoughts on ending the emergency health declarations for COVID, and what effects this could have. Many expressed concerns about the timing of the ending, saying that the move could limit access to COVID-related treatments. Others said the move was inevitable but raised concerns about federal guidance related to the decision. 

Question: Do you agree with the timing of the end to the emergency order?

Answer: Robert Atmar, MD, professor of infectious diseases at Baylor College of Medicine in Houston: “A lead time to prepare and anticipate these consequences may ease the transition, compared to an abrupt declaration that ends the declaration.” 

Answer: Georges C. Benjamin, MD, executive director of the American Public Health Association: “I think it’s time to do so. It has to be done in a great, thoughtful, and organized way because we’ve attached so many different things to this public health emergency. It’s going to take time for the system to adapt. [Centers for Disease Control and Prevention] data collection most likely will continue. People are used to reporting now. The CDC needs to give guidance to the states so that we’re clear about what we’re reporting, what we’re not. If we did that abruptly, it would just be a mess.”

Answer: Bruce Farber, MD, chief public health and epidemiology officer at Northwell Health in Manhasset, N.Y.: “I would have hoped to see it delayed.”

Answer: Steven Newmark, JD, chief legal officer and director of policy at the Global Healthy Living Foundation: “While we understand that an emergency cannot last forever, we hope that expanded services such as free vaccination, promotion of widespread vaccination, increased use of pharmacists to administer vaccines, telehealth availability and reimbursement, flexibility in work-from-home opportunities, and more continues. Access to equitable health care should never backtrack or be reduced.”

Q: What will the end of free COVID vaccinations and free testing mean? 

A: Dr. Farber: “There will likely be a decrease in vaccinations and testing. The vaccination rates are very low to begin with, and this will likely lower it further.”

A: Dr. Atmar: “I think it will mean that fewer people will get tested and vaccinated,” which “could lead to increased transmission, although wastewater testing suggests that there is a lot of unrecognized infection already occurring.” 

A: Dr. Benjamin: “That is a big concern. It means that for people, particularly for people who are uninsured and underinsured, we’ve got to make sure they have access to those. There’s a lot of discussion and debate about what the cost of those tests and vaccines will be, and it looks like the companies are going to impose very steep, increasing costs.”

Q: How will this affect higher-risk populations, like people with weakened immune systems? 

A: Dr. Farber: “Without monoclonals [drugs to treat COVID] and free Paxlovid,” people with weakened immune systems “may be undertreated.”

A: Dr. Atmar: “The implications of ongoing widespread virus transmission are that immunocompromised individuals may be more likely to be exposed and infected and to suffer the consequences of such infection, including severe illness. However, to a certain degree, this may already be happening. We are still seeing about 500 deaths/day, primarily in persons at highest risk of severe disease.”

A: Dr. Benjamin:  “People who have good insurance, can afford to get immunized, and have good relations with practitioners probably will continue to be covered. But lower-income individuals and people who really can’t afford to get tested or get immunized would likely become underimmunized and more infected. 

“So even though the federal emergency declaration will go away, I’m hoping that the federal government will continue to encourage all of us to emphasize those populations at the highest risk – those with chronic disease and those who are immunocompromised.”

A: Mr. Newmark: “People who are immunocompromised by their chronic illness or the medicines they take to treat acute or chronic conditions remain at higher risk for COVID-19 and its serious complications. The administration needs to support continued development of effective treatments and updated vaccines to protect the individual and public health. We’re also concerned that increased health care services - such as vaccination or telehealth – may fall back to prepandemic levels while the burden of protection, such as masking, may fall to chronic disease patients alone, which adds to the burden of living with disease.”

Q: What effect will ending Medicaid expansion money have? 

A: Dr. Benjamin: Anywhere from 16 to 20 million people are going to lose in coverage. I’m hoping that states will look at their experience over these last 2 years or so and come to the decision that there were improvements in healthier populations.

Q: Will this have any effect on how the public perceives the pandemic? 

A: Dr. Farber: “It is likely to give the impression that COVID is gone, which clearly is not the case.”

A: Dr. Benjamin: “It’ll be another argument by some that the pandemic is over. People should think about this as kind of like a hurricane. A hurricane comes through and tragically tears up communities, and we have an emergency during that time. But then we have to go through a period of recovery. I’m hoping people will realize that even though the public health emergencies have gone away, that we still need to go through a period of transition ... and that means that they still need to protect themselves, get vaccinated, and wear a mask when appropriate.”

A: Dr. Atmar: “There needs to be messaging that while we are transitioning away from emergency management of COVID-19, it is still a significant public health concern.”

Misinformation regarding COVID-19 has been cited as a public health threat since the beginning of the worldwide pandemic. Doctors and professional organizations are standing guard, hoping to protect patients from any harm that results from mistruths spread by colleagues.

Case in point: Several physicians and the American Board of Pathology filed complaints with Washington and Idaho medical boards alleging that Ryan Cole, MD, a board-certified pathologist who practices in Boise, Idaho, but who also holds a license in Washington, has spread antivaccine and pro-ivermectin statements on social media. Dr. Cole is one of the founders of America’s Frontline Doctors, a right-wing political organization. Dr. Cole did not respond to a request for comment.

Gary W. Procop, MD, CEO, American Board of Pathology, told this news organization that “as physicians and board-certified pathologists, we have a public trust, and we must be accountable to patients, society, and the profession. Misinformation can cause real harm to patients, which may include death. Misinformation diverts patients away from lifesaving vaccination and other preventive measures, promotes viral transmission, and recommends ineffective therapies that may be toxic instead of evidence-based medical care.”
 

Cavalcade of complaints

Several doctors also chimed in with formal complaints alleging that Cole is spreading unreliable information, according to a report from KTVB News. For example, a Boise doctor wrote in his complaint that Dr. Cole is “a major purveyor of misinformation” and called it “amazing” that the physician was continuing to publicly support debunked information about COVID-19 more than a year into the pandemic. The doctor also stated, “Cole is a health menace, abusing his status as a physician to mislead the public.”

As a result of such complaints, the Washington medical board has charged Cole with COVID-19–related violations. It is unclear whether or not the Idaho medical board will sanction the doctor. At least 12 medical boards have sanctioned doctors for similar violations since the start of the pandemic.

The statement of charges from the Washington medical board contends that since March 2021, Dr. Cole has made numerous misleading statements regarding the COVID-19 pandemic, vaccines, the use of ivermectin to treat COVID-19, and the effectiveness of masks.

In addition, the statement alleges that Dr. Cole treated several COVID-19 patients via telemedicine. During these sessions, he prescribed ivermectin, an antiparasite drug that has not been found to have any effectiveness in treating, curing, or preventing COVID-19. One of the patients died after receiving this treatment, according to the complaint.

Citing a study published in the New England Journal of Medicine, Dr. Procop pointed out that use of ivermectin, which is not approved by the U.S. Food and Drug Administration to treat COVID-19, is particularly troubling.

“There is a concern whenever an ineffective treatment is prescribed when more effective and scientifically proven therapies are available. Therapeutics have potential side effects, and toxicities have been associated with the use of ivermectin,” Dr. Procop said. “The benefits of therapy should always outweigh the risks of treatment.”

If the Washington medical board finds that Dr. Cole has engaged in unprofessional conduct, possible sanctions include revocation or suspension of his license. Washington state law also provides for a range of other possible sanctions, including restriction or limitation of his practice, requiring that he complete a specific program of remedial education or treatment, monitoring of his practice, censure or reprimand, probation, a fine of up to $5,000 for each violation, or refunding fees that his practice has billed to and collected from patients. Dr. Cole had until January 30 to respond to the medical board’s statement.

“The American Board of Pathology supports the actions of the Washington State Medical Board regarding their inquiries into any physician that holds license in their state who makes false and misleading medical claims, or provides medical care beyond their scope of practice, as indicated by their training,” Dr. Procop said.
 

Law in limbo

While medical boards are seeking to sanction professionals who spread falsehoods, the pause button has been hit on the California law that allows regulators to punish doctors for spreading false information about COVID-19 vaccinations and treatments.

The law went into effect Jan. 1 but was temporarily halted when U.S. District Judge William B. Shubb of the Eastern District of California granted a preliminary injunction against the law on Jan. 25, according to a report in the Sacramento Bee.

Mr. Shubb said the measure’s definition of “misinformation” was “unconstitutionally vague” under the due process clause of the 14th Amendment. He also criticized the law’s definition of “misinformation” as being “grammatically incoherent.”

“There is a concern whenever an ineffective treatment is prescribed when more effective and scientifically proven therapies are available. Therapeutics have potential side effects, and toxicities have been associated with the use of ivermectin,” Dr. Procop said. “The benefits of therapy should always outweigh the risks of treatment.”

If the Washington medical board finds that Dr. Cole has engaged in unprofessional conduct, possible sanctions include revocation or suspension of his license. Washington state law also provides for a range of other possible sanctions, including restriction or limitation of his practice, requiring that he complete a specific program of remedial education or treatment, monitoring of his practice, censure or reprimand, probation, a fine of up to $5,000 for each violation, or refunding fees that his practice has billed to and collected from patients. Dr. Cole had until January 30 to respond to the medical board’s statement.

“The American Board of Pathology supports the actions of the Washington State Medical Board regarding their inquiries into any physician that holds license in their state who makes false and misleading medical claims, or provides medical care beyond their scope of practice, as indicated by their training,” Dr. Procop said.
 

Law in limbo

While medical boards are seeking to sanction professionals who spread falsehoods, the pause button has been hit on the California law that allows regulators to punish doctors for spreading false information about COVID-19 vaccinations and treatments.

The law went into effect Jan. 1 but was temporarily halted when U.S. District Judge William B. Shubb of the Eastern District of California granted a preliminary injunction against the law on Jan. 25, according to a report in the Sacramento Bee.

Mr. Shubb said the measure’s definition of “misinformation” was “unconstitutionally vague” under the due process clause of the 14th Amendment. He also criticized the law’s definition of “misinformation” as being “grammatically incoherent.”

Misinformation regarding COVID-19 has been cited as a public health threat since the beginning of the worldwide pandemic. Doctors and professional organizations are standing guard, hoping to protect patients from any harm that results from mistruths spread by colleagues.

Case in point: Several physicians and the American Board of Pathology filed complaints with Washington and Idaho medical boards alleging that Ryan Cole, MD, a board-certified pathologist who practices in Boise, Idaho, but who also holds a license in Washington, has spread antivaccine and pro-ivermectin statements on social media. Dr. Cole is one of the founders of America’s Frontline Doctors, a right-wing political organization. Dr. Cole did not respond to a request for comment.

Gary W. Procop, MD, CEO, American Board of Pathology, told this news organization that “as physicians and board-certified pathologists, we have a public trust, and we must be accountable to patients, society, and the profession. Misinformation can cause real harm to patients, which may include death. Misinformation diverts patients away from lifesaving vaccination and other preventive measures, promotes viral transmission, and recommends ineffective therapies that may be toxic instead of evidence-based medical care.”
 

Cavalcade of complaints

Several doctors also chimed in with formal complaints alleging that Cole is spreading unreliable information, according to a report from KTVB News. For example, a Boise doctor wrote in his complaint that Dr. Cole is “a major purveyor of misinformation” and called it “amazing” that the physician was continuing to publicly support debunked information about COVID-19 more than a year into the pandemic. The doctor also stated, “Cole is a health menace, abusing his status as a physician to mislead the public.”

As a result of such complaints, the Washington medical board has charged Cole with COVID-19–related violations. It is unclear whether or not the Idaho medical board will sanction the doctor. At least 12 medical boards have sanctioned doctors for similar violations since the start of the pandemic.

The statement of charges from the Washington medical board contends that since March 2021, Dr. Cole has made numerous misleading statements regarding the COVID-19 pandemic, vaccines, the use of ivermectin to treat COVID-19, and the effectiveness of masks.

In addition, the statement alleges that Dr. Cole treated several COVID-19 patients via telemedicine. During these sessions, he prescribed ivermectin, an antiparasite drug that has not been found to have any effectiveness in treating, curing, or preventing COVID-19. One of the patients died after receiving this treatment, according to the complaint.

Citing a study published in the New England Journal of Medicine, Dr. Procop pointed out that use of ivermectin, which is not approved by the U.S. Food and Drug Administration to treat COVID-19, is particularly troubling.

“There is a concern whenever an ineffective treatment is prescribed when more effective and scientifically proven therapies are available. Therapeutics have potential side effects, and toxicities have been associated with the use of ivermectin,” Dr. Procop said. “The benefits of therapy should always outweigh the risks of treatment.”

U.S. health officials want to simplify the recommended COVID-19 vaccine protocol, making it more like the process for annual flu shots.

The U.S. Food and Drug Administration is suggesting a single annual shot. The formulation would be selected in June targeting the most threatening COVID-19 strains, and then people could get a shot in the fall when people begin spending more time indoors and exposure increases. 

Some people, such as those who are older or immunocompromised, may need more than one dose.

A national advisory committee is expected to vote on the proposal at a meeting Jan. 26.

People in the United States have been much less likely to get an updated COVID-19 booster shot, compared with widespread uptake of the primary vaccine series. In its proposal, the FDA indicated it hoped a single annual shot would overcome challenges created by the complexity of the process – both in messaging and administration – attributed to that low booster rate. Nine in 10 people age 12 or older got the primary vaccine series in the United States, but only 15% got the latest booster shot for COVID-19.

About half of children and adults in the U.S. get an annual flu shot, according to Centers for Disease Control and Prevention data.

The FDA also wants to move to a single COVID-19 vaccine formulation that would be used for primary vaccine series and for booster shots.

COVID-19 cases, hospitalizations, and deaths are trending downward, according to the data tracker from the New York Times. Cases are down 28%, with 47,290 tallied daily. Hospitalizations are down 22%, with 37,474 daily. Deaths are down 4%, with an average of 489 per day as of Jan. 22.

The only HIV vaccine nearing the completion of testing trials is not effective at preventing HIV, officials announced Wednesday.

The vaccine had been in development since 2019 and was given to 3,900 study participants through October 2022, but data shows it does not protect against HIV compared with a placebo, according to developer Janssen Pharmaceutical.

Experts estimate the failure means there won’t be another potential vaccine on the horizon for 3 to 5 years, the New York Times reported.

“It’s obviously disappointing,” Anthony Fauci, MD, former head of the National Institute of Allergy and Infectious Diseases, told MSNBC, noting that other areas of HIV treatment research are promising. “I don’t think that people should give up on the field of the HIV vaccine.”

No safety issues had been identified with the vaccine during the trial, which studied the experimental treatment in men who have sex with men or with transgender people.

There is no cure for HIV, but disease progression can be managed with existing treatments. HIV attacks the body’s immune system and destroys white blood cells, increasing the risk of other infections. More than 1.5 million people worldwide were infected with HIV in 2021 and 38.4 million people are living with the virus, according to UNAIDS.

On Twitter, as in real life, it’s a question on many minds: When should we think about the next COVID-19 vaccine? Or should we?

For some people who have received a two-dose primary series and all the recommended boosters, that could mean a sixth shot since COVID-19 vaccines became available. But is even that enough (or too much)?

At this point, no one knows for sure, but new guidance may be on the docket.

On Jan. 26, the FDA’s Vaccines and Related Biological Products Advisory Committee is meeting. On the agenda is discussion about plans for future vaccinations for COVID-19.The committee, made up of external advisers, evaluates data on vaccines and other products for the agency.

According to the FDA announcement, after the meeting, “the FDA will consider whether to recommend adjustments to the current authorizations and approvals, and the FDA will consider the most efficient and transparent process to use for selection of strains for inclusion in the primary and booster vaccines.”

From there, the CDC will take up the issue and decide on recommendations.

The issue is important, as more than 550 Americans a day are still dying from COVID-19, as of the week ending Jan. 13, the CDC reported. That’s up from 346 a day for the week ending Dec. 28.

Yet, uptake of the newest vaccine, the bivalent booster, has been slow. As of Jan. 11, just 15.9% of the population 5 years and up has gotten it; for those most vulnerable to COVID19 – those 65 and up – the number is just 39%.
 

COVID vaccines, 2023 and beyond

Meanwhile, infectious disease experts have widely differing views on what the vaccination landscape of 2023 and beyond should look like. Among the areas of disagreement are how effective the bivalent vaccine is, which people most need another shot, and what type of vaccine is best.

“I think we probably will need another booster,” says Peter Hotez, MD, PhD, dean of the National School of Tropical Medicine at Baylor College of Medicine, and codirector of the Center for Vaccine Development at Texas Children’s Hospital in Houston. “The question is, what is it going to be? Is it going to be the same bivalent that we just got, or will it be a new bivalent or even a trivalent?” 

The trivalent booster, he suggested, might include something more protective against XBB.1.5.

The bivalent booster gives “broadened immunity” that is improved from the original booster shots, says Eric Topol, MD, founder and director of the Scripps Research Translational Institute in La Jolla, Calif., and editor-in-chief of Medscape, WebMD’s sister site for health professionals.

In his publication Ground Truths, Dr. Topol on Jan. 11 explained how new data caused him to reverse his previously skeptical view of how the FDA authorized the bivalent vaccine in September without data on how it affected humans at the time.

Paul Offit, MD, director of the Vaccine Education Center and a professor of pediatrics at the Children’s Hospital of Philadelphia, is a member of the FDA advisory committee for vaccines. He still takes a dimmer view of more bivalent booster vaccines, at least as a blanket recommendation. 

While he acknowledges that boosters can help some groups – such as older adults, people with multiple health conditions, and those with compromised immune systems – he opposes a recommendation that’s population-wide.

“People who fall into those three groups do benefit,” he says, “but the recommendation is everyone over 6 months get the bivalent, and what I’m asking is, ‘Where is the data that a healthy 12-year-old boy needs a booster to stay out of the hospital?’ ”
 

Evolving research

“We are trying to understand how to stay one step ahead rather than several steps behind [the virus],“ says Michael Osterholm, PhD, director of the Center for Infectious Disease Research and Policy at the University of Minnesota.

Among the key questions: How well can a vaccine work against a single subvariant, when no one can say for sure what the next predominant subvariant will be?

Much more research has become available recently about the bivalent vaccine and its effectiveness, Dr. Osterholm says. “The bivalent vaccine is working as well as we could have expected,” he says, especially in high-risk people and in those over age 65. “The challenge we have is, what does that mean going forward?”

In his review, Dr. Topol concludes: “There is now more than ample, highly consistent evidence via lab studies and clinical outcomes to support the bivalent’s benefit over the original booster.”

Among other evidence, he looked at eight studies, including four that used a live virus as part of the research. Six of the eight studies showed the bivalent booster is more effective against the BA.5 variant, compared with the original booster shots. Two others showed no real difference.

“The four live virus studies offer consistent evidence of broadened immunity for the BA.5 vaccine that is improved over the original booster shots,” Dr. Topol wrote. The evidence also found the bivalent antibody response superior against XBB, he wrote.

Dr. Topol also cited CDC data that supports the benefits of the bivalent shot on hospitalization in older adults. During November, hospitalization of adults 65 and above was 2.5 times higher for those vaccinated who did not get the booster, compared to those who got the updated bivalent booster.

Boosters do matter, Dr. Offit says. “But not for all.” In a perspective published Jan. 11 in the New England Journal of Medicine – the same issue that published the two studies finding few differences between the original and bivalent – Dr. Offit wrote that boosting is best reserved for vulnerable groups.

Chasing the variants with a bivalent vaccine, he says, “has not panned out. There remains no evidence that a bivalent vaccine is any better than what we had. Please, show me the data that one is better than the other.”

Dr. Offit believes the goal should not be to prevent all symptomatic infections in healthy, young people by boosting them “with vaccines containing mRNA from strains that might disappear a few months later.”

The CDC needs to parse the data by subgroups, Dr. Offit says. “The critical question is, ‘Who gets hospitalized and who is dying? Who are they?’ ”

That data should take into account age, ethnicity, vaccine history, and other factors, Dr. Offit says, because right now, there is no great data to say, “OK, everyone gets a boost.”
 

Future vaccine costs

Another debate – for not only current boosters but future ones, too – centers on cost. Without congressional action to fund more vaccines, vaccine makers have suggested their prices may reach $130 a dose, compared with the average $20-per-dose cost the federal government pays now, according to a Kaiser Family Foundation report.

The government has spent more than $30 billion on COVID-19 vaccines, including the bivalent, to provide them free of charge.

The suggested price increase infuriated many. On Jan. 10, Sen. Bernie Sanders (I-Vt.), incoming chair of the Senate Committee on Health, Education, Labor and Pensions, sent a letter to Moderna CEO Stéphane Bancel, urging him to reconsider and refrain from any price increase.

“The huge increase in price that you have proposed will have a significantly negative impact on the budgets of Medicaid, Medicare and other government programs that will continue covering the vaccine without cost-sharing for patients.”

He pointed out, too, the $19 billion in profits Moderna has made over the past 2 years.

While most people with health insurance would likely still get the vaccines and booster for free, according to the Kaiser analysis, will a higher price discourage people from keeping up with recommended vaccinations, including a possible new booster?

“I think so, yes,” Dr. Hotez says, noting that vaccine reluctance is high as it is, even with free vaccinations and easy access.

“The government is balking at paying for the boosters,” he says. “I think it’s very tone deaf from the pharmaceutical companies [to increase the price]. Given all the help they’ve gotten from the American people, I think they should not be gouging at this point.”

He noted that the federal government provided not just money to the companies for the vaccines, but a “glide path” through the FDA for the vaccine approvals.
 

Are new, variant-specific boosters coming?

Are Moderna, Pfizer-BioNTech, and others developing more variant-specific vaccines, boosters, or other advances?

Novavax, approved in July 2022 as a primary series and in some cases as a booster, is “also developing an Omicron-containing bivalent vaccine at the direction of public health agencies,” says spokesperson Alison Chartan.

Pfizer responded: “When and if we have something to share we will let you know.”

Moderna did not respond.

Is it going to be the same bivalent that we just got, or will it be a new bivalent or even a trivalent?” 

The trivalent booster, he suggested, might include something more protective against XBB.1.5.

The bivalent booster gives “broadened immunity” that is improved from the original booster shots, says Eric Topol, MD, founder and director of the Scripps Research Translational Institute in La Jolla, Calif., and editor-in-chief of Medscape, WebMD’s sister site for health professionals.

In his publication Ground Truths, Dr. Topol on Jan. 11 explained how new data caused him to reverse his previously skeptical view of how the FDA authorized the bivalent vaccine in September without data on how it affected humans at the time.

Paul Offit, MD, director of the Vaccine Education Center and a professor of pediatrics at the Children’s Hospital of Philadelphia, is a member of the FDA advisory committee for vaccines. He still takes a dimmer view of more bivalent booster vaccines, at least as a blanket recommendation. 

While he acknowledges that boosters can help some groups – such as older adults, people with multiple health conditions, and those with compromised immune systems – he opposes a recommendation that’s population-wide.

“People who fall into those three groups do benefit,” he says, “but the recommendation is everyone over 6 months get the bivalent, and what I’m asking is, ‘Where is the data that a healthy 12-year-old boy needs a booster to stay out of the hospital?’ ”
 

Evolving research

“We are trying to understand how to stay one step ahead rather than several steps behind [the virus],“ says Michael Osterholm, PhD, director of the Center for Infectious Disease Research and Policy at the University of Minnesota.

Among the key questions: How well can a vaccine work against a single subvariant, when no one can say for sure what the next predominant subvariant will be?

Much more research has become available recently about the bivalent vaccine and its effectiveness, Dr. Osterholm says. “The bivalent vaccine is working as well as we could have expected,” he says, especially in high-risk people and in those over age 65. “The challenge we have is, what does that mean going forward?”

In his review, Dr. Topol concludes: “There is now more than ample, highly consistent evidence via lab studies and clinical outcomes to support the bivalent’s benefit over the original booster.”

Among other evidence, he looked at eight studies, including four that used a live virus as part of the research. Six of the eight studies showed the bivalent booster is more effective against the BA.5 variant, compared with the original booster shots. Two others showed no real difference.

“The four live virus studies offer consistent evidence of broadened immunity for the BA.5 vaccine that is improved over the original booster shots,” Dr. Topol wrote. The evidence also found the bivalent antibody response superior against XBB, he wrote.

Dr. Topol also cited CDC data that supports the benefits of the bivalent shot on hospitalization in older adults. During November, hospitalization of adults 65 and above was 2.5 times higher for those vaccinated who did not get the booster, compared to those who got the updated bivalent booster.

Boosters do matter, Dr. Offit says. “But not for all.” In a perspective published Jan. 11 in the New England Journal of Medicine – the same issue that published the two studies finding few differences between the original and bivalent – Dr. Offit wrote that boosting is best reserved for vulnerable groups.

Chasing the variants with a bivalent vaccine, he says, “has not panned out. There remains no evidence that a bivalent vaccine is any better than what we had. Please, show me the data that one is better than the other.”

Dr. Offit believes the goal should not be to prevent all symptomatic infections in healthy, young people by boosting them “with vaccines containing mRNA from strains that might disappear a few months later.”

The CDC needs to parse the data by subgroups, Dr. Offit says. “The critical question is, ‘Who gets hospitalized and who is dying? Who are they?’ ”

That data should take into account age, ethnicity, vaccine history, and other factors, Dr. Offit says, because right now, there is no great data to say, “OK, everyone gets a boost.”
 

Future vaccine costs

Another debate – for not only current boosters but future ones, too – centers on cost. Without congressional action to fund more vaccines, vaccine makers have suggested their prices may reach $130 a dose, compared with the average $20-per-dose cost the federal government pays now, according to a Kaiser Family Foundation report.

The government has spent more than $30 billion on COVID-19 vaccines, including the bivalent, to provide them free of charge.

The suggested price increase infuriated many. On Jan. 10, Sen. Bernie Sanders (I-Vt.), incoming chair of the Senate Committee on Health, Education, Labor and Pensions, sent a letter to Moderna CEO Stéphane Bancel, urging him to reconsider and refrain from any price increase.

“The huge increase in price that you have proposed will have a significantly negative impact on the budgets of Medicaid, Medicare and other government programs that will continue covering the vaccine without cost-sharing for patients.”

He pointed out, too, the $19 billion in profits Moderna has made over the past 2 years.

While most people with health insurance would likely still get the vaccines and booster for free, according to the Kaiser analysis, will a higher price discourage people from keeping up with recommended vaccinations, including a possible new booster?

“I think so, yes,” Dr. Hotez says, noting that vaccine reluctance is high as it is, even with free vaccinations and easy access.

“The government is balking at paying for the boosters,” he says. “I think it’s very tone deaf from the pharmaceutical companies [to increase the price]. Given all the help they’ve gotten from the American people, I think they should not be gouging at this point.”

He noted that the federal government provided not just money to the companies for the vaccines, but a “glide path” through the FDA for the vaccine approvals.
 

Are new, variant-specific boosters coming?

Are Moderna, Pfizer-BioNTech, and others developing more variant-specific vaccines, boosters, or other advances?

Novavax, approved in July 2022 as a primary series and in some cases as a booster, is “also developing an Omicron-containing bivalent vaccine at the direction of public health agencies,” says spokesperson Alison Chartan.

Pfizer responded: “When and if we have something to share we will let you know.”

Moderna did not respond.

A vaccine database found a possible link between the Pfizer/BioNTech bivalent COVID-19 vaccine and ischemic strokes in people over 65 who got the shot, the Centers for Disease Control and Prevention and the Food and Drug Administration said in a joint news release.

The release did not recommend people change their vaccine practices, saying the database finding probably did not represent a “true clinical risk.” The CDC said everybody, including people over 65, should stay up to date on their COVID vaccines, including the bivalent booster.

The news release said the Vaccine Safety Datalink (VSD), “a near real-time surveillance system,” raised a safety concern about the Pfizer/BioNTech booster.

“Rapid-response investigation of the signal in the VSD raised a question of whether people 65 and older who have received the Pfizer-BioNTech COVID-19 Vaccine, Bivalent were more likely to have an ischemic stroke in the 21 days following vaccination compared with days 22-44 following vaccination,” the news release said.

Ischemic strokes are blockages of blood to the brain, often caused by blood clots.

“Although the totality of the data currently suggests that it is very unlikely that the signal in VSD (Vaccine Safety Datalink) represents a true clinical risk, we believe it is important to share this information with the public, as we have in the past, when one of our safety monitoring systems detects a signal,” the release said.

No higher likelihood of strokes linked to the Pfizer bivalent vaccine had been found by Pfizer/BioNTech, the Department of Veterans Affairs, the Vaccine Adverse Event Reporting System maintained by the CDC and the FDA, or other agencies that monitor reactions of vaccines, the news release said. No safety issues about strokes have been identified with the Moderna bivalent vaccine. 

CNN, citing a CDC official, reported that about 550,000 seniors who got Pfizer bivalent boosters were tracked by the VSD, and 130 of them had strokes within 3 weeks of getting the shot. None of those 130 people died, CNN said. The official spoke on the condition of anonymity because they weren’t authorized to share the data. 

The issue will be discussed at the January meeting of the FDA’s Vaccines and Related Biological Products Advisory Committee.

In a joint statement, Pfizer and BioNTech said: “Neither Pfizer and BioNTech nor the CDC or FDA have observed similar findings across numerous other monitoring systems in the U.S. and globally and there is no evidence to conclude that ischemic stroke is associated with the use of the companies’ COVID-19 vaccines.”

Bivalent boosters contain two strains of vaccine – one to protect against the original COVID-19 virus and another targeting Omicron subvariants.

The percentage of kindergarteners in the United States who have received routine vaccines to protect against illnesses such as measles, whooping cough, and polio has declined for 2 straight years, a new study has found.

Drops in vaccine coverage leave communities more susceptible to outbreaks of vaccine-preventable diseases, such as those that occurred in 2022, public health officials said.

Coverage for four vaccines – against measles, mumps, and rubella (MMR); diphtheria, tetanus, and acellular pertussis (DTaP); poliovirus; and varicella – among kindergarten students was about 95% in 2019-2020.

The rate fell to 94% the following year.

For the 2021-2022 school year, coverage dropped another point, to 93%, according to the report, published online in Morbidity and Mortality Weekly Report.

The rate of vaccination overall remains high, but about 250,000 kindergarten students may not be protected against measles, the researchers estimate. Measles, which is highly infectious, can lead to serious illness and even death in children who have not been vaccinated against the virus.

“In 2022, two communities in the United States responded to outbreaks of measles where children have been hospitalized,” Georgina Peacock, MD, MPH, director of the immunization services division of the Centers for Disease Control and Prevention, said in a media briefing about the report. “One community reported a case of paralytic polio in an unvaccinated person. These outbreaks were preventable. The best way to prevent these diseases and their devastating impact on children is through vaccination.”
 

Exemptions steady

For the new study, Ranee Seither, MPH, with the CDC’s National Center for Immunization and Respiratory Diseases and her colleagues analyzed data reported by states to estimate nationwide coverage for the four routine vaccines.

The number of students with exemptions remained low, at 2.6%, but another 3.9% who were without exemptions were not up to date with the MMR vaccine, the investigators report.

In a separate study, researchers found that vaccination coverage for 2-year-olds has increased. Approximately 70% of children were up to date with a seven-vaccine series by age 24 months. The coverage rate was higher for children born during 2018-2019 than for those born during 2016-2017.

Although the COVID-19 pandemic was not associated with decreased vaccination rates in this younger age group overall, coverage fell by 4-5 percentage points for children living below the poverty level or in rural areas, according to the study.

In addition, uninsured children were eight times more likely than those with private insurance to not be vaccinated by their second birthday, the researchers found.

Strategies to increase vaccination coverage include enforcing school vaccination requirements and holding vaccination clinics at schools, the CDC said.

“Providers should review children’s histories and recommend needed vaccinations during every clinical encounter and address parental hesitancy to help reduce disparities and ensure that all children are protected from vaccine-preventable diseases,” the agency said.

To that end, the agency launched an initiative this week called Let’s RISE (Routine Immunizations on Schedule for Everyone) to provide clinicians with resources to help patients get on track with their immunizations.
 

Hundreds of thousands unprotected

MMR vaccination coverage for kindergartners is the lowest it has been in over a decade, Dr. Peacock noted. Decreased coverage for kindergarten students might be tied to pandemic-related disruptions in health care systems and schools, she said. School administrators and parents may have been less focused on routine vaccination paperwork amid the return to in-person learning, for instance.

Hesitancy about COVID vaccines could be affecting routine vaccinations. “That’s something that we are watching very closely,” Dr. Peacock said.

The 2-point decrease in vaccination coverage “translates to hundreds of thousands of children starting school without being fully protected” against preventable diseases that can spread easily in classrooms, Sean O’Leary, MD, chair of the American Academy of Pediatrics’ Committee on Infectious Diseases, said.

Despite the drop in coverage, Dr. O’Leary said he saw some encouraging signs in the data: Nonmedical exemptions for kindergarten students have not increased. And the vast majority of parents are still having their children vaccinated. At the same time, the reports highlight a need to address child poverty and improve vaccine access in rural areas, he said.

Vaccinations have substantially reduced morbidity and mortality from many infectious diseases. Despite the clear value of vaccinations in public health, efforts to better understand adverse events (AEs) following immunization are important to sustain public trust and vaccine confidence. Noninfectious inflammation of the heart may manifest as myocarditis or pericarditis, or occasionally, with shared signs and symptoms of each, as myopericarditis. This is a rare AE following some immunizations. Vaccine-associated myocarditis, pericarditis, or myopericarditis (VAMP) has been most clearly associated with smallpox vaccines and mRNA COVID-19 vaccines.^1-6 Although extremely rare, VAMP also has been associated with other vaccines.^7,8 Limited information exists to guide shared clinical decision making on COVID-19 vaccination in persons with a history of VAMP. It is unknown whether individuals with a history of VAMP are at higher risk for developing a recurrence or experiencing a more severe outcome following COVID-19 vaccination.

Methods

As part of the collaborative public health mission with the Centers for Disease Control and Prevention (CDC) for enhanced vaccine AE surveillance, the Defense Health Agency Immunization Healthcare Division (IHD) maintains a clinical database of service members and beneficiaries referred for suspected AEs following immunizations. A review of all AEs following immunization cases in this database from January 1, 2003, through February 28, 2022, identified individuals meeting the following criteria: (a) VAMP prior to receipt of COVID-19 vaccine; (b) receipt of COVID-19 vaccine in 2021; and (c) medical documentation in available electronic health records sufficient to describe health status at least 30 days following COVID-19 vaccination.⁹ If medical entries suggested cardiac symptoms following a COVID-19 vaccine, additional information was sought to verify VAMP based on current published criteria.^10,11 Both the initial VAMP cases and the suspected COVID-19 VAMP cases were adjudicated by a team of vaccine experts and specialists in immunology, cardiology, and preventive medicine.

This retrospective review was approved and conducted in accordance with the Walter Reed National Military Medical Center Institutional Review Board protocol #20664. All individuals with recurrent VAMP consented to share their health records and clinical details.

Results

Among 9260 cases in the IHD database, 431 met the case definition for VAMP.

Among the 179 patients included in this analysis, 171 (96%) were male. Their median age was 39 years at the time of COVID-19 vaccination.

Within 1 month of receipt of any COVID-19 vaccine, 11 individuals had documented symptoms suggesting cardiac involvement, specifically, chest pain, palpitations, or dyspnea. After cardiac evaluation, 4 patients met the criteria for VAMP after COVID-19 vaccination.^10,11 Seven patients either did not meet the criteria for VAMP or had alternative causes for their symptoms.

Two men aged 49 and 50 years with a history of vaccine-associated myocarditis following smallpox vaccination (Dryvax and ACAM2000) developed myocarditis 3 days after their second dose of the Moderna vaccine. One of these patients received a Pfizer-BioNTech booster 10 months later with no recurrence of symptoms. A 55-year-old man with a history of vaccine-associated myocarditis following Dryvax vaccination developed myocarditis 2 days after his Pfizer-BioNTech booster. None of the patients who developed post-COVID-19 VAMP reported residual symptoms from their initial VAMP episode, which occurred 12 to 18 years earlier. All were hospitalized briefly for observation and had complete symptom resolution within 6 weeks.

A 25-year-old man developed pericarditis 4 days after his second Pfizer-BioNTech vaccination. His previous ACAM2000 vaccine-associated myocarditis occurred 3 years earlier, with no residual symptoms. Of note, he had a mild COVID-19 infection 78 days before the onset of his pericarditis. After the onset of his COVID-19 vaccine-associated pericarditis, he continued to experience transient bouts of chest pressure and exertional dyspnea that resolved within 7 months of onset.

The median interval between COVID-19 vaccine doses in those who developed post-COVID-19 VAMP was within the recommended mRNA vaccine dosing intervals of 3 to 4 weeks and was consistent with the median mRNA vaccine dosing intervals among the entire cohort.

Due to the small cohort size and other limitations of this study, the suggested rate of cardiac injury in this review (4 cases in 179 persons, or 2.2%) is an imprecise estimate of risk in a small population (95% CI, 0.1%-4.4%). While this rate may seem higher than expected within the general population after COVID-19 vaccination, it is lower than the estimated lifetime risk of recurrent myocarditis from any cause.^6,12

Discussion

To our knowledge, this is the first report describing cardiac outcomes after COVID-19 vaccination among a cohort of individuals with prior history of VAMP. Four cases of COVID-19 VAMP were identified among 179 patients with previous VAMP. All cases had experienced VAMP after the smallpox vaccine several years earlier, with complete resolution of symptoms. Three cases presented with recurrent VAMP after their second dose of an mRNA COVID-19 vaccine, and one after an mRNA booster dose. All fully recovered over the course of several months.

Myocarditis is a heterogeneous inflammatory injury with diverse, sometimes idiopathic, etiologies.¹³ In contrast to infection-related cardiac injury, prior reports of vaccine-associated myocarditis have suggested a hypersensitivity reaction characterized by patchy eosinophilic infiltrates, a benign clinical course, and good prognosis.^2,3

There are several common features between VAMP after smallpox and COVID-19 vaccination. Cases occur predominantly in young men. The onset of symptoms after smallpox vaccine (mean, 10 days) and after mRNA COVID-19 vaccine (mean, 3 days) appears to correspond to the timing of peak postvaccination pro-inflammatory cytokine elevation.¹⁴ While all VAMP cases are serious events, the majority of patients appear to have a relatively benign clinical course with rapid and full recovery.¹³

Patients who have experienced an inflammatory cardiac injury may be at higher risk for recurrence, but quantifying risk of this rare phenomenon is challenging. Cases of VAMP after the COVID-19 vaccine have occasionally been reported in patients with previous cardiac injury unrelated to vaccination.^15-17 The cases presented here represent the first report of recurrent VAMP following prior non-COVID-19 vaccinations.

Most patients with prior VAMP in this cohort did not experience cardiac-suggestive symptoms following COVID-19 vaccination. Among 11 patients who developed symptoms, 3 had confirmed myocarditis and 1 had confirmed pericarditis. The clinical course for these patients with recurrent VAMP was observed to be no different in severity or duration from those who experience new-onset VAMP.⁴ All other patients not meeting criteria for VAMP or having alternative explanations for their symptoms also had a benign clinical course. Nonetheless, of the study cohort of 179, recurrent VAMP was diagnosed in 4 of the 11 who developed cardiac-suggestive symptoms following COVID-19 vaccination. The importance of cardiac evaluation should be emphasized for any patient presenting with chest pain, dyspnea, or other cardiac-suggestive symptoms following vaccination.

Strengths and Limitations

The strength of this review of VAMP recurrence associated with COVID-19 vaccination derives from our large and unique longitudinal database of VAMP among current and prior service members. Additionally, the IHD’s ongoing enhanced vaccine AEs surveillance provides the opportunity to contact patients and review their electronic health records over an extended interval of time.

When interpreting this report’s implications, limitations inherent to any retrospective case review should be considered. The cohort of cases of prior VAMP included primarily healthy, fit, young service members; this population is not representative of the general population. The cohort included prior VAMP cases that generally occurred after smallpox vaccination. Experiences after smallpox vaccine may not apply to cardiac injury from other vaccines or etiologies. By the nature of this review, the population studied at the time of COVID-19 vaccination was somewhat older than those most likely to develop an initial bout of VAMP.² This review was limited by information available in the electronic health records of a small number of patients. Subclinical cases of VAMP and cases without adequate clinical evaluation also could not be included.

Conclusions

Noninfectious inflammation of the heart (myocarditis, pericarditis, or myopericarditis) is a rare AE following certain vaccines, especially live replicating smallpox vaccine and mRNA COVID-19 vaccines. In this observational analysis, the majority of patients with previous VAMP successfully received a COVID-19 vaccine without recurrence. The 4 patients who were identified with recurrent VAMP following COVID-19 vaccination all recovered with supportive care. While the CDC endorses that individuals with a history of infectious myocarditis may receive COVID-19 vaccine after symptoms have resolved, there is currently insufficient safety data regarding COVID-19 vaccination of those with prior non-COVID-19 VAMP or following subsequent COVID-19 vaccination in those with prior VAMP related to COVID-19.¹⁰ For these individuals, COVID-19 vaccination is a precaution.¹⁰ Although insufficient to determine a precise level of risk, this report does provide data on which to base the CDC-recommended shared decision-making counseling of these patients. More research is needed to better define factors that increase risk for, or protection from, immune-mediated AEs following immunization, including VAMP. While benefits of vaccination have clearly outweighed risks during the COVID-19 pandemic, such research may optimize future vaccine recommendations.¹⁸

Vaccinations have substantially reduced morbidity and mortality from many infectious diseases. Despite the clear value of vaccinations in public health, efforts to better understand adverse events (AEs) following immunization are important to sustain public trust and vaccine confidence. Noninfectious inflammation of the heart may manifest as myocarditis or pericarditis, or occasionally, with shared signs and symptoms of each, as myopericarditis. This is a rare AE following some immunizations. Vaccine-associated myocarditis, pericarditis, or myopericarditis (VAMP) has been most clearly associated with smallpox vaccines and mRNA COVID-19 vaccines.^1-6 Although extremely rare, VAMP also has been associated with other vaccines.^7,8 Limited information exists to guide shared clinical decision making on COVID-19 vaccination in persons with a history of VAMP. It is unknown whether individuals with a history of VAMP are at higher risk for developing a recurrence or experiencing a more severe outcome following COVID-19 vaccination.

Methods

As part of the collaborative public health mission with the Centers for Disease Control and Prevention (CDC) for enhanced vaccine AE surveillance, the Defense Health Agency Immunization Healthcare Division (IHD) maintains a clinical database of service members and beneficiaries referred for suspected AEs following immunizations. A review of all AEs following immunization cases in this database from January 1, 2003, through February 28, 2022, identified individuals meeting the following criteria: (a) VAMP prior to receipt of COVID-19 vaccine; (b) receipt of COVID-19 vaccine in 2021; and (c) medical documentation in available electronic health records sufficient to describe health status at least 30 days following COVID-19 vaccination.⁹ If medical entries suggested cardiac symptoms following a COVID-19 vaccine, additional information was sought to verify VAMP based on current published criteria.^10,11 Both the initial VAMP cases and the suspected COVID-19 VAMP cases were adjudicated by a team of vaccine experts and specialists in immunology, cardiology, and preventive medicine.

This retrospective review was approved and conducted in accordance with the Walter Reed National Military Medical Center Institutional Review Board protocol #20664. All individuals with recurrent VAMP consented to share their health records and clinical details.

Results

Among 9260 cases in the IHD database, 431 met the case definition for VAMP.

Among the 179 patients included in this analysis, 171 (96%) were male. Their median age was 39 years at the time of COVID-19 vaccination.

Within 1 month of receipt of any COVID-19 vaccine, 11 individuals had documented symptoms suggesting cardiac involvement, specifically, chest pain, palpitations, or dyspnea. After cardiac evaluation, 4 patients met the criteria for VAMP after COVID-19 vaccination.^10,11 Seven patients either did not meet the criteria for VAMP or had alternative causes for their symptoms.

Two men aged 49 and 50 years with a history of vaccine-associated myocarditis following smallpox vaccination (Dryvax and ACAM2000) developed myocarditis 3 days after their second dose of the Moderna vaccine. One of these patients received a Pfizer-BioNTech booster 10 months later with no recurrence of symptoms. A 55-year-old man with a history of vaccine-associated myocarditis following Dryvax vaccination developed myocarditis 2 days after his Pfizer-BioNTech booster. None of the patients who developed post-COVID-19 VAMP reported residual symptoms from their initial VAMP episode, which occurred 12 to 18 years earlier. All were hospitalized briefly for observation and had complete symptom resolution within 6 weeks.

A 25-year-old man developed pericarditis 4 days after his second Pfizer-BioNTech vaccination. His previous ACAM2000 vaccine-associated myocarditis occurred 3 years earlier, with no residual symptoms. Of note, he had a mild COVID-19 infection 78 days before the onset of his pericarditis. After the onset of his COVID-19 vaccine-associated pericarditis, he continued to experience transient bouts of chest pressure and exertional dyspnea that resolved within 7 months of onset.

The median interval between COVID-19 vaccine doses in those who developed post-COVID-19 VAMP was within the recommended mRNA vaccine dosing intervals of 3 to 4 weeks and was consistent with the median mRNA vaccine dosing intervals among the entire cohort.

Due to the small cohort size and other limitations of this study, the suggested rate of cardiac injury in this review (4 cases in 179 persons, or 2.2%) is an imprecise estimate of risk in a small population (95% CI, 0.1%-4.4%). While this rate may seem higher than expected within the general population after COVID-19 vaccination, it is lower than the estimated lifetime risk of recurrent myocarditis from any cause.^6,12

Discussion

To our knowledge, this is the first report describing cardiac outcomes after COVID-19 vaccination among a cohort of individuals with prior history of VAMP. Four cases of COVID-19 VAMP were identified among 179 patients with previous VAMP. All cases had experienced VAMP after the smallpox vaccine several years earlier, with complete resolution of symptoms. Three cases presented with recurrent VAMP after their second dose of an mRNA COVID-19 vaccine, and one after an mRNA booster dose. All fully recovered over the course of several months.

Myocarditis is a heterogeneous inflammatory injury with diverse, sometimes idiopathic, etiologies.¹³ In contrast to infection-related cardiac injury, prior reports of vaccine-associated myocarditis have suggested a hypersensitivity reaction characterized by patchy eosinophilic infiltrates, a benign clinical course, and good prognosis.^2,3

There are several common features between VAMP after smallpox and COVID-19 vaccination. Cases occur predominantly in young men. The onset of symptoms after smallpox vaccine (mean, 10 days) and after mRNA COVID-19 vaccine (mean, 3 days) appears to correspond to the timing of peak postvaccination pro-inflammatory cytokine elevation.¹⁴ While all VAMP cases are serious events, the majority of patients appear to have a relatively benign clinical course with rapid and full recovery.¹³

Patients who have experienced an inflammatory cardiac injury may be at higher risk for recurrence, but quantifying risk of this rare phenomenon is challenging. Cases of VAMP after the COVID-19 vaccine have occasionally been reported in patients with previous cardiac injury unrelated to vaccination.^15-17 The cases presented here represent the first report of recurrent VAMP following prior non-COVID-19 vaccinations.

Most patients with prior VAMP in this cohort did not experience cardiac-suggestive symptoms following COVID-19 vaccination. Among 11 patients who developed symptoms, 3 had confirmed myocarditis and 1 had confirmed pericarditis. The clinical course for these patients with recurrent VAMP was observed to be no different in severity or duration from those who experience new-onset VAMP.⁴ All other patients not meeting criteria for VAMP or having alternative explanations for their symptoms also had a benign clinical course. Nonetheless, of the study cohort of 179, recurrent VAMP was diagnosed in 4 of the 11 who developed cardiac-suggestive symptoms following COVID-19 vaccination. The importance of cardiac evaluation should be emphasized for any patient presenting with chest pain, dyspnea, or other cardiac-suggestive symptoms following vaccination.
