Vaccines

An increasing number of people who are unvaccinated and pregnant are being hospitalized for COVID-19, report investigators who saw hospital admissions double in a single year.

“With the surge, we had expected to begin treating patients who developed severe or critical illness again in pregnancy,” says Emily Adhikari, MD, from the University of Texas Southwestern Medical Center in Dallas. “But we did not expect the level of respiratory illness that we began to see in our patients. That was a surprise and an alarming finding that we felt was really important to get out there.”

The researchers followed more than 1,500 pregnant women diagnosed with COVID-19 who received care from Parkland Health and Hospital System in Dallas County, one of the nation’s busiest for deliveries. After the emergence of the Delta variant, the number of pregnant women hospitalized with COVID-19 more than doubled over the previous year.

And 82 pregnant women went on to develop severe or critical COVID, they report in their study, published online in the American Journal of Obstetrics and Gynecology. All but 1 of these patients were unvaccinated, 10 needed a ventilator, and two died.

The proportion of cases that were critical was about 5% in 2020. However, in April 2021, even though the number of total cases remained low, the number of severe illnesses started to rise. After the Delta variant became dominant, both the number and severity of cases increased, and after August 2021, more than 25% of pregnant people diagnosed with COVID-19 required hospitalization.
 

Hospitalizations Double

“We need to focus and really act urgently to recommend vaccination in pregnancy because that is the primary prevention tool that we have,” says Dr. Adhikari. “We do not have a proven cure for this illness, and that is important to know.”

These findings, which focus on a vulnerable population, are especially important given the elevated prevalence of COVID-19 in pregnant people of lower economic status, said Lissette Tanner, MD, MPH, from Emory University in Atlanta, who was not involved with the study.

“There are higher rates of hospitalization and death among Black, Hispanic, and Native American communities,” she reported. “It is essential to know how the virus is affecting those most affected and often most disadvantaged to deal with the pandemic.”

Vaccination rates are low in this population; just 19.2% of pregnant women receive at least one dose during pregnancy, according to the CDC. But pregnancy confers a higher risk for severe COVID-19 illness and for adverse outcomes, such as preterm birth and stillbirth.

Of the 665 people in the study cohort who were pregnant or had given birth when the vaccines were available, only 21.4% received at least one dose of a COVID-19 vaccine.

Given the increased risk for COVID-19 during pregnancy, the American College of Obstetricians and Gynecologists, the Society for Maternal-Fetal Medicine, and the CDC recommend vaccination for people who are pregnant, breastfeeding, or trying to get pregnant.

According to ACOG, pregnant women who are fully vaccinated can follow the same guidelines as everyone else who is fully vaccinated; however, to prevent breakthrough infections, they might want to continue wearing a mask. ACOG also recommends that those not fully vaccinated follow physical-distancing guidelines and limit contact with people as much as possible to avoid infection.

The benefits of Pfizer’s COVID-19 vaccine for children ages 5 to 11 outweigh its risks, according to an independent panel of vaccine experts that advises the Food and Drug Administration (FDA).
 

Seventeen of the 18 members of the Vaccines and Related Biological Products Advisory Committee (VRBPAC) on Oct. 26 voted to recommend the 10-microgram shot for kids, which is one-third the dose given to adults.

One member, Michael Kurilla, MD, director of the division of clinical innovation at the National Institutes of Health, Bethesda, Md., abstained from voting.

If the FDA follows the recommendation, as it typically does, and issues an Emergency Use Authorization for the vaccine, the shots could be available within days.

After the FDA’s final decision, the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices will meet to make specific recommendations for its use. The CDC committee must stick closely to the conditions for use spelled out in the EUA, so their recommendations are likely to be similar to those made by the FDA. Their next meeting is scheduled for Nov. 2 and 3.

In the end, some on the panel felt uneasy with their decision.

“I voted yes primarily because I wanted to make sure that children who really need this vaccine, the Black and brown children of our country, get the vaccine,” said James Hildreth, MD, PhD, president and CEO of Meharry Medical College in Nashville.

“But to be honest, the best way to protect the health of some children will be to do nothing because they will be just fine,” he said.

Others said they were surprised by how difficult the decision had been.

“This is a much tougher one than we had expected going into it,” said committee member Eric Rubin, MD, editor and chief of the New England Journal of Medicine, during the FDA advisory committee’s meeting.

Ahead of the vote, the committee heard presentations outlining the expected benefits of vaccinating children along with potential risks.

“Children have been greatly impacted by the pandemic,” said Fiona Havers, MD, a medical officer with the CDC in Atlanta who reviewed the epidemiology of COVID-19 in kids.

In the second year of the pandemic, as more seniors have been vaccinated against the virus, COVID cases have largely shifted from older to younger age groups.

So far, there have been more than 1.9 million COVID-19 cases in children ages 5 through 11 in the United States.. Cases in kids saw a big jump in July and August with summer travel, schools reopening, and the dominance of the Delta variant.

And those are just the cases reported to the CDC. Regular testing of anonymous blood samples collected at sites across the United States indicates that 6 times as many kids have had COVID than what is reflected in official counts.

Last winter, blood sample testing showed about 13% of children had antibodies against the virus, suggesting they’d been infected. By this summer, that number had risen to 42%.

That figure clearly made an impression on many members of the committee who asked the FDA’s vaccine reviewers if they had tried to account for immunity from past infections in their modeling. They had not.

Some felt that even with a highly effective vaccine — new data presented by Pfizer showed the children’s dose was 90% effective at preventing symptomatic infections in kids — caution was warranted as much is still unknown about myocarditis, a rare side effect of the mRNA vaccines.

Myocarditis has been more common in younger age groups. It usually goes away over time but requires hospital care. It’s not known if myocarditis could have lingering effects for those who experience it.

There were no cases of myocarditis seen in Pfizer’s studies of the vaccine in children, and no other serious events were seen. Vaccine side effects reported in the Pfizer studies were mostly mild and included fatigue, headache, and pain at the injection site.

“We think we have optimized the immune response and minimized our reactions,” said William Gruber, MD, senior vice president vaccine research and clinical development at Pfizer.

But the studies didn’t include enough participants to pick up rare, but serious adverse events like myocarditis.

“We’re worried about a side effect that we can’t measure yet, but it’s probably real, and we see a benefit that isn’t the same as it is in older age groups,” said Dr. Rubin.

Benefits vs. risks

FDA modeled the benefits and risks for children under a variety of scenarios. The benefits of the vaccines to children very much depend on the amount of transmission in the community.

When transmission is high, the benefits to children — in terms of infections, hospitalizations, ICU admissions — clearly outweigh its risks.

But when COVID-19 rates are low in the community, as they were in June, FDA analysts predicted the vaccines might send more children to the hospital for myocarditis than the virus would.

The FDA noted that kids who are hospitalized for myocarditis tend not to be as ill as children with COVID-19, however.

“If the trends continue the way they are going, the emergency for children is not what we might think it would be. That was my concern,” Dr. Hildreth said.

But others warned against complacency.

“Thinking that this is going to be the end of the wave permanently may be a little overly optimistic,” said committee chairman Arnold Monto, MD, a professor of public health and epidemiology at the University of Michigan, Ann Arbor.

The majority of COVID-19 cases in children are mild. Only about 1% of kids are hospitalized for their infections, according to CDC data. But the rates of hospitalizations in kids are about 3 times higher for people of color — including Blacks, Hispanics, and Native Americans, as compared to Whites and Asian Americans.

Since the start of the pandemic, 94 children ages 5 to 11 have died, making it the eighth leading cause of death for kids this age last year.

More than 5,200 children have developed a delayed complication from their infections called Multi-System Inflammatory Syndrome (MIS-C).

MIS-C can be severe and require hospital care and can lead to myocarditis. Children ages 5 to 11 are the age group at greatest risk for this complication.

Kids can also get long COVID. There’s not a lot of data on how often this happens, though it appears to be less frequent in children than in adults.

But a survey in the United Kingdom found that 7%-8% of kids have symptoms from their infections that last longer than 12 weeks, Dr. Havers said. Symptoms that can linger for kids include fatigue, cough, muscle and joint pain, headaches, and insomnia.

More than 1 million children have been impacted by school closures so far this year, and quarantines have had lasting impacts on learning, social development, and mental health.

Even though kids aren’t usually COVID superspreaders, they can still pass the infection on to others.

“What is clear is that secondary transmission from children, both to other children and to adults, does occur,” Dr. Havers said.

For that reason, they can continue the spread of the virus and give it opportunities to mutate and become more dangerous.

Safety monitoring to continue

Some committee members referenced thousands of letters they had received within the past few days urging them to vote against the vaccine.

Jay Portnoy, MD, a professor of pediatrics at Children’s Mercy Hospital in Kansas City, Mo., said he had personally received about 4,000 emails.

“But I feel like I need to also represent the consumers, the parents that I see every day in the clinic who are terrified of sending their children to school because they’re not protected against COVID,” he said, explaining his vote to recommend authorization.

“Our kids are going to be dealing with this virus for many years to come. It’s going to come repeatedly. Getting this vaccine is just the first step that they can take to protect themselves from having bad outcomes,” Dr. Portnoy said.

Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, reminded members of the committee that there were several government surveillance systems in place to catch any potential safety issues in near real time.

“I really appreciate very much the concern here. The safety monitoring of this vaccine will continue,” Dr. Marks said. “I do view this as one of our greatest responsibilities.”

“I really am so grateful that we had this discussion and voted to approve,” said Capt. Amanda Cohn, MD, chief medical officer at the National Center for Immunization and Respiratory Diseases.

“I think the benefits in this age group really are super important even if they are lower than for other age groups.”

The U.S. Centers for Disease Control and Prevention Advisory Committee of Immunization Practices has voted to recommend Shingrix (zoster vaccine recombinant, adjuvanted) for the prevention of shingles in immunodeficient or immunosuppressed adults aged 19 or older. The recommendation was approved Oct. 20 by a unanimous vote.

Shingles is a reactivation of varicella zoster virus (VZV), the virus that causes chickenpox. There are about 1 million cases of shingles in the United States every year, according to CDC estimates, and one in three Americans will develop shingles over their lifetime. While adults older than 50 are one of the most vulnerable groups to reinfection – with about 99% having been infected with VZV – a weakened immune system is another common risk factor.

The Food and Drug Administration originally approved Shingrix in 2017 for the prevention of shingles in adults over 50; in July of this year, the vaccine was approved for immunodeficient adults aged 18 or older. The approval and subsequent recommendation by ACIP were based on clinical studies of Shingrix in adults being treated for hematologic malignancies or those who had undergone an autologous hematopoietic stem cell transplant.

According to a press statement from the FDA, “Further safety and immunogenicity data were generated in adults who were, or were anticipated to be, immunodeficient or immunosuppressed due to known disease or therapy, including patients with HIV, solid tumors, and renal transplants.”

For adults with functional immune systems, Shingrix is administered in two doses, 2-6 months apart. For immunocompromised individuals, the second dose can be given 1-2 months after the first dose.

During the same meeting, ACIP also voted to recommend pneumococcal vaccines for routine use in adults older than 65 and in adults aged 19-64 with chronic conditions such as diabetes, chronic heart disease, chronic liver disease, and HIV, and disease risk factors like smoking and alcoholism. The recommendation only applies to those who have not received a pneumococcal conjugate vaccine or whose vaccination history is unknown. The recommendation states that qualifying adults should be vaccinated with the 15-valent pneumococcal conjugate vaccine Vaxneuvance followed by Pneumovax23, or a single dose of the 20-valent pneumococcal conjugate vaccine Prevnar 20.

These ACIP recommendations will now be sent to the directors of the CDC and the U.S. Department of Health & Human Services for review and approval. If approved, the recommendations are considered finalized and will be published in a future Morbidity and Mortality Weekly Report.

The White House says it has purchased enough of Pfizer’s COVID-19 vaccine to immunize all 28 million children in the United States who are between the ages of 5 and 12.

States were allowed to begin preordering the shots this week. But they can’t be delivered into kids’ arms until the FDA and CDC sign off. The shots could be available in early November.

“We know millions of parents have been waiting for COVID-19 vaccine for kids in this age group, and should the FDA and CDC authorize the vaccine, we will be ready to get shots in arms,” Jeff Zients, the White House COVID-19 response coordinator, said at a briefing Oct. 20.

Asked whether announcing plans to deliver a vaccine to children might put pressure on the agencies considering the evidence for their use, Mr. Zients defended the Biden administration’s plans.

“This is the right way to do things: To be operationally ready,” he said. Mr. Zients said they had learned a lesson from the prior administration.

“The decision was made by the FDA and CDC, and the operations weren’t ready. And that meant that adults at the time were not able to receive their vaccines as efficiently, equitably as possible. And this will enable us to be ready for kids,” he said.

Pfizer submitted data to the FDA in late September from its test of the vaccine in 2,200 children. The company said the shots had a favorable safety profile and generated “robust” antibody responses.

An FDA panel is scheduled to meet on Oct. 26 to consider Pfizer’s application. The CDC’s Advisory Committee on Immunization Practices will meet the following week, on Nov. 2 and 3.
 

Laying the groundwork

Doctors applauded the advance planning.

“Laying this advance groundwork, ensuring supply is available at physician practices, and that a patient’s own physician is available to answer questions, is critical to the continued success of this rollout,” Gerald Harmon, MD, president of the American Medical Association, said in a written statement.

The shots planned for children are 10 micrograms, a smaller dose than is given to adults. To be fully immunized, kids get two doses, spaced about 21 days apart. Vaccines for younger children are packaged in smaller vials and injected through smaller needles, too.

The vaccine for younger children will roll out slightly differently than it has for adults and teens. While adults mostly got their COVID-19 vaccines through pop-up mass vaccination sites, health departments, and other community locations, the strategy to get children immunized against COVID is centered on the offices of pediatricians and primary care doctors.

The White House says 25,000 doctors have already signed up to give the vaccines.

The vaccination campaign will get underway at a tough moment for pediatricians.

The voicemail message at Roswell Pediatrics Center in the suburbs north of Atlanta, for instance, warns parents to be patient.

“Due to the current, new COVID-19 surge, we are experiencing extremely high call volume, as well as suffering from the same staffing shortages that most businesses are having,” the message says, adding that they’re working around the clock to answer questions and return phone calls.

Jesse Hackell, MD, says he knows the feeling. He’s the chief operating officer of Pomona Pediatrics in Pomona, N.Y., and a spokesperson for the American Academy of Pediatrics.

“We’re swamped now by kids who get sent home from school because they sneezed once and they have to be cleared before they can go back to school,” he said. “We’re seeing kids who we don’t need to see in terms of the degree of illness because the school requires them to be cleared [of COVID-19].”

Dr. Hackell has been offering the vaccines to kids ages 12 and up since May. He’s planning to offer it to younger children too.

“Adding the vaccines to it is going to be a challenge, but you know we’ll get up to speed and we’ll make it happen,” he said, adding that pediatricians have done many large-scale vaccination campaigns, like those for the H1N1 influenza vaccine in 2009.

Dr. Hackell helped to draft a new policy in New York that will require COVID-19 vaccines for schoolchildren once they are granted full approval from the FDA. Other states may follow with their own vaccination requirements.

He said ultimately, vaccinating school-age children is going to make them safer, will help prevent the virus from mutating and spreading, and will help society as a whole get back to normal.

“We’re the vaccine experts in pediatrics. This is what we do. It’s a huge part of our practice like no other specialty. If we can’t get it right, how can anyone else be expected to?” he said.

While the U.S. Food and Drug Administration has yet to give the green light to COVID-19 vaccination for children who are under age 12, it is expected that approval will be granted. In anticipation of the FDA’s go-ahead, which is expected in the coming weeks, a new “rapid expert consultation” has identified “actionable guidance” that state and local decision-makers can use to communicate with the public. The goal is to build confidence in and promote the uptake of COVID-19 vaccines, especially for parents who are contemplating vaccinating their children.

They note that key factors in decision-making concern vaccine side effects, the efficacy of the vaccine in children, availability of research in their child’s age group, research conducted by the parents themselves, and recommendations by the child’s health care provider.

“One of the reasons that the COVID vaccine only became available for children 12 and over months after it was approved for adults is that it takes time and many, many trial participants who are closely monitored before the vaccine ever reaches the general public,” said Nusheen Ameenuddin, MD, MPH, MPA, an assistant professor of pediatrics at the Mayo Clinic, Rochester, Minn. “We continue to talk to parents about the fact that the vaccines have been very safe and effective in this group, and even though people are concerned about side effects, they are much milder and less frequent than the effects of the disease itself.”

Dr. Ameenuddin noted that the lack of data in this age group can be concerning for parents. “It’s not like other vaccines which have been available for a long time, and the clinical trial data are still limited for this age group,” she said. “But I think the main point that practitioners need to emphasize is that, even though the vaccine is new, the science for this vaccine has been around for about a decade.”

The unique circumstances of a pandemic, she pointed out, allowed for important information about effectiveness, safety, and side effects to be obtained more quickly from clinical trial data.

“We have really good evidence for kids 12 and over, about safety and effectiveness, and even though children are not small adults and have their own unique physiology, this has provided a good starting point to suggest that kids slightly younger will also respond well to the vaccines,” said Dr. Ameenuddin, who is also chair of the American Academy of Pediatrics Council on Communications and Media. “As we learn more, we can start gathering more information about even younger kids to ensure that the right dosage and spacing of vaccines can provide maximum vaccine effectiveness and protection from disease.”

The guidance was published Oct. 13 by the National Academies of Sciences, Engineering, and Medicine.

The rapid expert consultation was produced through the Societal Experts Action Network, an activity of the National Academies that is sponsored by the NASEM and the Alfred P. Sloan Foundation. The goal of SEAN is to connect researchers in the social, behavioral, and economic sciences with decision-makers to respond to policy questions related to the COVID-19 pandemic.

In their expert consultation, the authors emphasize that vaccination is critical for decreasing transmission and controlling infection, as well as limiting the emergence of future serious variants. As of Oct. 3, 2021, about 65% of the U.S. population had received at least one dose of the vaccine, and the rate has begun to lag in many areas of the country. There are a variety of reasons for vaccine hesitancy, they note, including perception of low risks from COVID-19 or of high risks from COVID-19 vaccines, exposure to media, political agendas, lack of confidence in science, and distrust of the medical establishment. The Pfizer/BioNTech vaccine is currently authorized for emergency use for individuals 12 years of age and older and fully approved for those aged 16 and older, while the Moderna and the Johnson & Johnson vaccines are authorized for emergency use for those 18 years of age and older.

Many children between the ages of 12 and 17 have not been vaccinated, and the major concerns reported by parents include not knowing enough about the long-term effects of the COVID-19 vaccine in children (88%), concerns about children experiencing serious side effects (79%), and concerns that the COVID-19 vaccine might negatively affect future fertility (73%).

The National Academies have previously released two other “rapid expert consultations” which have addressed building vaccine confidence, and both reports provide key strategies for communicating information about COVID-19 vaccines. In this paper, the focus was on communicating with parents to gain confidence in the vaccine and address concerns.
 

Key points

The key strategies highlighted for communicating with parents include the following:

• Emphasizing safety and efficacy: Parents should be informed about the ongoing research and clinical trials that will answer more questions about the vaccine and that there is continued monitoring for any safety risks. Pointing to the safety data from the clinical trials for 12- to 17-year-olds, and the lack of serious adverse events from the vaccine in this age group may help alleviate concerns.
• CalibriEncouraging parents to talk with a primary care provider: Research shows that parents trust family physicians and other health care practitioners to provide them with accurate information about vaccines. Local, state, and national leaders can provide messaging templates and other resources to health care professionals who are engaged in these conversations.
• Leveraging social networks to influence parents’ vaccination decisions: Parents are influenced by their social network connections. It is important to engage these networks, especially with members of their community who are considered trustworthy and influential. Social networks may also be very diverse, and include family members, friends, coworkers, social media, and members of their religious community.

While the guidance states that different groups of parents will require different messaging, they suggest that communication can begin with a focus on the things that vaccination can accomplish. In addition to preventing infection with COVID-19, it will allow children to attend school in person and participate in extracurricular activities such as sports, without risking their health. “One thing I’ve learned over several years of working with vaccine-hesitant parents is that you have to tailor each approach to the individual,” said Dr. Ameenuddin. “Different people have different concerns, and first and foremost, it’s important to listen.”

For some parents, emphasizing that the more people that can be vaccinated and the sooner it can be done, the sooner everyone can return to a normal life is a good approach, she added. “I think it’s important to emphasize both the individual and communal benefits of vaccines, but that won’t necessarily reach every person with concerns. I think it’s important to find out what is most important to individuals and work from there to find a way to connect with that family to encourage vaccination.”

“One of the reasons that the COVID vaccine only became available for children 12 and over months after it was approved for adults is that it takes time and many, many trial participants who are closely monitored before the vaccine ever reaches the general public,” said Nusheen Ameenuddin, MD, MPH, MPA, an assistant professor of pediatrics at the Mayo Clinic, Rochester, Minn. “We continue to talk to parents about the fact that the vaccines have been very safe and effective in this group, and even though people are concerned about side effects, they are much milder and less frequent than the effects of the disease itself.”

Dr. Ameenuddin noted that the lack of data in this age group can be concerning for parents. “It’s not like other vaccines which have been available for a long time, and the clinical trial data are still limited for this age group,” she said. “But I think the main point that practitioners need to emphasize is that, even though the vaccine is new, the science for this vaccine has been around for about a decade.”

The unique circumstances of a pandemic, she pointed out, allowed for important information about effectiveness, safety, and side effects to be obtained more quickly from clinical trial data.

“We have really good evidence for kids 12 and over, about safety and effectiveness, and even though children are not small adults and have their own unique physiology, this has provided a good starting point to suggest that kids slightly younger will also respond well to the vaccines,” said Dr. Ameenuddin, who is also chair of the American Academy of Pediatrics Council on Communications and Media. “As we learn more, we can start gathering more information about even younger kids to ensure that the right dosage and spacing of vaccines can provide maximum vaccine effectiveness and protection from disease.”

The guidance was published Oct. 13 by the National Academies of Sciences, Engineering, and Medicine.

The rapid expert consultation was produced through the Societal Experts Action Network, an activity of the National Academies that is sponsored by the NASEM and the Alfred P. Sloan Foundation. The goal of SEAN is to connect researchers in the social, behavioral, and economic sciences with decision-makers to respond to policy questions related to the COVID-19 pandemic.

In their expert consultation, the authors emphasize that vaccination is critical for decreasing transmission and controlling infection, as well as limiting the emergence of future serious variants. As of Oct. 3, 2021, about 65% of the U.S. population had received at least one dose of the vaccine, and the rate has begun to lag in many areas of the country. There are a variety of reasons for vaccine hesitancy, they note, including perception of low risks from COVID-19 or of high risks from COVID-19 vaccines, exposure to media, political agendas, lack of confidence in science, and distrust of the medical establishment. The Pfizer/BioNTech vaccine is currently authorized for emergency use for individuals 12 years of age and older and fully approved for those aged 16 and older, while the Moderna and the Johnson & Johnson vaccines are authorized for emergency use for those 18 years of age and older.

Many children between the ages of 12 and 17 have not been vaccinated, and the major concerns reported by parents include not knowing enough about the long-term effects of the COVID-19 vaccine in children (88%), concerns about children experiencing serious side effects (79%), and concerns that the COVID-19 vaccine might negatively affect future fertility (73%).

The National Academies have previously released two other “rapid expert consultations” which have addressed building vaccine confidence, and both reports provide key strategies for communicating information about COVID-19 vaccines. In this paper, the focus was on communicating with parents to gain confidence in the vaccine and address concerns.
 

Key points

The key strategies highlighted for communicating with parents include the following:

• Emphasizing safety and efficacy: Parents should be informed about the ongoing research and clinical trials that will answer more questions about the vaccine and that there is continued monitoring for any safety risks. Pointing to the safety data from the clinical trials for 12- to 17-year-olds, and the lack of serious adverse events from the vaccine in this age group may help alleviate concerns.
• CalibriEncouraging parents to talk with a primary care provider: Research shows that parents trust family physicians and other health care practitioners to provide them with accurate information about vaccines. Local, state, and national leaders can provide messaging templates and other resources to health care professionals who are engaged in these conversations.
• Leveraging social networks to influence parents’ vaccination decisions: Parents are influenced by their social network connections. It is important to engage these networks, especially with members of their community who are considered trustworthy and influential. Social networks may also be very diverse, and include family members, friends, coworkers, social media, and members of their religious community.

While the guidance states that different groups of parents will require different messaging, they suggest that communication can begin with a focus on the things that vaccination can accomplish. In addition to preventing infection with COVID-19, it will allow children to attend school in person and participate in extracurricular activities such as sports, without risking their health. “One thing I’ve learned over several years of working with vaccine-hesitant parents is that you have to tailor each approach to the individual,” said Dr. Ameenuddin. “Different people have different concerns, and first and foremost, it’s important to listen.”

For some parents, emphasizing that the more people that can be vaccinated and the sooner it can be done, the sooner everyone can return to a normal life is a good approach, she added. “I think it’s important to emphasize both the individual and communal benefits of vaccines, but that won’t necessarily reach every person with concerns. I think it’s important to find out what is most important to individuals and work from there to find a way to connect with that family to encourage vaccination.”

States can preorder COVID-19 vaccine doses for younger children this week as they begin to set up vaccination campaigns for ages 5-11.

Vaccine advisory groups for the FDA and CDC are scheduled to discuss and approve the Pfizer shot for kids in the next three weeks. To help states and cities prepare for the rollout, the CDC issued guidance on how to set up expanded vaccination programs.

Immunization program managers can begin ordering doses on Wednesday, according to the guidance. The vials won’t be delivered until the FDA and CDC authorize the shot, but registering now will help federal officials ship doses quickly once they’re available.

Pharmacies in every state will be able to give COVID-19 shots to children, but they can only use doses that are prepared specifically for children. Ages 5-11 will need a 10-microgram dose, which is one-third of the dose administered to ages 12 and older. The guidance warns that doctors should not try to split up or fraction the adult doses.

The CDC guidance also recommends that pediatricians and family practice doctors should serve as primary places to give shots to kids. The document mentions other options, such as vaccination clinics at schools, but doesn’t endorse them as the first choice for vaccinating kids.

The CDC hasn’t yet addressed questions around whether kids should be required to get vaccinated to attend school. The decision will likely be left to state and city officials.

Federal health officials aren’t yet sure how many parents and guardians will seek shots for their younger kids right away, the AP reported. Demand may be high at first for some families, but it may not be as high as when shots first became available for adults, Marcus Plescia, MD, chief medical officer of the Association of State and Territorial Health Officials, told The Associated Press.

“We’re going to have potentially a very busy, and perhaps modestly chaotic time,” he said.

When vaccines were first authorized for adults, hospitals and pharmacies received priority for ordering shots. Some doctors felt left out. This time, however, the CDC has said that pediatricians will receive higher priority and be able to receive shipments quickly.

As the vaccine rollout begins, health officials should consider logistical concerns to address racial and economic disparities for younger kids, Richard Besser, MD, president and CEO of the Robert Wood Johnson Foundation and a former acting director of the CDC, told the AP.

If parents or guardians can’t leave work to take their kids to a pharmacy or doctor’s office, for instance, their kids may not receive a shot quickly – or at all.

“It’s really important that we recognize the barriers to vaccinations,” he said.

The Food and Drug Administration has approved the Flucelvax quadrivalent vaccine for use in children aged 6 months and older, according to a statement from manufacturer Seqirus.

“This approval officially allows all eligible Americans to receive a cell-based influenza vaccine, increasing the potential for greater vaccine effectiveness,” according to the company.

The Centers for Disease Control and Prevention currently recommends annual influenza vaccination for all individuals aged 6 months and older without contraindications.

Flucelvax is manufactured using a cell-based process that yields a more precise match to the WHO-selected influenza strains for a given year. This process avoids the variation associated with traditional egg-based vaccines, and offers the potential for greater vaccine effectiveness, according to the company.

The approval was based in part on data from a phase 3 randomized, controlled noninferiority study of children aged 6-47 months. The data are the first for a cell-based flu vaccine in this age group, and were presented at the Pediatric Academic Societies meeting in 2021.

In the immunogenicity study of children aged 6 months through 3 years, described in the package insert, 1,597 children received Flucelvax quadrivalent and 805 received a control quadrivalent vaccine. After 28 days, Flucelvax showed noninferiority to the control quadrivalent against four influenza strains.

The most common side effects with Flucelvax quadrivalent vaccine overall are pain, redness, swelling, or a hardened area at the injection site, headache, low energy, muscle aches, and malaise. Additional side effects reported in children include tenderness or bruising at the injection site, sleepiness, diarrhea, changes in eating habits, and irritability. The vaccine is contraindicated for individuals with allergies to any of its ingredients.

Additional efficacy data on Flucelvax for children and adolescents aged 2-18 years were recently published in The New England Journal of Medicine.

Patients who are being treated with Janus kinase (JAK) inhibitors overall show a high immune response rate to COVID-19 vaccination, one that matches the rates seen in patients on other immunosuppressants, a new study has found.

The patients taking a JAK inhibitor who are most at risk of a diminished response may be those on upadacitinib (Rinvoq) and anyone 65 years or older, wrote Raphaèle Seror, MD, PhD, of Paris-Saclay (France) University and coauthors. The study was published in The Lancet Rheumatology.

To gauge the effectiveness of COVID-19 vaccines in this subset of immunosuppressed patients, the researchers analyzed 113 participants in the MAJIK-SFR Registry, a multicenter study of French patients with rheumatoid or psoriatic arthritis. The participants were treated at 13 centers throughout France; their mean age was 61.8 years (standard deviation, 12.5), and 72% were female. A total of 56 were taking baricitinib (Olumiant), 30 were taking tofacitinib (Xeljanz), and 27 were taking upadacitinib.

Serologic assessment was performed an average of 8.7 weeks (SD, 5.2) after the last dose of vaccine. The overall response rate – defined as the proportion of patients with detectable anti-spike antibodies per manufacturer’s cutoff values – was 88% (100 of 113). The nonresponse rate was higher with upadacitinib (7 of 27 patients, 26%) than with baricitinib (5 of 56, 9%) or tofacitinib (1 of 30, 3%). The only nonresponders who were not age 65 or older were four of the seven who received upadacitinib. The interval between the last vaccine dose and serologic assessment was somewhat longer in nonresponders (11.3 weeks) than in responders (8.3 weeks).

Earlier this year, the American College of Rheumatology recommended withholding JAK inhibitors for 1 week after each vaccine dose because of “concern related to the effects of this medication class on interferon signaling that may result in a diminished vaccine response Only two patients in the study had treatment with JAK inhibitors stopped before or after vaccination.

Questions about antibody levels remain difficult to answer

“This study does further confirm a big point,” said Alfred Kim, MD, PhD, of Washington University, St. Louis, in an interview. “Most people on any sort of immunosuppression, with rare exceptions, can mount responses to COVID-19 vaccination.”

“What level of response is going to be sufficient, of course, is not clear,” he added. “Even though most people generate responses, at the population level those responses seem lower than those in nonimmunosuppressed people. Particularly for those on upadacitinib, which is lower than patients on the other JAK inhibitors. Is that problematic? We don’t know yet.”

Dr. Kim, who was part of a separate, earlier study that assessed vaccine response in patients with chronic inflammatory disease who were being treated with immunosuppressive medications, noted that many of the questions patients are asking about their antibody levels cannot yet be answered.

“It’s kind of the Wild West of serologic testing out there right now,” he said. “Even though we’re recommending that people still don’t check their antibody levels because their results are largely inactionable, everyone is still getting them anyway. But each of these tests are slightly different, and the results and the interpretation are further clouded because of those slight performance differences between each platform.”

Dr. Kim highlighted the number of different tests as one of this study’s notable limitations: 11 different assays were used to determine patients’ immune responses. “The authors made the argument that these tests are FDA approved, and that’s true, but that doesn’t necessarily mean much. Approval does translate to technical reliability but not to comparisons between the tests.”

As for next steps, both the authors and Dr. Kim recognized the need for a prospective trial. “To do a vaccine effectiveness–type study and show clinical protection against either infection or hospitalization – those are going to take a while, simply because of the nature of how many people you need for each of these studies,” he said. “Time will tell whether or not the data that are being presented here will translate literally into protective outcomes downstream.”

The MAJIK Registry is supported by the French Rheumatology Society. The authors acknowledged numerous potential conflicts of interest, including receiving consulting fees, research support, and honoraria from various pharmaceutical companies.

A U.S. Food and Drug Administration (FDA) advisory committee on Oct. 15 voted 19-0 to authorize second doses of the Johnson & Johnson COVID-19 vaccine in an effort to boost immunity. It was the second vote in as many days to back a change to a COVID vaccine timeline.
 

Johnson & Johnson

In its vote, the committee said that boosters could be offered to people as young as age 18. However, it is not clear that everyone who got a Johnson & Johnson vaccine needs to get a second dose. The same panel voted Oct. 14 to recommend booster shots for the Moderna vaccine, but for a narrower group of people.

It will be up to a Centers for Disease Control and Prevention (CDC) panel to make more specific recommendations for who might need another shot. The CDC’s Advisory Committee on Immunization Practices is scheduled to meet next Oct. 21 to discuss issues related to COVID-19 vaccines.

Studies of the effectiveness of the Johnson & Johnson vaccine in the real world show that its protection — while good — has not been as strong as that of the mRNA vaccines made by Pfizer and Moderna, which are given as part of a two-dose series.

In the end, the members of the FDA’s Vaccines and Related Biological Products Advisory Committee said they felt that the company hadn’t made a case for calling their second shot a booster, but had shown enough data to suggest that everyone over the age of 18 should consider getting two shots of the Johnson & Johnson vaccine as a matter of course.

This is an especially important issue for adults over the age of 50. A recent study in the New England Journal of Medicine found that older adults who got the Johnson & Johnson vaccine were less protected against infection and hospitalization than those who got mRNA vaccines.
 

Limited data

The company presented data from six studies to the FDA panel in support of a second dose that were limited. The only study looking at second doses after 6 months included just 17 people.

These studies did show that a second dose substantially increased levels of neutralizing antibodies, which are the body’s first line of protection against COVID-19 infection.

But the company turned this data over to the FDA so recently that agency scientists repeatedly stressed during the meeting that they did not have ample time to follow their normal process of independently verifying the data and following up with their own analysis of the study results.

Peter Marks, MD, director of the FDA’s Center for Biologics Evaluation and Research, said it would have taken months to complete that rigorous level of review.

Instead, in the interest of urgency, the FDA said it had tried to bring some clarity to the tangle of study results presented that included three dosing schedules and different measures of effectiveness.

“Here’s how this strikes me,” said committee member Paul Offit, MD, a professor of pediatrics and infectious disease at Children’s Hospital of Philadelphia. “I think this vaccine was always a two-dose vaccine. I think it’s better as a two-dose vaccine. I think it would be hard to recommend this as a single-dose vaccine at this point.”

“As far as I’m concerned, it was always going to be necessary for J&J recipients to get a second shot,” said James Hildreth, MD, PhD, president and CEO of Meharry Medical College in Nashville.

Archana Chatterjee, MD, PhD, dean of the Chicago Medical School at Rosalind Franklin University of Medicine and Science, said she had changed her vote during the course of the meeting.

She said that, based on the very limited safety and effectiveness data presented to the committee, she was prepared to vote against the idea of offering second doses of Johnson & Johnson shots.

But after considering the 15 million people who have been vaccinated with a single dose and studies that have suggested that close to 5 million older adults may still be at risk for hospitalization because they’ve just had one shot, “This is still a public health imperative,” she said.

“I’m in agreement with most of my colleagues that this second dose, booster, whatever you want to call it, is necessary in these individuals to boost up their immunity back into the 90-plus percentile range,” Dr. Chatterjee said.

Who needs a second dose?

On Oct. 14, the committee heard an update on data from Israel, which saw a wave of severe breakthrough infections during the Delta wave.

COVID-19 cases are falling rapidly there after the country widely deployed booster doses of the Pfizer vaccine.

The FDA’s Dr. Marks said Oct. 15 that the agency was leaning toward creating greater flexibility in the emergency use authorizations (EUAs) for the Johnson & Johnson and Moderna vaccines so that boosters could be more widely deployed in the United States too.

The FDA panel on Oct. 14 voted to authorize a 50-milligram dose of Moderna’s vaccine — half the dose used in the primary series of shots — to boost immunity at least 6 months after the second dose.

Those who might need a Moderna booster are the same groups who’ve gotten a green light for third Pfizer doses, including people over 65, adults at higher risk for severe COVID-19, and those who are at higher risk because of where they live or work.

The FDA asked the committee on Oct. 15 to discuss whether boosters should be offered to younger adults, even those without underlying health conditions.

“We’re concerned that what was seen in Israel could be seen here,” Dr. Marks said. “We don’t want to have a wave of severe COVID-19 before we deploy boosters.”
 

Trying to avoid confusion

Some members of the committee cautioned Dr. Marks to be careful when expanding the EUAs, because it could confuse people.

“When we say immunity is waning, what are the implications of that?” said Michael Kurilla, MD, PhD, director of the division of clinical innovation at the National Institutes of Health.

Overall, data show that all the vaccines currently being used in the United States — including Johnson & Johnson — remain highly effective for preventing severe outcomes from COVID-19, like hospitalization and death.

Booster doses could prevent more people from even getting mild or moderate symptoms from “breakthrough” COVID-19 cases, which began to rise during the recent Delta surge. The additional doses are also expected to prevent severe outcomes like hospitalization in older adults and those with underlying health conditions.

“I think we need to be clear when we say waning immunity and we need to do something about that, I think we need to be clear what we’re really targeting [with boosters] in terms of clinical impact we expect to have,” Dr. Kurilla said.

Others pointed out that preventing even mild-to-moderate infections was a worthy goal, especially considering the implications of long-haul COVID-19.

“COVID does have tremendous downstream effects, even in those who are not hospitalized. Whenever we can prevent significant morbidity in a population, there are advantages to that,” said Steven Pergam, MD, MPH, medical director of infection prevention at the Seattle Cancer Care Alliance.

“I’d really be in the camp that would be moving towards a younger age range for allowing boosters,” he said.

A U.S. Food and Drug Administration (FDA) advisory committee on Oct. 15 voted 19-0 to authorize second doses of the Johnson & Johnson COVID-19 vaccine in an effort to boost immunity. It was the second vote in as many days to back a change to a COVID vaccine timeline.
 

Johnson & Johnson

In its vote, the committee said that boosters could be offered to people as young as age 18. However, it is not clear that everyone who got a Johnson & Johnson vaccine needs to get a second dose. The same panel voted Oct. 14 to recommend booster shots for the Moderna vaccine, but for a narrower group of people.

It will be up to a Centers for Disease Control and Prevention (CDC) panel to make more specific recommendations for who might need another shot. The CDC’s Advisory Committee on Immunization Practices is scheduled to meet next Oct. 21 to discuss issues related to COVID-19 vaccines.

Studies of the effectiveness of the Johnson & Johnson vaccine in the real world show that its protection — while good — has not been as strong as that of the mRNA vaccines made by Pfizer and Moderna, which are given as part of a two-dose series.

In the end, the members of the FDA’s Vaccines and Related Biological Products Advisory Committee said they felt that the company hadn’t made a case for calling their second shot a booster, but had shown enough data to suggest that everyone over the age of 18 should consider getting two shots of the Johnson & Johnson vaccine as a matter of course.

This is an especially important issue for adults over the age of 50. A recent study in the New England Journal of Medicine found that older adults who got the Johnson & Johnson vaccine were less protected against infection and hospitalization than those who got mRNA vaccines.
 

Limited data

The company presented data from six studies to the FDA panel in support of a second dose that were limited. The only study looking at second doses after 6 months included just 17 people.

These studies did show that a second dose substantially increased levels of neutralizing antibodies, which are the body’s first line of protection against COVID-19 infection.

But the company turned this data over to the FDA so recently that agency scientists repeatedly stressed during the meeting that they did not have ample time to follow their normal process of independently verifying the data and following up with their own analysis of the study results.

Peter Marks, MD, director of the FDA’s Center for Biologics Evaluation and Research, said it would have taken months to complete that rigorous level of review.

Instead, in the interest of urgency, the FDA said it had tried to bring some clarity to the tangle of study results presented that included three dosing schedules and different measures of effectiveness.

“Here’s how this strikes me,” said committee member Paul Offit, MD, a professor of pediatrics and infectious disease at Children’s Hospital of Philadelphia. “I think this vaccine was always a two-dose vaccine.

This article was updated on 10/18/21. A version of this article first appeared on Medscape.com.

A new U.S. government study shows it isn’t risky and may even be a good idea to mix, rather than match, COVID-19 vaccines when getting a booster dose.

The study also shows mixing different kinds of vaccines appears to spur the body to make higher levels of virus-blocking antibodies than they would have gotten by boosting with a dose of the vaccine the person already had.

If regulators endorse the study findings, it should make getting a COVID-19 booster as easy as getting a yearly influenza vaccine.

“Currently when you go to do your flu shot nobody asks you what kind you had last year. Nobody cares what you had last year. And we were hoping that that was the same — that we would be able to boost regardless of what you had [previously],” said the study’s senior author, John Beigel, MD, who is associate director for clinical research in the division of microbiology and infectious diseases at the National Institutes of Health.

“But we needed to have the data,” he said.

Studies have suggested that higher antibody levels translate into better protection against disease, though the exact level that confers protection is not yet known.

“The antibody responses are so much higher [with mix and match], it’s really impressive,” said William Schaffner, MD, an infectious disease specialist at Vanderbilt University in Nashville, who was not involved in the study.

Dr. Shaffner said if the U.S. Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) sign off on the approach, he would especially recommend that people who got the Johnson & Johnson vaccine follow up with a dose of an mRNA vaccine from Pfizer or Moderna.

“It is a broader stimulation of the immune system, and I think that broader stimulation is advantageous,” he said.

Minimal side effects

The preprint study was published late Oct. 13 in medRxiv ahead of peer review, just before a slate of meetings involving vaccine experts that advise the FDA and CDC. 

These experts are tasked with trying to figure out whether additional shots of Moderna and Johnson & Johnson vaccines are safe and effective for boosting immunity against COVID-19.

The FDA’s panel is the Vaccines and Related Biological Products Advisory Committee (VRBPAC), and the CDC’s panel is the Advisory Committee on Immunization Practices (ACIP). 

During the pandemic, they have been meeting almost in lock step to tackle important vaccine-related questions.

“We got this data out because we knew VRBPAC was coming and we knew ACIP was going to grapple with these issues,” Dr. Beigel said.

He noted that these are just the first results. The study will continue for a year, and the researchers aim to deeply characterize the breadth and depth of the immune response to all nine of the different vaccine combinations included in the study.

The study included 458 participants at 10 study sites around the country who had been fully vaccinated with one of the three COVID-19 vaccines authorized for use in the United States: Moderna, Johnson & Johnson, or Pfizer-BioNTech. 

About 150 study participants were recruited from each group. Everyone in the study had finished their primary series at least 12 weeks before starting the study. None had a prior SARS-CoV-2 infection.

About 50 participants from each vaccine group were randomly assigned to get a third (booster) dose of either the same vaccine as the one they had already received, or a different vaccine, creating nine possible combinations of shots.

About half of study participants reported mild side effects — including pain at the injection site, fatigue, headache, and muscle aches.

Two study participants had serious medical problems during the study, but they were judged to be unrelated to vaccination. One study participant experienced kidney failure after their muscles broke down following a fall. The other experienced cholecystitis, or an inflamed gallbladder. 

Up to 1 month after the booster shots, no other serious adverse events were seen.

The study didn’t look at whether people got COVID-19, so it’s not possible to say that they were better protected against disease after their boosters.

Increase in antibodies

But all the groups saw substantial increases in their antibody levels, which is thought to indicate that they were better protected.

Overall, groups that got the same vaccine as their primary series saw 4 to 20-fold increases in their antibody levels. Groups that got different shots than the ones in their primary series got 6 to 76 fold increases in their antibody levels.

People who had originally gotten a Johnson & Johnson vaccine saw far bigger increases in antibodies, and were more likely to see a protective rise in antibodies if they got a second dose of an mRNA vaccine.

Dr. Schaffner noted that European countries had already been mixing the vaccine doses this way, giving people who had received the AstraZeneca vaccine, which is similar to the Johnson & Johnson shot, another dose of an mRNA vaccine.

German Chancellor Angela Merkel received a Moderna vaccine for her second dose after an initial shot of the Oxford-AstraZeneca vaccines, for example.

No safety signals related to mixing vaccines has been seen in countries that routinely use the approach for their initial series.
