Harris was asked whether she would take a vaccine if one were approved by the Trump administration, during her head-to-head with Vice President Mike Pence on Wednesday.

“If the public health professionals, if Dr. Fauci, if the doctors tell us we should take it, I’ll be the first in line to take it, absolutely,” she said. “But if Donald Trump tells us we should take it, I’m not taking it.”

Pence criticized Harris’ comments and told her: “The fact that you continue to undermine public confidence in a vaccine, if the vaccine emerges during the Trump administration, I think is unconscionable.”

While the Republican pushed back against Harris’ remarks, polling suggests her view reflects public opinion.

In an Axios/Ipsos survey, conducted among 1,075 U.S. adults from September 24 to 27, people were asked how likely they would be to take a first generation COVID-19 vaccine in a range of scenarios.

In a situation in which their doctor said a vaccine was safe, 62 percent said they were likely to take it. Then asked how they would react if Trump said it was safe, 19 percent said they would be likely to take it.

In an ABC News/Ipsos poll, conducted among 528 adults September 18 to 19, most of those asked said they did not trust Trump to confirm the safety and effectiveness of a potential coronavirus vaccine.

Asked how much confidence they had that he could do so, 53 percent said none at all.

An NBC News/SurveyMonkey poll found that a majority of those asked if they trust what Trump has said about a vaccine for the coronavirus, said they did not.

Of 36,551 respondents, asked online from September 7 to 13, 52 percent said they did not trust what Trump had said.

Meanwhile, separate polling has reported a fall in the proportion of people who have said they would get a COVID-19 vaccine.

Trump has long spoken of his push for a vaccine to be ready, and Pence suggested during Wednesday’s debate that one will be ready in “record time” and before the end of the year.

The president previously said the military could be used to help deliver 200,000 doses of a vaccine per day.

Several Democratic lawmakers have questioned Trump’s word alone being sufficient to declare the vaccine safe or effective.

Newsweek has contacted the White House and Harris for comment.
