The 74% of U.S. adults vaccinated against COVID-19 was virtually unchanged in October, roughly 10 months after shots were first widely administered to the general public. The total percentage either vaccinated or planning to be is also steady, at 80%.

As they have each month, most of the 20% of U.S. adults who are not vaccinated and don’t plan to be describe themselves as unlikely to change their mind. Just 16% of the vaccine-resistant group in October, representing about 3% of all adults, say they are likely to agree to be vaccinated in the future.

By comparison, in the spring, an average 21% of unvaccinated adults described themselves as likely to change their minds. But as the vaccination rate has risen, the unvaccinated group has dwindled to those most hardened in their views. Any future increases could depend on how effective the Biden Administration’s recently issued vaccine mandates are at convincing reluctant workers to get the jab.
