Americans’ willingness to be vaccinated against COVID-19 has jumped markedly since the Pfizer-BioNTech and Moderna jabs have been authorized for use by the FDA, according to a new poll.

According to the USA Today/Suffolk University Poll, 46 percent said they will take the vaccine as soon as they can — almost double the 26 percent who were ready to get the shot as soon as possible in a USA Today poll in late October.

In the new poll, 32 percent of the respondents said they would wait for others to get the shots before they do so themselves.

“We need to get control of this virus, and that would be doing my part,” said Susan Sadule, 59, a retiree from Easton, Pennsylvania, who was polled.

“From what I’ve read, it’s going to take about 75 percent of the nation taking the vaccine in order to create herd immunity — and quite frankly, I don’t want to live in a pandemic the rest of my life,” said Lisa McAlister, 48, a registered nurse from Grove, Oklahoma.

Those most reluctant to get a vaccine remain unpersuaded. In October, one in five said they wouldn’t take the shot — now or later. An identical 20 percent said that in the latest survey.

Both polls surveyed 1,000 registered voters and have margins of error of plus or minus 3.1 percentage points.
