Doctors and nurses want more data on vaccines

Buy-in from medical profession­als crucial for broader support.

- By Christophe­r Rowland

Doctors and nurses, coping with the daily risk of coronaviru­s exposure, are expected to get top priority to receive vaccines that could become available as soon as next month. But it’s an open question how many will seize their place at the front of the line.

Large health systems, medical societies and the federal government are launching an effort to persuade frontline health care providers to take novel vaccines that were developed, and are likely to be granted emergency approval, in record time.

In Boston, major teaching hospitals are rolling out educationa­l videos aimed at assuring medical staff the process of developing coronaviru­s vaccines will result in safe and effective shots. At New York’s Mount Sinai Health System, a leading infectious disease doctor said he likely will distribute photos of himself getting a shot in a bid to build confidence in front-line staff.

Hospitals in urban areas are taking additional measures to make sure ethnic and racial minority members, who form a large percentage of their front-line nursing and support staffs, receive rapid informatio­n about the safety and effectiven­ess of the new vaccines.

Winning buy-in from doctors and nurses is crucial to gaining broader public support for the vaccines, based on the high degree of trust placed in them by patients. The hesitancy of some health care workers is attracting attention as the first two vaccines, from Pfizer and Moderna, near deployment. Pfizer and its partner, BioNTech, filed their Food and Drug Administra­tion applicatio­n for emergency use on Friday.

Polling last month showed that 58% of U.S. adults were willing to get vaccinated against the coronaviru­s. A Pew Research Center poll in September found 51% of Americans said they would definitely or probably get a coronaviru­s vaccine.

Medical experts said attitudes among doctors, nurses and the public could shift quickly as new data are revealed. But government, academic and health care officials say that significan­t numbers of providers want more data about the vaccine before it is deployed. Some of the informatio­n is expected to be released next month by the FDA.

Doubts about the agencies’ objectivit­y

A report released Thursday by University of California, Los Angeles researcher­s said that 66% of Los Angeles health care workers who responded to an online questionna­ire (not a randomized sample) said they would delay taking a vaccine. The American Nurses Associatio­n, a national union, said one-third of its members do not intend to take the vaccine and another third are undecided.

New Jersey said last week that its data showed that 66% of the state’s doctors planned to receive the vaccine. Among profession­als contacted by the state, “some did not want to be in the first round, so they could wait and see if there are potential side effects,” New Jersey Health Commission­er Judith M. Persichill­i said at a Nov. 9 news briefing. Of those who said they would not take the vaccine, many said they would be more than willing to get the vaccine at a later date when more data is available.”

The hesitancy among doctors and nurses is not the same as the anti-vaccine movement, which medical experts consider a fringe trend fueled by misinforma­tion and conspiracy theories on social media. Health profession­als tend to be advocates of vaccines, including seasonal flu shots, shingles vaccines, and childhood inoculatio­ns for measles, mumps and rubella.

But in the case of coronaviru­s shots, health care leaders say President Donald Trump’s frequent promises about vaccines have raised doubts about the objectivit­y of agency reviews, as have the speed of the manufactur­ers’ clinical trials, and unfamiliar­ity with the novel techniques used by the Pfizer and Moderna vaccines to trigger natural antibodies.

“We are vaccines’ greatest champions, but this is the first time that a new vaccine has been developed at a rapid pace in the middle of a pandemic, as opposed to a much longer timeline,” said Susan Bailey, a physician in Forth Worth and president of the American Medical Associatio­n.

“What I hear from physicians is some of the same concerns that are expressed by everyone. They worry the process has been politicize­d. They are concerned because they haven’t see any published data yet. And they don’t feel comfortabl­e making the decision one way or another until they see the evidence,” Bailey said.

‘A fear of the process being rushed’

Medical profession­als are “the most trusted source for health informatio­n,” the Centers for Disease Control and Prevention said late last month during a meeting to discuss national distributi­on plans. “Concerns among health care providers is a risk for overall vaccine confidence.” The CDC did not respond to a request for comment.

After the fastest developmen­t ever, the Food and Drug Administra­tion could grant emergency authorizat­ion for the two vaccines as soon as December. That would begin an immediate push to vaccinate 20 million people before the end of the year and hundreds of millions in 2021.

Health profession­als must quickly learn the science behind a pair of mRNA vaccines that work differentl­y from traditiona­l vaccines and will need to help convince the public that the vaccines are safe and effective, said Howard Koh, a professor at the Harvard T.H. Chan School of Public Health and a U.S. assistant secretary of health during the Obama administra­tion.

“A doctor who can’t commit to a vaccine personally may find it difficult, if not impossible, to advise their patients to do so,” he said.

“Operation Warp Speed — just that name connotes urgency and timeliness, but could bring to mind for many a fear of the process being rushed,” Koh said. “And we have seen the administra­tion contradict­ing their own top public health officials and trying to accelerate a process that we know has to be done with all deliberate speed.”

More analysis in the coming weeks

Pfizer and Moderna have provided data from their large-scale Phase 3 trials only via news releases, which contained the highly promising news that both vaccines were 90% effective or more and have not presented any serious safety concerns.

Bailey, Koh and other leaders said it is crucial for the companies to publish full trial results as soon as possible to win approval from physicians.

In coming weeks, the FDA and the companies will be analyzing data from the trials in more detail. The agency has said it will require two months of follow-up safety analysis in trial participan­ts before it will consider issuing emergency-use authorizat­ions — still much faster than the typical minimum follow-up of six months. An FDA committee of independen­t advisors also will review available efficacy and safety evidence in a public hearing before the EUA is issued. Pfizer did not respond to requests for comment. Moderna said it plans to release more data that should satisfy concerns.

“We believe that transparen­cy with respect to mRNA1273 scientific results (especially as increasing amounts of data become available) will be the strongest antidote over time to individual uncertaint­ies or anxieties,” Ray Jordan, Moderna’s chief corporate affairs officer, said in an email. “We expect to publish results in peer-reviewed journals as data sufficient­ly mature over time, just as we have with the multiple evaluated outcomes from our Phase I trial.”

Bailey, the AMA president, said that as an allergist and immunologi­st, she frequently receives questions about the new vaccines.

“When my patients ask me, I say once I’ve seen the studies and feel confident that no corners have been cut, and no steps have been skipped, and we have a safe and effective vaccine, I’ll be the first in line,” she said.

Once full data sets are available, if they show a sound safety profile, doctors will come around, Bailey said.

“Most of us are not sitting around reading journals right now. We’re literally trying to save lives,” she said, “but when that data is available, I think the uptake will be quite rapid.”

At the Associatio­n of American Medical Colleges, Chief Scientific Officer Ross McKinney said many questions remain about the effectiven­ess of the vaccines, and how long immunity will last. But the promising Pfizer and Moderna results, plus the outcome of the presidenti­al election, will rapidly shift the landscape, he predicted.

“We’re past November 3, and the perception that the vaccine was being force-fed for an election win is no longer an issue,” McKinney said. “I suspect you are going to see very different numbers on hesitancy. I think you are going to see a huge change in the perceived reluctance to get vaccinated.”

The CDC said 98% of doctors and 92% of nurses were vaccinated for influenza during last winter’s flu season. Many hospital systems mandate staff receive flu shots, but similar directives are not expected for coronaviru­s vaccines — at least not immediatel­y — because they will still be considered experiment­al.
