Just 11% of people who remain unvaccinated say they definitely will get the shot, while 34% say they definitely won't, according to the poll by The Associated Press-NORC Center for Public Affairs Research. That leaves a large swath of Americans in the middle who might still roll up their sleeves — including 27% who say they probably will and 27% who say they probably won't — if someone credible addressed their concerns. That's where National Institutes of Health immunologist Kizzmekia Corbett comes in... Overall, the AP-NORC poll found about 1 in 5 American adults say they probably or definitely won’t get vaccinated, compared to about a third in January, when the shots were just rolling out. Black Americans likewise are becoming more open to the shots, with 26% now saying they definitely or probably won’t get vaccinated compared with 41% in January. That’s similar to the 22% of Hispanic Americans and white Americans the poll found unlikely to get vaccinated. Among Asian Americans, just 9% say they definitely or probably won’t get the shots.
