Three JAK inhibitors get boxed warnings, modified indications
The arthritis and ulcerative colitis medicine tofacitinib (Xeljanz, Xeljanz XR) poses an increased risk of serious cardiac events such as heart attack or stroke, cancer, blood clots, and death, the Food and Drug Administration announced Sept 1.
Manufacturers of this drug along with other Janus kinase (JAK) inhibitors baricitinib (Olumiant) and upadacitinib (Rinvoq) must update their boxed warnings to include information about these health risks. The FDA made the determination after new study data from Pfizer, which manufacturers Xeljanz, found an association between a lower dose of Xeljanz and increased risk of blood clots and death.
“Recommendations for healthcare professionals will include consideration of the benefits and risks for the individual patient prior to initiating or continuing therapy,” the agency stated.
The FDA is limiting all approved uses of these three medications to patients who have not responded well to tumor necrosis factor (TNF) blockers to ensure their benefits outweigh their risks. Tofacitinib is indicated for rheumatoid arthritis, psoriatic arthritis, ulcerative colitis, and polyarticular course juvenile idiopathic arthritis. Baricitinib and upadacitinib are approved only for RA. The FDA included baricitinib and upadacitinib in the warning because of the similar properties they share with tofacitinib, even though they haven’t been studied as extensively.
“We believe this update will bring important clarity for healthcare plans on the risk/benefit profile of Xeljanz, which is a medicine informed by more clinical data than any other JAK inhibitor,” Pfizer said in a statement.
Investigators for the ORAL Surveillance trial compared two doses of tofacitinib (5 mg twice daily and 10 mg twice daily) with TNF blockers in patients with rheumatoid arthritis who were aged 50 years or older with at least one additional cardiovascular risk factor.
For both dose regimens of tofacitinib, they found an increased risk of major adverse cardiovascular events, malignancies, thrombosis, and death compared with the TNF blocker regimen. In addition, rates of lung cancers and lymphomas were higher with tofacitinib. In trial data released earlier this year, Pfizer revealed that the tofacitinib group had a much higher incidence of adjudicated malignancies compared with the TNF blocker group (1.13 vs. 0.77 per 100 person-years; hazard ratio, 1.48; 95% confidence interval, 1.04-2.09).
Impact on clinical practice
Physicians treating patients who have rheumatoid arthritis with tofacitinib may initially decrease prescriptions following the FDA’s drug safety communication, said Daniel E. Furst, MD, professor of medicine (emeritus) at the University of California, Los Angeles, adjunct professor at the University of Washington, Seattle, and a research professor at the University of Florence (Italy) – particularly those with a principal mechanism of action slightly different from that of tofacitinib, he added.
“Tofacitinib is principally a JAK 1,3 inhibitor at usual concentrations, whereas upadacitinib and baricitinib are JAK 1,2 inhibitors. Thus, I speculate that the tofacitinib prescriptions will go down more than the upadacitinib and baricitinib prescriptions,” he said in an interview.
Some patients may also be worried about taking tofacitinib, particularly those with previous events or predisposing conditions, Dr. Furst noted.
“First and foremost, I think we need to actually look at the data in a publication rather than just an FDA statement before making huge changes in our practice,” he advised.
“I am looking forward to the data finally being published ... It’s interesting that the full data still isn’t really out there beyond the press releases and an abstract. I think there’s a lot more to learn about how these drugs work and who is really at risk for harmful events,” said Alexis R. Ogdie, MD, MSCE, associate professor of medicine and epidemiology at the University of Pennsylvania, Philadelphia.
Pfizer’s data also may be affecting FDA approvals of other JAK inhibitors. This past summer, AbbVie and Eli Lilly stated that the FDA’s ongoing assessment of the safety trial was delaying the agency’s decisions about expanding use of their respective drugs upadacitinib and baricitinib.
“I think many rheumatologists have already taken this information in, and begun to incorporate it into their discussions with their patients” since it has been over a year since the first public release of information about the ORAL Surveillance trial, said Arthur Kavanaugh, MD, professor of medicine at the University of California, San Diego. “I don’t know that it will affect the approvals, but it will impact their labels.”
Wariness to prescribing tofacitinib may be lower for patients younger than those in the ORAL Surveillance trial without additional cardiovascular risk factors who are taking tofacitinib for non-RA indications, said gastroenterologist Miguel Regueiro, MD.
“The JAK inhibitor warning by the FDA is an important consideration for any prescriber or patient. The risk of cardiovascular disease and venous thromboembolism with this class of medicine appears higher in older rheumatoid arthritis patients with underlying cardiovascular disease. While the warning applies to all JAK inhibitors and likely the newer selective JAK inhibitors to come, we need to weigh the risk and benefit based on the indication for prescribing,” said Dr. Regueiro, chair of the Digestive Disease and Surgery Institute and of the department of gastroenterology, hepatology and nutrition at the Cleveland Clinic in Ohio.
“I do think that there will be a heightened awareness and wariness for older RA patients and for the prescribers. However, for inflammatory bowel disease (and other non-RA indications), it does not appear that the risk for cardiovascular disease and VTE are significantly increased. To that end, in my own practice, I still use tofacitinib for ulcerative colitis and will do the same for the selective JAK inhibitors to come for IBD. Of course, as with any medication, we need to have discussions with our patients, alert them to potential side effects and have an open line of communication for any questions or concerns.”
Gastroenterologist Stephen Hanauer, MD, professor of medicine at Northwestern University, Chicago, thought that while patients with RA have many other treatment options besides JAK inhibitors, fewer options available to patients with IBD “may motivate the use of oral [sphingosine-1-phosphate receptor modulator] agents such as ozanimod, although IBD patients are younger and [have fewer] MACE risk factors than RA patients, so absolute risk is very small in the ulcerative colitis population.”
Pfizer’s data may be affecting FDA approvals of other JAK inhibitors. This past summer, AbbVie and Eli Lilly stated that the FDA’s ongoing assessment of the safety trial was delaying the agency’s decisions about expanding use of their respective drugs upadacitinib and baricitinib.
The agency’s decision corroborates an earlier 2019 warning about the increased risk of blood clots and of death in patients with ulcerative colitis taking 10 mg tofacitinib twice daily.
The FDA said that two other JAK inhibitors, ruxolitinib (Jakafi) and fedratinib (Inrebic), are not indicated for the treatment of arthritis and other inflammatory conditions, and so are not a part of the updates being required.
Baricitinib, abrocitinib, and upadacitinib are currently under FDA review for treating atopic dermatitis (AD); a topical formulation of the JAK1/2 inhibitor ruxolitinib is under review for treating AD. Reviews for all 4 have been extended. In September 2020, baricitinib was approved for treating moderate to severe AD in Europe, at a dose of 4 mg once a day, with recommendations that the dose can be reduced to 2 mg once a day when the disease is under control, and that the dose may need to be reduced in patients with impaired kidney function, those with an increased risk of infections, and those older than aged 75 years.
In an interview, Jacob Thyssen, MD, PhD, professor of dermatology at the University of Copenhagen, said that in the EU, there has been “extensive education” about cardiovascular risks with baricitinib “and it is my impression that payers and dermatologists in Europe are confident that it is safe to use in AD.” In addition, there has been an emphasis on the differences in cardiovascular risk factors between RA and AD patients, “given that the latter group is generally young and lean.” In the United States, he added, it will be interesting to see which doses of the JAK inhibitors will be approved for AD.
Dr. Thyssen disclosed that he is a speaker, advisory board member and/or investigator for Regeneron, Sanofi-Genzyme, Eli Lilly, Pfizer, LEO Pharma, AbbVie, and Almirall.

Children and COVID: Weekly cases top 200,000, vaccinations down
Weekly pediatric cases of COVID-19 exceeded 200,000 for just the second time during the pandemic, while new vaccinations in children continued to decline.
COVID-19 report. Total cases in children number almost 4.8 million since the pandemic started.
Vaccinations in children are following a different trend. Vaccine initiation has dropped 3 weeks in a row for both of the eligible age groups: First doses administered were down by 29% among 12- to 15-year-olds over that span and by 32% in 16- to 17-year-olds, according to data from the Centers for Disease Control and Prevention.
Since vaccination for children aged 12-15 years started in May, 49% had received at least one dose, and just over 36% were fully vaccinated as of Aug. 30. Among children aged 16-17 years, who have been eligible since December, 57.5% had gotten at least one dose of the vaccine and 46% have completed the two-dose regimen. The total number of children with at least one dose, including those under age 12 who are involved in clinical trials, was about 12 million, the CDC said on its COVID Data Tracker.
Hospitalizations are higher than ever
The recent rise in new child cases has been accompanied by an unprecedented increase in hospitalizations. The daily rate in children aged 0-17 years, which did not surpass 0.30 new admissions per 100,000 population during the worst of the winter surge, had risen to 0.45 per 100,000 by Aug. 26. Since July 4, when the new-admission rate was at its low point of 0.07 per 100,000, hospitalizations in children have jumped by 543%, based on data reported to the CDC by 5,251 hospitals.
A total of 52,245 children were admitted with confirmed COVID-19 from Aug. 1, 2020, when the CDC dataset begins, to Aug. 28, 2021. Those children represent 1.9% of all COVID admissions (2.7 million) in the United States over that period, the CDC said.
Total COVID-related deaths in children are up to 425 in the 48 jurisdictions (45 states, New York City, Puerto Rico, and Guam) that provide mortality data by age, the AAP and the CHA said.
Record-high numbers for the previous 2 reporting weeks – 23 deaths during Aug. 20-26 and 24 deaths during Aug. 13-19, when the previous weekly high was 16 – at least partially reflect the recent addition of South Carolina and New Mexico to the AAP/CHA database, as the two states just started reporting age-related data.

EDs saw more benzodiazepine overdoses, but fewer patients overall, in 2020
In a year when emergency department visits dropped by almost 18%, visits for benzodiazepine overdoses did the opposite, according to a report from the Centers for Disease Control and Prevention.
The actual increase in the number of overdose visits for benzodiazepine overdoses was quite small – from 15,547 in 2019 to 15,830 in 2020 (1.8%) – but the 11 million fewer ED visits magnified its effect, Stephen Liu, PhD, and associates said in the Morbidity and Mortality Weekly Report.
The rate of benzodiazepine overdose visits to all visits increased by 23.7% from 2019 (24.22 per 100,000 ED visits) to 2020 (29.97 per 100,000), with the larger share going to those involving opioids, which were up by 34.4%, compared with overdose visits not involving opioids (21.0%), the investigators said, based on data reported by 32 states and the District of Columbia to the CDC’s Drug Overdose Surveillance and Epidemiology system. All of the rate changes are statistically significant.
The number of overdose visits without opioid coinvolvement actually dropped, from 2019 (12,276) to 2020 (12,218), but not by enough to offset the decline in total visits, noted Dr. Liu, of the CDC’s National Center for Injury Prevention and Control and associates.
The number of deaths from benzodiazepine overdose, on the other hand, did not drop in 2020. Those data, coming from 23 states participating in the CDC’s State Unintentional Drug Overdose Reporting System, were available only for the first half of the year.
In those 6 months, The first quarter of 2020 also showed an increase, but exact numbers were not provided in the report. Overdose deaths rose by 22% for prescription forms of benzodiazepine and 520% for illicit forms in Q2 of 2020, compared with 2019, the researchers said.
Almost all of the benzodiazepine deaths (93%) in the first half of 2020 also involved opioids, mostly in the form of illicitly manufactured fentanyls (67% of all deaths). Between Q2 of 2019 and Q2 of 2020, involvement of illicit fentanyls in benzodiazepine overdose deaths increased from almost 57% to 71%, Dr. Liu and associates reported.
“Despite progress in reducing coprescribing [of opioids and benzodiazepines] before 2019, this study suggests a reversal in the decline in benzodiazepine deaths from 2017 to 2019, driven in part by increasing involvement of [illicitly manufactured fentanyls] in benzodiazepine deaths and influxes of illicit benzodiazepines,” they wrote.

CDC panel unanimously backs Pfizer vax, fortifying FDA approval
An independent expert panel within the Centers for Disease Control and Prevention (CDC) has studied the potential benefits and risks of the Pfizer-BioNTech COVID-19 vaccine and voted unanimously to recommend the shots for all Americans ages 16 and older.
fully approved by the U.S. Food and Drug Administration (FDA) last week.
The inoculation is still available to teens ages 12 to 15 under an emergency use authorization from the FDA.
ACIP now sends its recommendation to the CDC Director Rochelle Walensky, MD, for her sign off.
After reviewing the evidence behind the vaccine, panel member Sarah Long, MD, a professor of pediatrics at Drexel University College of Medicine, Philadelphia, said she couldn’t recall another instance where panelists had so much data on which to base their recommendation.
“This vaccine is worthy of the trust of the American people,” she said.
Doctors across the country use vaccines in line with the recommendations made by the ACIP. Their approval typically means that private and government insurers will cover the cost of the shots. In the case of the COVID-19 vaccines, the government is already picking up the tab.
Few surprises
The panel’s independent review of the vaccine’s effectiveness from nine studies held few surprises.
They found the Pfizer vaccine prevented a COVID infection with symptoms about 90%–92% of the time, at least for the first 4 months after the second shot. Protection against hospitalization and death was even higher.
The vaccine was about 89% effective at preventing a COVID infection without symptoms, according to a pooled estimate of five studies.
The data included in the review was updated only through March 13 of this year, however, and does not reflect the impact of further waning of immunity or the impact of the Delta variant.
In making their recommendation, the panel got an update on the safety of the vaccines, which have now been used in the United States for about 9 months.
The rate of anaphylaxis has settled at around five cases for every million shots given, according to the ACIP’s review of the evidence.
Cases of myocarditis and pericarditis were more common after getting a Pfizer-BioNTech vaccine than would be expected to happen naturally in the general population, but the risk was still very rare, and elevated primarily for men younger than age 30.
Out of 17 million second doses of Pfizer-BioNTech vaccines in the United States, there have been 327 confirmed cases of myocarditis reported to the Vaccine Adverse Event Reporting System in people who are younger than age 30. The average hospital stay for a myocarditis cases is 1 to 2 days.
So far, no one in the United States diagnosed with myocarditis after vaccination has died.
What’s more, the risk of myocarditis after vaccination was dwarfed by the risk of myocarditis after a COVID infection. The risk of myocarditis after a COVID infection was 6 to 34 times higher than the risk after receiving an mRNA vaccine.
About 11% of people who get the vaccine experience a serious reaction to the shot, compared with about 3% in the placebo group. Serious reactions were defined as pain; swelling or redness at the injection site that interferes with activity; needing to visit the hospital or ER for pain; tissue necrosis, or having skin slough off; high fever; vomiting that requires hydration; persistent diarrhea; severe headache; or muscle pain/severe joint pain.
“Safe and effective”
After hearing a presentation on the state of the pandemic in the US, some panel members were struck and shaken that 38% of Americans who are eligible are still not fully vaccinated.
Pablo Sanchez, MD, a pediatrician at Nationwide Children’s Hospital in Columbus, Ohio, said, “We’re doing an abysmal job vaccinating the American people. The message has to go out that the vaccines are safe and effective.”

FDA fully approves Pfizer COVID-19 vaccine
The Food and Drug Administration has granted a biological license application, more commonly known as “full approval,” to the Pfizer-BioNTech COVID-19 vaccine.
It is the first COVID-19 vaccine to be fully licensed in the United States. It will be marketed under the trade name Comirnaty.
The approval applies to individuals ages 16 years and older. The vaccine is still available for emergency use for those ages 12-15.
The FDA’s stamp of approval is somewhat anticlimactic, following months of real-world use and millions of doses doled out to the general population. It comes after months of scrutiny by the agency of the clinical trial data.
Still, the approval puts the vaccines on firmer legal footing and is expected to spur a raft of new vaccination requirements by employers, schools, and universities.
“The FDA approval is the gold standard,” President Joe Biden said from the White House. “Those who have been waiting for full approval should go and get your shot now.”
“It could save your life or the lives of those you love,” he said.
Biden also called on businesses to mandate COVID vaccines for their employees.
Indeed, soon after the approval was announced, Defense Secretary Lloyd Austin said the vaccines would be required for all 1.4 million active duty service members.
Public health advocates have seen full approval as an important tool to increase U.S. vaccination rates and had criticized the FDA for taking so long to grant the license.
In a news briefing on the approval, Peter Marks, MD, director of the FDA’s Center for Biologics Evaluation and Research, said the agency had not dragged its feet.
Marks noted that his team had reviewed tens of thousands of pages of clinical trial data -- down to the level of individual patients. They also inspected clinical trial sites and manufacturing facilities, and reviewed information gathered after the vaccines were authorized for use.
“It’s been 97 days since Pfizer completed the role of its [application for approval] and the clock started, which means that we completed this in about 40% of the normal clock time for a submission of this magnitude,” he said. “People worked day and night.”
The agency resisted pressure to speed up its process, saying a thorough review was necessary to ensure public confidence.
“While millions of people have already safely received COVID-19 vaccines, we recognize that for some, the FDA approval of a vaccine may now instill additional confidence to get vaccinated. Today’s milestone puts us one step closer to altering the course of this pandemic in the U.S.,” acting FDA Commissioner Janet Woodcock said in a FDA news release.
Experts agreed the move would increase public confidence.
“I don't expect a big line outside of vaccination sites this afternoon or tomorrow morning, but it will persuade some,” said William Schaffner, MD, a professor of infectious diseases at Vanderbilt University in Nashville.
A recent Kaiser Family Foundation poll found that 3 in 10 unvaccinated adults said they would be more likely to get vaccinated if the vaccines were given full approval.
More importantly, Schaffner said, the FDA’s approval would lay the groundwork for vaccine mandates. “I think those kinds of mandates are going to be necessary to get us up over 80% vaccinated.”
In granting the approval, the agency reviewed a record amount of data from more than 40,000 people who took part in clinical trials. About 12,000 recipients have been followed for at least 6 months, the agency said.
The FDA also reviewed safety data collected since it issued its emergency use authorization for the shots in December.
Based on the results from the clinical trials, the vaccine was 91% effective at preventing COVID-19 disease. But that estimate came from data collected before the Delta variant became widespread.
The most commonly reported side effects in the clinical trials were pain, redness and swelling at the injection site, fatigue, headache, muscle or joint pain, chills, and fever.
The FDA said the vaccine is effective in preventing COVID-19 and potentially serious outcomes, including hospitalization and death.
Based on safety data reviewed since the two-dose vaccine was approved, the FDA said the data demonstrates a higher risk for heart inflammation -- clinically known as myocarditis or pericarditis -- especially within 7 days after the second dose of the shots. The risk is highest for men under age 40, compared to women and older men.
The prescription information includes warnings about these risks. The FDA said the drugmakers must continue to study the risks and long-term effects on people who have myocarditis after vaccination.

CDC launches new center to watch for future outbreaks
The Centers for Disease Control and Prevention is setting up a new hub to watch for early warning signs of future infectious outbreaks, the agency announced on Aug. 18.
Epidemiologists learn about emerging outbreaks by tracking information, and the quality of their analysis depends on their access to high-quality data. Gaps in existing systems became obvious during the COVID-19 pandemic as experts were challenged by the crisis.
The new Center for Forecasting and Outbreak Analytics will, in part, work like a meteorological office that tracks weather-related changes, only the center will track possible flareups in infectious disease.
The day after he took office, President Joe Biden pledged to modernize the country’s system for public health data. First funding for the initiative will come from the American Rescue Plan.
“We are excited to have the expertise and ability to model and forecast public health concerns and share information in real-time to activate governmental, private sector, and public actions in anticipation of threats both domestically and abroad,” CDC Director Rochelle Walensky, MD, said in a statement.
Devastating toll of COVID-19
Many world leaders are now responding to the destruction of the health crisis and are investing in new infrastructure. A July report from a G-20 panel calls for $75 billion in international financing for pandemic prevention and preparedness –twice as much as current spending levels.
Testifying in a congressional hearing, epidemiologist Caitlin Rivers, PhD, from the Johns Hopkins Center for Health Security, Baltimore, voiced the importance of never being caught unprepared again.
“We were unprepared to manage the emergence and swift global spread of the novel coronavirus, and we were late to recognize when it reached our shores. Those delays set us on a worse trajectory than we might have otherwise faced,” she said.
Dr. Rivers will join the new center’s leadership team as associate director working alongside Marc Lipsitch, PhD, director for science.
“The new center will meet a longstanding need for a national focal point to analyze data and forecast the trajectory of pandemics with the express goal of informing and improving decisions with the best available evidence,” Dr. Lipsitch said in the CDC’s news release announcing the new center.
Experts will map what data sources are needed to assist disease modelers and public health emergency responders tracking emerging problems that they can share with decision-makers. They will expand tracking capability and data sharing using open-source software and application programming with existing and new data streams from the public health ecosystem and elsewhere.
Dylan George, PhD, who will be the center’s director for operations, said in the CDC news release that the center will provide critical information to communities so they can respond.
“Pandemics threaten our families and communities at speed and scale – our response needs to move at speed and scale, too,” he said.

The Centers for Disease Control and Prevention is setting up a new hub to watch for early warning signs of future infectious outbreaks, the agency announced on Aug. 18.
Epidemiologists learn about emerging outbreaks by tracking information, and the quality of their analysis depends on their access to high-quality data. Gaps in existing systems became obvious during the COVID-19 pandemic as experts were challenged by the crisis.
The new Center for Forecasting and Outbreak Analytics will, in part, work like a meteorological office that tracks weather-related changes, only the center will track possible flareups in infectious disease.
The day after he took office, President Joe Biden pledged to modernize the country’s system for public health data. First funding for the initiative will come from the American Rescue Plan.
“We are excited to have the expertise and ability to model and forecast public health concerns and share information in real-time to activate governmental, private sector, and public actions in anticipation of threats both domestically and abroad,” CDC Director Rochelle Walensky, MD, said in a statement.
Devastating toll of COVID-19
Many world leaders are now responding to the destruction of the health crisis and are investing in new infrastructure. A July report from a G-20 panel calls for $75 billion in international financing for pandemic prevention and preparedness –twice as much as current spending levels.
Testifying in a congressional hearing, epidemiologist Caitlin Rivers, PhD, from the Johns Hopkins Center for Health Security, Baltimore, voiced the importance of never being caught unprepared again.
“We were unprepared to manage the emergence and swift global spread of the novel coronavirus, and we were late to recognize when it reached our shores. Those delays set us on a worse trajectory than we might have otherwise faced,” she said.

Children and COVID: New cases rise to winter levels
Weekly cases of COVID-19 in children topped 100,000 for the first time since early February, according to the American Academy of Pediatrics and the Children’s Hospital Association.
weekly COVD-19 report. The recent surge in child COVID has also brought a record high in hospitalizations and shortages of pediatric ICU beds in some areas.
The 121,000 new cases represent an increase of almost 1,400% since June 18-24, when the weekly tally was just 8,447 and at its lowest point in over a year, the AAP/CHA data show.
On the vaccination front in the last week (Aug. 10-16), vaccine initiation for 12- to 17-year-olds was fairly robust but still down slightly, compared with the previous week. Just over 402,000 children aged 12-15 years received a first vaccination, which was down slightly from 411,000 the week before but still higher than any of the 6 weeks from June 22 to Aug. 2, based on data from the Centers for Disease Control and Prevention. Vaccinations were down by a similar margin for 15- to-17-year-olds.
Over 10.9 million children aged 12-17 have had at least one dose of COVID-19 vaccine administered, of whom 8.1 million are fully vaccinated. Among those aged 12-15 years, 44.5% have gotten at least one dose and 31.8% are fully vaccinated, with corresponding figures of 53.9% and 42.5% for 16- and 17-year-olds, according to the CDC’s COVID Data Tracker.
The number of COVID-19 cases reported in children since the start of the pandemic is up to 4.4 million, which makes up 14.4% of all cases in the United States, the AAP and CHA said. Other cumulative figures through Aug. 12 include almost 18,000 hospitalizations – reported by 23 states and New York City – and 378 deaths – reported by 43 states, New York City, Puerto Rico, and Guam.
In the latest edition of their ongoing report, compiled using state data since the summer of 2020, the two groups noted that, “in the summer of 2021, some states have revised cases counts previously reported, begun reporting less frequently, or dropped metrics previously reported.” Among those states are Nebraska, which shut down its online COVID dashboard in late June, and Alabama, which stopped reporting cumulative cases and deaths after July 29.

CDC officially endorses third dose of mRNA vaccines for immunocompromised
Centers for Disease Control and Prevention Director Rochelle Walensky, MD, has officially signed off on a recommendation by an independent panel of 11 experts to allow people with weakened immune function to get a third dose of certain COVID-19 vaccines.
The decision follows a unanimous vote by the CDC’s Advisory Committee on Immunization Practices (ACIP), which in turn came hours after the U.S. Food and Drug Administration updated its Emergency Use Authorization (EUA) for the Pfizer and Moderna mRNA vaccines.
About 7 million adults in the United States have moderately to severely impaired immune function because of a medical condition they live with or a medication they take to manage a health condition.
People who fall into this category are at higher risk of being hospitalized or dying if they get COVID-19. They are also more likely to transmit the infection. About 40% of vaccinated patients who are hospitalized with breakthrough cases are immunocompromised.
Recent studies have shown that between one-third and one-half of immunocompromised people who didn’t develop antibodies after two doses of a vaccine do get some level of protection after a third dose.
Even then, however, the protection immunocompromised people get from vaccines is not as robust as someone who has healthy immune function, and some panel members were concerned that a third dose might come with a false sense of security.
“My only concern with adding a third dose for the immunocompromised is the impression that our immunocompromised population [will] then be safe,” said ACIP member Helen Talbot, MD, MPH, an associate professor of medicine at Vanderbilt University Medical Center in Nashville, Tenn.
“I think the reality is they’ll be safer but still at incredibly high risk for severe disease and death,” she said.
In updating its EUA, the FDA stressed that, even after a third dose, people who are immunocompromised will still need to wear a mask indoors, socially distance, and avoid large crowds. In addition, family members and other close contacts should be fully vaccinated to protect these vulnerable individuals.
Johnson & Johnson not in the mix
The boosters will be available to children as young as 12 years of age who’ve had a Pfizer vaccine or those ages 18 and older who’ve gotten the Moderna vaccine.
For now, people who’ve had the one-dose Johnson & Johnson vaccine have not been cleared to get a second dose of any vaccine.
FDA experts acknowledged the gap but said that people who had received the Johnson & Johnson vaccine represented a small slice of vaccinated Americans, and said they couldn’t act before the FDA had updated its authorization for that vaccine, which the agency is actively exploring.
“We had to do what we’re doing based on the data we have in hand,” said Peter Marks, MD, director of the Center for Biologics Evaluation and Research at the FDA, the division of the agency that regulates vaccines.
“We think at least there is a solution here for the very large majority of immunocompromised individuals, and we believe we will probably have a solution for the remainder in the not-too-distant future,” Dr. Marks said.
In its updated EUA, the FDA said that the third shots were intended for people who had undergone solid organ transplants or have an “equivalent level of immunocompromise.”
The details
Clinical experts on the CDC panel spent a good deal of time trying to suss out exactly what conditions might fall under the FDA’s umbrella for a third dose.
In a presentation to the committee, Neela Goswami, MD, PhD, an assistant professor of infectious diseases at Emory University School of Medicine and of epidemiology at the Emory Rollins School of Public Health, Atlanta, stressed that the shots are intended for patients who are moderately or severely immunocompromised, in close consultation with their doctors, but that people who should qualify would include those:
- Receiving treatment for solid tumors or blood cancers
- Taking immunosuppressing medications after a solid organ transplant
- Within 2 years of receiving CAR-T therapy or a stem cell transplant
- Who have primary immunodeficiencies – rare genetic disorders that prevent the immune system from working properly
- With advanced or untreated
- Taking high-dose corticosteroids (more than 20 milligrams of or its equivalent daily), alkylating agents, antimetabolites, chemotherapy, TNF blockers, or other immunomodulating or immunosuppressing biologics
- With certain chronic medical conditions, such as or asplenia – living without a spleen
- Receiving dialysis
In discussion, CDC experts clarified that these third doses were not intended for people whose immune function had waned with age, such as elderly residents of long-term care facilities or people with chronic diseases like diabetes.
The idea is to try to get a third dose of the vaccine they’ve already had – Moderna or Pfizer – but if that’s not feasible, it’s fine for the third dose to be different from what someone has had before. The third dose should be given at least 28 days after a second dose, and, ideally, before the initiation of immunosuppressive therapy.
Participants in the meeting said that the CDC would post updated materials on its website to help guide physicians on exactly who should receive third doses.
Ultimately, however, the extra doses will be given on an honor system; no prescriptions or other kinds of clinical documentation will be required for people to get a third dose of these shots.
Tests to measure neutralizing antibodies are also not recommended before the shots are given because of differences in the types of tests used to measure these antibodies and the difficulty in interpreting them. It’s unclear right now what level of neutralizing antibodies is needed for protection.
‘Peace of mind’
In public testimony, Heather Braaten, a 44-year-old being treated for ovarian cancer, said she was grateful to have gotten two shots of the Pfizer vaccine last winter, in between rounds of chemotherapy, but she knew she was probably not well protected. She said she’d become obsessive over the past few months reading medical studies and trying to understand her risk.
“I have felt distraught over the situation. My prognosis is poor. I most likely have about two to three years left to live, so everything counts,” Ms. Braaten said.
She said her life ambitions were humble. She wants to visit with friends and family and not have to worry that she’ll be a breakthrough case. She wants to go grocery shopping again and “not panic and leave the store after five minutes.” She’d love to feel free to travel, she said.
“While I understand I still need to be cautious, I am hopeful for the peace of mind and greater freedom a third shot can provide,” Ms. Braaten said.
More boosters on the way?
In the second half of the meeting, the CDC also signaled that it was considering the use of boosters for people whose immunity might have waned in the months since they had completed their vaccine series, particularly seniors. About 75% of people hospitalized with vaccine breakthrough cases are over age 65, according to CDC data.
Those considerations are becoming more urgent as the Delta variant continues to pummel less vaccinated states and counties.
In its presentation to the ACIP, Heather Scobie, PhD, MPH, a member of the CDC’s COVID Response Team, highlighted data from Canada, Israel, Qatar, and the United Kingdom showing that, while the Pfizer vaccine was still highly effective at preventing hospitalizations and death, it’s far less likely when faced with Delta to prevent an infection that causes symptoms.
In Israel, Pfizer’s vaccine prevented symptoms an average of 41% of the time. In Qatar, which is also using the Moderna vaccine, Pfizer’s prevented symptomatic infections with Delta about 54% of the time compared with 85% with Moderna’s.
Dr. Scobie noted that Pfizer’s waning efficacy may have something to do with the fact that it uses a lower dosage than Moderna’s. Pfizer’s recommended dosing interval is also shorter – 3 weeks compared with 4 weeks for Moderna’s. Stretching the time between shots has been shown to boost vaccine effectiveness, she said.
New data from the Mayo clinic, published ahead of peer review, also suggest that Pfizer’s protection may be fading more quickly than Moderna’s.
In February, both shots were nearly 100% effective at preventing the SARS-CoV-2 infection, but by July, against Delta, Pfizer’s efficacy had dropped to somewhere between 13% and 62%, while Moderna’s was still effective at preventing infection between 58% and 87% of the time.
In July, Pfizer’s was between 24% and 94% effective at preventing hospitalization with a COVID-19 infection and Moderna’s was between 33% and 96% effective at preventing hospitalization.
While that may sound like cause for concern, Dr. Scobie noted that, as of August 2, severe COVD-19 outcomes after vaccination are still very rare. Among 164 million fully vaccinated people in the United States there have been about 7,000 hospitalizations and 1,500 deaths; nearly three out of four of these have been in people over the age of 65.
The ACIP will next meet on August 24 to focus solely on the COVID-19 vaccines.

- Within 2 years of receiving CAR-T therapy or a stem cell transplant
- Who have primary immunodeficiencies – rare genetic disorders that prevent the immune system from working properly
- With advanced or untreated
- Taking high-dose corticosteroids (more than 20 milligrams of or its equivalent daily), alkylating agents, antimetabolites, chemotherapy, TNF blockers, or other immunomodulating or immunosuppressing biologics
- With certain chronic medical conditions, such as or asplenia – living without a spleen
- Receiving dialysis
In discussion, CDC experts clarified that these third doses were not intended for people whose immune function had waned with age, such as elderly residents of long-term care facilities or people with chronic diseases like diabetes.
The idea is to try to get a third dose of the vaccine they’ve already had – Moderna or Pfizer – but if that’s not feasible, it’s fine for the third dose to be different from what someone has had before. The third dose should be given at least 28 days after a second dose, and, ideally, before the initiation of immunosuppressive therapy.
Participants in the meeting said that the CDC would post updated materials on its website to help guide physicians on exactly who should receive third doses.
Ultimately, however, the extra doses will be given on an honor system; no prescriptions or other kinds of clinical documentation will be required for people to get a third dose of these shots.
Tests to measure neutralizing antibodies are also not recommended before the shots are given because of differences in the types of tests used to measure these antibodies and the difficulty in interpreting them. It’s unclear right now what level of neutralizing antibodies is needed for protection.
‘Peace of mind’
In public testimony, Heather Braaten, a 44-year-old being treated for ovarian cancer, said she was grateful to have gotten two shots of the Pfizer vaccine last winter, in between rounds of chemotherapy, but she knew she was probably not well protected. She said she’d become obsessive over the past few months reading medical studies and trying to understand her risk.
“I have felt distraught over the situation. My prognosis is poor. I most likely have about two to three years left to live, so everything counts,” Ms. Braaten said.
She said her life ambitions were humble. She wants to visit with friends and family and not have to worry that she’ll be a breakthrough case. She wants to go grocery shopping again and “not panic and leave the store after five minutes.” She’d love to feel free to travel, she said.
“While I understand I still need to be cautious, I am hopeful for the peace of mind and greater freedom a third shot can provide,” Ms. Braaten said.
More boosters on the way?
In the second half of the meeting, the CDC also signaled that it was considering the use of boosters for people whose immunity might have waned in the months since they had completed their vaccine series, particularly seniors. About 75% of people hospitalized with vaccine breakthrough cases are over age 65, according to CDC data.
Those considerations are becoming more urgent as the Delta variant continues to pummel less vaccinated states and counties.
In its presentation to the ACIP, Heather Scobie, PhD, MPH, a member of the CDC’s COVID Response Team, highlighted data from Canada, Israel, Qatar, and the United Kingdom showing that, while the Pfizer vaccine was still highly effective at preventing hospitalizations and death, it’s far less likely when faced with Delta to prevent an infection that causes symptoms.
In Israel, Pfizer’s vaccine prevented symptoms an average of 41% of the time. In Qatar, which is also using the Moderna vaccine, Pfizer’s prevented symptomatic infections with Delta about 54% of the time compared with 85% with Moderna’s.
Dr. Scobie noted that Pfizer’s waning efficacy may have something to do with the fact that it uses a lower dosage than Moderna’s. Pfizer’s recommended dosing interval is also shorter – 3 weeks compared with 4 weeks for Moderna’s. Stretching the time between shots has been shown to boost vaccine effectiveness, she said.
New data from the Mayo clinic, published ahead of peer review, also suggest that Pfizer’s protection may be fading more quickly than Moderna’s.
In February, both shots were nearly 100% effective at preventing the SARS-CoV-2 infection, but by July, against Delta, Pfizer’s efficacy had dropped to somewhere between 13% and 62%, while Moderna’s was still effective at preventing infection between 58% and 87% of the time.
In July, Pfizer’s was between 24% and 94% effective at preventing hospitalization with a COVID-19 infection and Moderna’s was between 33% and 96% effective at preventing hospitalization.
While that may sound like cause for concern, Dr. Scobie noted that, as of August 2, severe COVD-19 outcomes after vaccination are still very rare. Among 164 million fully vaccinated people in the United States there have been about 7,000 hospitalizations and 1,500 deaths; nearly three out of four of these have been in people over the age of 65.
The ACIP will next meet on August 24 to focus solely on the COVID-19 vaccines.

CDC reports Burkholderia cepacia and B. pseudomallei outbreaks
The Centers for Disease Control and Prevention and Food and Drug Administration have announced an outbreak of at least 15 Burkholderia cepacia infections associated with contaminated ultrasound gel used to guide invasive procedures as well as an unrelated outbreak of Burkholderia pseudomallei that caused two deaths.
The procedures involved in the B. cepacia outbreak included placement of both central and peripheral intravenous catheters and paracentesis (removal of peritoneal fluid from the abdominal cavity). Cases have occurred in several states.
Further testing has shown the presence of Burkholderia stabilis, a member of B. cepacia complex (Bcc), in four lots of unopened bottles of MediChoice M500812 ultrasound gel. Eco-Med Pharmaceuticals of Etobicoke, Ont., the parent manufacturer, has issued a recall of MediChoice M500812 or Eco-Gel 200 with the following lot numbers: B029, B030, B031, B032, B040, B041, B048, B055. A similar outbreak occurred in Canada.
Some of these cases resulted in bloodstream infections. Further details are not yet available. Bcc infections have ranged from asymptomatic to life-threatening pneumonias, particularly in patients with cystic fibrosis. Other risk factors include immunosuppression, mechanical ventilation, and the use of other invasive venous or urinary catheters.
Kiran M. Perkins, MD, MPH, outbreak lead with the CDC’s Prevention Research Branch, said in an interview via email that automated systems such as Vitek might have trouble identifying the organism as “the system may only reveal the microbial species at the genus level but not at the species level, and/or it may have difficulty distinguishing between members of closely related group members.”
In the CDC’s experience, “most facilities do not conduct further species identification.” The agency added that it cannot tell if there has been any increase in cases associated with COVID-19, as they are not notifiable diseases and the “CDC does not systematically collect information on B. cepacia complex infections.”
Rodney Rohde, PhD, professor of clinical laboratory science and chair of the clinical laboratory science program, Texas State University, San Marcos, told this news organization via email that Burkholderia’s “detection in the manufacturing process is difficult, and product recalls are frequent.” He added, “A recent review by the Food and Drug Administration in the U.S. found that almost 40% of contamination reports in both sterile and nonsterile pharmaceutical products were caused by Bcc bacteria.” Another problem is that they often create biofilms, so “they are tenacious environmental colonizers of medical equipment and surfaces in general.”
There have been many other outbreaks as a result to B. cepacia complex. Because it is often in the water supply used in pharmaceutical manufacturing and is resistant to preservatives, the FDA cautions that it poses a risk of contamination in all nonsterile, water-based drug products.
Recalls have included contaminated antiseptics, such as povidone iodine, benzalkonium chloride, and chlorhexidine gluconate. Contamination in manufacturing may not be uniform, and only some samples may be affected. Antiseptic mouthwashes have also been affected. So have nonbacterial soaps and docusate (a stool softener) solutions, and various personal care products, including nasal sprays, lotions, simethicone gas relief drops (Mylicon), and baby wipes.
Although Bcc are considered “objectionable organisms,” there have been no strong or consistent standards for their detection from the U.S. Pharmacopeia, and some manufacturers reportedly underestimate the consequences of contamination. The FDA issued a guidance to manufacturers in 2017 on quality assurance and cleaning procedures. This is particularly important since preservatives are ineffective against Bcc, and sterility has to be insured at each step of production.
Burkholderia isolates are generally resistant to commonly used antibiotics. Treatment might therefore include a combination of two drugs (to try to limit the emergence of more resistance) such as ceftazidime, piperacillin, meropenem with trimethoprim-sulfamethoxazole, or a beta-lactam plus aminoglycoside.
Interestingly, an outbreak of Burkholderia pseudomallei was just reported by the CDC as well. This is a related gram-negative bacillus which is quite uncommon in the United States. It causes melioidosis, usually a tropical infection, which presents with nonspecific symptoms or serious pneumonia, abscesses, or bloodstream infections.
Four cases have been identified this year in Georgia, Kansas, Minnesota, and Texas, two of them fatal. It is usually acquired from soil or water. By genomic analysis, the four cases are felt to be related, but no common source of exposure has been identified. They also appear to be closely related to South Asian strains, although none of the patients had traveled internationally. Prolonged antibiotic therapy with ceftazidime or meropenem, followed by 3-6 months of trimethoprim-sulfamethoxazole, is often required.
In his email, Dr. Rohde stated, “Melioidosis causes cough, chest pain, high fever, headache or unexplained weight loss, but it may take 2-3 weeks for symptoms of melioidosis to appear after a person’s initial exposure to the bacteria. So, one could see how this might be overlooked as COVID per symptoms and per the limitations of laboratory identification.”
It’s essential for clinicians to recognize that automated microbiology identification systems can misidentify B. pseudomallei as B. cepacia and to ask the lab for more specialized molecular diagnostics, particularly when relatively unusual organisms are isolated.
Candice Hoffmann, a public affairs specialist at the CDC, told this news organization that “clinicians should consider melioidosis as a differential diagnosis in both adult and pediatric patients who are suspected to have a bacterial infection (pneumonia, sepsis, meningitis, wound) and are not responding to antibacterial treatment, even if they have not traveled outside of the continental United States.”
Dr. Rohde has disclosed no relevant financial relationships.

Surge of new child COVID cases continues for 6th consecutive week
The current COVID-19 surge has brought new cases in children to their highest level since February, according to a new report.
New pediatric cases rose for the 6th straight week, with almost 94,000 reported for the week ending Aug. 5.
That weekly total was up by 31% over the previous week and by over 1,000% since late June, when the new-case figure was at its lowest point (8,447) since early in the pandemic, the American Academy of Pediatrics and the Children’s Hospital Association said. COVID-related deaths – 13 for the week – were also higher than at any time since March 2021.
Almost 4.3 million children have been infected with SARS-CoV-2, which is 14.3% of all cases reported in 49 states (excluding New York), the District of Columbia, New York City, Puerto Rico, and Guam. Children represented 15.0% of the new cases reported in those jurisdictions during the week ending Aug. 5, the AAP and CHA said in their weekly report.
Another measure that has been trending upward recently is vaccine initiation among 12- to 15-year-olds, although the latest weekly total is still well below the high of 1.4 million seen in May. First-time vaccinations reached almost 411,000 for the week of Aug. 3-9, marking the fourth consecutive increase in that age group, the Centers for Disease Control and Prevention said on its COVID Data Tracker. Vaccinations also increased, although more modestly, for 16- and 17-year-olds in the most recent week.
Cumulative figures for children aged 12-17 show that almost 10.4 million have received at least one dose and that 7.7 million are fully vaccinated as of Aug. 9. By age group, 42.2% of those aged 12-15 have received at least one dose, and 30.4% have completed the vaccine regimen. Among those aged 16-17 years, 52.2% have gotten their first dose, and 41.4% are fully vaccinated, according to the COVID Data Tracker.
Looking at vaccination rates on the state level shows that only 20% of children aged 12-17 in Wyoming and 21% in Mississippi have gotten at least one dose as of Aug. 4, while Massachusetts is up to 68% and Vermont reports 70%. Rates for full vaccination range from 11% in Mississippi and Alabama to 61% in Vermont, based on an AAP analysis of CDC data, which is not available for Idaho.
