Officials: Scale back on booster planning

- BY SHARON LAFRANIERE AND NOAH WEILAND

WASHINGTON — Top federal health officials have told the White House to scale back a plan to offer coronaviru­s booster shots to the general public later this month, saying regulators need more time to collect and review all

the necessary data, according to people familiar with the discussion.

Janet Woodcock, acting commission­er of the Food and Drug Administra­tion, and Rochelle Walensky, who heads the Centers for Disease Control and Prevention, warned the White House on Thursday that their agencies may be able to determine in the coming weeks

whether to recommend boosters only for recipients of the Pfizer-BioNTech vaccine — and possibly just some of them to start.

The two health leaders made their argument in a meeting with Jeffrey Zients, the White House pandemic coordinato­r. Several people who heard about the session said it was unclear how Zients responded. But he has insisted for months that the White House will always follow the advice of government scientists, wherever it leads.

Asked about the meeting, a White House spokespers­on on Friday said, “We always said we would follow the science, and this is all part of a process that is now underway,” adding that the administra­tion was awaiting a “full review and approval” of booster shots by the FDA as well as a recommenda­tion from the CDC.

“When that approval and recommenda­tion are made,” the spokespers­on, Chris Meagher, said, “we will be ready to implement the plan our nation’s top doctors developed so that we are staying ahead of this virus.”

Less than three weeks ago, President Joe Biden said that, contingent on FDA approval, the government planned to start offering boosters the

week of Sept. 20 to adults who had received their second shot of the Pfizer-BioNTech or Moderna vaccine at least eight months ago. That would include many health care workers and nursing home residents as well as some people older than 65, who were generally the first to be vaccinated. Administra­tion officials have said that recipients of the single-dose Johnson & Johnson vaccine would probably be offered an additional shot soon as well.

Biden cast the strategy as another tool that the nation needed to battle the highly contagious delta variant, which has driven up infection rates, swamped hospitals with COVID-19 patients and is now leading to an average of more than 1,500 deaths a day for the past week, according to the New York Times database. “The plan is for every adult to get a booster shot eight months after you got your second shot,” he said Aug. 18. “It will make you safer, and for longer. And it will help us end the pandemic faster.”

But the announceme­nt of a late September target date for starting the booster campaign set off alarm bells inside the FDA — apparently playing a role in decisions by two of its top vaccine regulators, announced this week, to leave the agency this fall.

Both Woodcock and Walensky helped draft the plan and publicly endorsed it. Some public health experts have said that by doing so, they increased pressure on scientists weighing the evidence for boosters within their respective agencies to go along with the administra­tion’s strategy.

“Now those agencies are in a box,” said Dr. Steven Joffe, a professor of medical ethics and health policy at the University of Pennsylvan­ia. “We want doctors and scientists and the public to trust in the recommenda­tions and decisions that are made, to be able to point to the FDA and CDC doing their due diligence.”

Privately, Woodcock had argued that it was risky to set a firm date for a booster rollout before regulators had a chance to thoroughly review the data, some of which had yet to be submitted by the vaccine manufactur­ers, and decide whether shots were safe and necessary, according to several people familiar with the discussion­s.

And since the White House announced the booster plan in mid-August, they said, new hurdles appeared.

Among the reasons for delaying is that regulators need more time to decide the proper dosage for a possible third Moderna shot. The company’s applicatio­n asking the FDA to authorize a booster shot contains insufficie­nt data, one federal official familiar with the process said. Other data expected from Johnson & Johnson has not been delivered.

Nor has the raw data that the FDA has been seeking from Israel, which is already giving boosters to everyone 12 and older. Israeli officials say their data shows that the potency of Pfizer’s vaccine wanes over time against severe disease and hospitaliz­ation but that a third shot bolsters protection significan­tly. The FDA wants to see the underlying data to make sure it backs up summaries that the Israeli government has provided.

Narrowing the booster plan could confuse the public and create a perception that federal vaccine policy is in some degree of disarray. But some public health experts will most likely welcome it.

They have been arguing strenuousl­y that the administra­tion lacks the data to justify a broad rollout of extra shots and should instead concentrat­e on vaccinatin­g the roughly 25% of Americans who are eligible for shots but remain unprotecte­d. And some have said that senior Biden officials, including the leaders of health agencies, wrongly cornered regulators by announcing a strategy before they could conduct a full review.

Regulators are only beginning to review critical data that will help them determine if and how boosters should be given. Pfizer completed its booster applicatio­n to the FDA last week, and Moderna said Friday that it had just completed its own.

Various studies have shown that the potency of the Pfizer-BioNTech and Moderna vaccines ebbs against infection over time but suggest that the vaccines continue to offer robust protection against severe illness and hospitaliz­ation.

But Dr. Vivek Murthy, the surgeon general, said in an interview Thursday that a few studies have suggested a dip in protection against severe disease over time. “Our feeling was that if we waited several more months, we would see protection against hospitaliz­ations and deaths break down,” he said.

In an interview published Thursday on WebMD.com, Woodcock echoed that view, saying that the trend of breakthrou­gh infections has led health officials to believe at some point “we are going to see hospitaliz­ations and more serious disease” among fully vaccinated people. When that happens, she said, “we want to be ready” with the booster plan.

Some Americans are already getting booster shots before FDA approval: More than 1 million fully vaccinated people have received an additional dose since mid-August. The agency authorized vaccines for some people with weakened immune systems on Aug. 12; it is unknown how many of the people who have gotten extra doses are in that group.
