Polls found that coronavirus vaccine acceptance is at a high -- with surveys finding 80% to 82% of people say they have been vaccinated or are likely to get vaccinated. These are the highest percentages [since the vaccine rollout began] ().

The CDC reports that 77% of adults have gotten at least one vaccine dose.

Vaccinations have gone up since August, and a study by health policy research organization Kaiser Family Foundation indicates that gaps by race and ethnicity are almost eliminated -- 73% of Hispanics, 71% of white people and 70% of Black people are said to be vaccinated.

However, vaccine gaps persist across party lines -- KFF found that 90% of Democrats say they’ve gotten at least one dose of the vaccine, compared with 68% of independents and 58% of Republicans.

Only about 29% of unvaccinated workers say they would get a shot if their employer mandates it, according to the Axios/Ipsos Coronavirus Index.
