Are Vaccine Boosters Widely Needed? Some Federal Advisers Have Misgivings.


A series of endorsements from scientific panels advising federal agencies over the past month has resulted in tens to millions of Americans being eligible for coronavirus vaccination booster shots.

But the recommendations — even those approved unanimously — mask significant dissent and disquiet among those advisers about the need for booster shots in the United States.

Interviews last week with several experts from the Centers for Disease Control and Prevention and the Food and Drug Administration revealed that data shows that the vast majority of Americans, except for those over 65, are well protected against serious illness and don’t need booster shots.

All the advisers acknowledged that they were obligated to make difficult choices, based on sparse research, in the middle of a public health emergency. Some advisers claimed that they felt pressured to vote for the shots due to the way federal agencies frame the questions.

Other experts on the committee stated that they were trying to avoid confusion by not dissipating, or that their votes were based on their view of the evidence. They were just overruled.

“These recommendations are not evidence-based,” stated Dr. Sarah S. Long of Drexel University in Philadelphia and a member of C.D.C. Advisory Committee on Immunization Practices.

After a series vote, the official position was determined by the F.D.A. and C.D.C. It is now possible to receive a booster dose of any one of these vaccines for older adults, certain medical conditions, as well as those whose lives are regularly exposed to the virus.

C.D.C. Last week, C.D.C. advised people in certain high-risk populations that they could choose another type of Covid-19 booster.

“I don’t think we have evidence that all those in these groups need a booster now,” said Dr. Matthew Daley from Kaiser Permanente Colorado. Daley is a senior investigator and member of the C.D.C. advisory committee.

Dr. Long and Dr. Daley both voted in favor of booster shots at their committee’s meeting on Thursday, but with reservations over how the decision would be viewed by anxious Americans who might conclude mistakenly that the vaccines are ineffective.

When the C.D.C. When the C.D.C. Two of the 15 panelists voted against booster doses for adults over age 50 with certain medical conditions.

In a vote of 9 to 6, boosters approved for those aged 18 to 49 who have other medical risk factors was approved. The booster recommendation for those whose jobs put them at risk was not approved.

This category was not included in the final C.D.C. recommendations only because Dr. Rochelle Walensky, the agency’s director, overruled her advisers.

“You can feel the hesitancy” in all this, said Dr. Paul Offit. Offit is the director at the Vaccine Education Center at Children’s Hospital Philadelphia. He also serves as a member F.D.A.’s vaccin advisory committee. “It’s because in our hearts, I think people don’t quite agree with this notion of a booster dose.”

Dr. Offit continued, “The doors just kept getting bigger and bigger and greater and it got wider and farther with each step.” “The companies got the things they wanted, the administration got the things they wanted.”

Interviews with experts revealed that there was limited evidence on the safety of booster shots. Dr. Kathleen Dooling (C.D.C.) said that the data supporting booster shots of Moderna or Johnson & Johnson vaccines is “of very low quality.” On Thursday, the scientist was acknowledged by the committee.

Some felt they still had to vote to approve booster shots of Moderna & Johnson’s vaccines. They had already recommended boosters in the Pfizer BioNTech vaccine, and they didn’t want to deny the rest of America.

“The problem that trounced me was that we don’t know if boosters were necessary,” stated Dr. Cody Meissner of Tufts University School of Medicine, and member of F.D.A. advisory committee.

He added that “if it’s going to be done for one group I think fairness kinda dictates you have the same thing for all the other groups.”

Interviews with panelists were difficult because they did not want their opinions to influence the final decisions by the committees.

“It’s difficult for us to show some of our doubts, because it’s not right to have mixed messages,” stated Dr. Camille Kotton. Camille Kotton is an infectious diseases physician at Massachusetts General Hospital. committee.

However, several panelists did not want to speak on record and said privately that they knew the final recommendations for booster shot were coming as soon as President Biden promised them all adults.

Dr. Long said that she is in an extremely difficult place to do anything but what everyone has already stated.

She said that some administration officials “pay lip service” to science and evidence.

Experts outside these committees also said that President Biden’s promise of boosters, in August, made it difficult for the agencies to weigh the data objectively in September and October.

“The perception is that the horse is out of the barn, and there’s not really much you can do at this point,” said Dr. Celine Gounder, an infectious disease specialist at Bellevue Hospital Center who has previously advised the Biden administration.

“The truth is, you cannot have this confusing mess — It’s going to cause more problems,” she said, referring specifically to mixed signals from federal scientists and the White House.

Much of the dissent in recent hearings sprang from one central contention: that the coronavirus vaccines, like nearly all other vaccines, should be used to prevent illness severe enough to require medical attention, not milder infection.

The bulk of the evidence presented to the federal advisers demonstrated only that the original immunizations were waning in potency against infections. Except for older Americans, the vaccines appear to be stable against severe Covid-19 death and other serious diseases.

How to Use Covid-19 Booster shots

F.D.A. The F.D.A. has approved booster shots for millions who have received the Pfizer-BioNTech or Moderna vaccines. Moderna and Pfizer recipients eligible for a booster are people aged 65 or older and those at higher risk due to medical conditions or their work. A booster can be obtained by eligible Moderna and Pfizer recipients within six months of their second dose. All Johnson & Johnson beneficiaries will be eligible for a supplementary shot two months after the last.

Yes. Yes. The F.D.A. Although regulators do not recommend any vaccine over another for boosters, they have not done so. They also remain silent about whether it is better to use the same vaccine whenever possible.

The C.D.C. The C.D.C. has stated that certain conditions qualify for a booster injection. These include hypertension, heart disease, diabetes or obesity, cancer or blood disorders and weakened immune systems. Eligible are women who are pregnant, as well as former and current smokers.

F.D.A. The F.D.A. authorized boosters for workers whose job puts them at high risk of being exposed to potentially infectious people. C.D.C. says that group includes: emergency medical workers; education workers; food and agriculture workers; manufacturing workers; corrections workers; U.S. Postal Service workers, public transit workers, grocery store workers.

Yes. Yes. According to the C.D.C.

Dr. Kotton stated that “I don’t believe we ever get 100 percent protection from any vaccination.” “The goal to get to zero is a lofty one, and unfortunately not achievable.”

“People are using it to be anxious about Covid and about the global state of affairs,” she stated, referring also to booster shots.

Generally, scientists on the two committees are asked to vote yes or no on questions posed to them by the federal agencies they are advising. In some cases, committee members claimed that they voted one or the other because of the question’s formulation.

F.D.A. began to investigate the December Pfizer/BioNTech vaccine. Advisors assessed the Pfizer BioNTech vaccine for people aged 16 and over. They found that there was not enough evidence to support its use in 16- or 17-year olds.

Dr. Archana Chaterjee and three of her fellow members of the committee voted against the vaccine, and were harshly criticized for their vote. Dr. Chatterjee claimed that she would have voted different if the F.D.A. had asked her. I had asked Dr. Chatterjee about the approval of the vaccine for adults over 18 years.

“We were basically told, ‘Here’s the question, and say yes or no,'” said Dr. Chatterjee, a pediatric infectious disease expert and dean of the Chicago Medical School. “We were also not allowed to explain the vote.”

In subsequent meetings, the F.D.A. The F.D.A. allowed science advisors to ask for changes to the question or to explain their votes. However, they can only vote on data contained in company applications.

At a recent meeting, F.D.A. representatives discussed this issue. According to advisers, they wanted to suggest that Johnson & Johnson recipients should have the choice of any vaccine for their booster. The F.D.A. The F.D.A. merely requested that the panel vote on a Johnson & Johnson booster.

Dr. Stanley Perlman of the panel said he voted in favor because Johnson & Johnson recipients would see a benefit from a second shot. Dr. Stanley Perlman of the University of Iowa said that the unanimous vote showed more faith in Johnson & Johnson vaccination as a booster than he thought. He is an immunologist who also specializes in coronavirus.

Dr. Perlman stated that he initially opposed boosters for young people, but voted for them for other reasons. He stated that he didn’t want any doctors or nurses staying at home with asymptomatic infections in the case of health workers.

Experts said that they had tried to be transparent about the limitations and rationale behind their choices. However, communicating during a pandemic proved difficult.

Dr. Kotton stated that the messaging was difficult despite no intent to blame anyone. “This is tragic,” Dr. Kotton added.

Federal agencies and their advisors may have given Americans the impression, by approving boosters even though they were reluctant to do so, that two doses of boosters weren’t enough protection, according to experts.

“They continue inadvertently to damn the vaccine, when what they should say is, ‘It is remarkable,'” said Dr. Offit. “It’s miracle vaccin.”
