More Americans are willing to get a covid-19 vaccine, new polling suggests.

For the first time in their poll, a slight majority of Americans (55%) have either gotten at least one dose of the vaccine (18%) or are looking to get it as soon as possible (37%).

As of Friday, 47.2 million Americans have received at least one dose of the Moderna or Pfizer/BioNTech vaccines, while 22 million have been fully vaccinated with two doses.

Of the people who still wanted to wait and see, 26% said that they would be more willing to get a vaccine if it only required one dose.

Real-world data continues to support the safety and efficacy of both mRNA vaccines, however, and none of the vaccines available are able to give people covid-19, since they don’t contain the actual coronavirus.

About 15% in the poll said they would “definitely not” get vaccinated, while another 7% said they would only get a vaccine if it was required for work, school, or other activities—numbers that haven’t changed much since December.
