As vaccines for COVID-19 enter review for emergency use by the FDA, the share of Americans who say they plan to get vaccinated has increased, as the public has grown more confident that the development process will deliver a safe effective vaccine.

Still, the U.S. public is far from uniform in views about a vaccine.

60% of Americans say they would definitely or probably get a vaccine for the coronavirus, if one were available today. 39% say they definitely or probably would not get a coronavirus vaccine, though about half of this group says it’s possible they would decide to get vaccinated once people start getting a vaccine, and more information becomes available.

Yet 21% of U.S. adults do not intend to get vaccinated and are pretty certain more information will not change their mind.
