Overall adult vaccination rates have been relatively steady over the past year. The latest COVID-19 Vaccine Monitor finds that nearly eight in ten adults (77%) say they have gotten at least one dose of a COVID-19 vaccine, including about half who say they are fully vaccinated and also received at least one booster dose (47%), about a quarter who have been fully vaccinated but have not gotten a booster (26%), and a small share who are partially vaccinated (3%). Twenty-three percent remain unvaccinated, the vast majority of whom say they will “definitely not” get the COVID-19 vaccine (88% of unvaccinated, or 21% of all adults).
