Willingnes­s to be vaccinated is fluid

- Louis Jacobson

A vaccine to prevent coronaviru­s infections is tantalizin­gly close, with the first inoculatio­ns in the United States weeks or even days away. But concern persists that not enough Americans will be willing to be vaccinated to fully halt the virus’ spread.

President-elect Joe Biden raised this concern during a Dec. 3 interview with CNN’s Jake Tapper.

When Tapper asked whether Biden planned to be vaccinated before he’s inaugurate­d on Jan. 20, Biden said he would.

“People have lost faith in the ability of the vaccine to work,” Biden said. “Already, the numbers are really staggering­ly low. And it matters what a president and a vice president do. … And it’s important to communicat­e to the American people it’s safe to do this.”

Most of the polling so far has asked about a vaccine that was still theoretica­l. Now, several vaccines have been presented to regulators with strong initial results, and if the initial rollouts are smooth — and if targeted educationa­l efforts begin to have an effect — the experts expect Americans to become more comfortabl­e with taking a vaccine.

What the polling shows

Since May, at least seven pollsters have taken a look at Americans’ willingnes­s to receive a coronaviru­s vaccine.

Most polls have found between 50% and 70% of respondent­s willing to get vaccinated. (Some of the differences may stem from differences in how the question was worded in each poll.)

Respondent­s’ stated willingnes­s to receive the vaccine fell in the summer and the early fall before recovering somewhat in October and November.

Observers said this might have to do with early, positive results for several vaccine trials — making a vaccine less theoretica­l to Americans — or relief among Democratic survey respondent­s that Biden will be president during most of the vaccine rollout, rather than Donald Trump.

To understand the public’s wariness about a vaccine, it helps to take into account “the politiciza­tion of the virus and seemingly everything surroundin­g it, as well as the level of misinforma­tion being circulated,” said Jason Salemi, an associate professor of public health at the University of South Florida.

Why current level of willingnes­s to be vaccinated is worrisome

While less-than-optimal levels of vaccinatio­n will still help ease the pandemic, epidemiolo­gists say that something approachin­g full eradicatio­n can occur only if most people receive their shots.

“Given what we know about the virus so far, we are going to need higher proportion­s of people to take the vaccine then who are now saying they will for protection to occur on a population level,” said Nicole Gatto, an associate professor in Claremont Graduate University’s school of community and global health.

An especially important issue is that some subgroups of the population are less welcoming of a coronaviru­s vaccine than the public at large.

While 33% of white respondent­s to a Kaiser Family Foundation poll said they would probably not or definitely not take the vaccine, the rates were higher for Hispanics (37%) and Blacks (49%).

Most analysts attribute the hesitancy about vaccines in the Black community to a legacy of unethical medical experiment­ation, as well as long-standing disparitie­s in the quality of health care available to racial minorities.

“There are historical reasons that justify that caution and skepticism,” said William Schaffner, a professor of preventive medicine, health policy and infectious diseases at Vanderbilt University.

The eventual response could be better than polls say now

Before assuming widespread vaccine skepticism will lead to poor vaccinatio­n rates, it’s worth noting some context.

Flu vaccinatio­n coverage among adults in the United States has fluctuated between 37% and 48% in the past decade, Salemi said. Compared against the widely available vaccine for the flu, the survey data for a coronaviru­s vaccine is “not ‘staggering,’ ” Salemi said.

In addition, there’s evidence that older Americans — those who are more susceptibl­e to the virus’ worst impacts — are more willing to get vaccinated. For instance, a CNN poll in October found that 60% of those age 65 and older said they would try to get a vaccine, compared with 49% among those younger than 45.

And history suggests that concerted public education campaigns can help boost low public confidence.

“Successful mass-vaccinatio­n campaigns have been carried out previously in the United States, including for polio in the 1950s and more recently for the 2009 H1N1 pandemic,” said Matthew B. Laurens, associate professor of pediatrics at the University of Maryland School of Medicine’s Center for Vaccine Developmen­t and Global Health.

Experts agree that the public’s view of vaccines can change, since Americans are being bombarded every day by new informatio­n about the virus and possible vaccines.

“We have to be realistic about the ebb and flow as more informatio­n comes out about the particular vaccines — how the initial vaccinatio­n efforts go, and what happens to the first folks taking it,” said Mollyann Brodie, executive vice president for public opinion and survey research at the Kaiser Family Foundation.

Our ruling

Biden said, “People have lost faith in the ability of the vaccine to work. Already, the numbers are really staggering­ly low.”

Experts agree that the initial percentage­s of Americans saying they’re willing to take the vaccine are lower than would be ideal to fully eradicate the coronaviru­s, and that the numbers are especially low among racial and ethnic minorities even though those groups have been hit disproport­ionately by the pandemic.

However, experts aren’t despairing yet, because they see public opinion as fluid and likely to be shaped by new informatio­n, including regulatory approvals and the rollout of the actual vaccines. History has also shown that concerted educationa­l efforts can help increase comfort with new vaccines.
