• Overall, 30% of respondents indicated that they had received a COVID-19 booster shot. 

• Older respondents are much more likely than their younger counterparts to have received a booster shot, with respondents over age 65 four times as likely as Gen Z respondents (ages 18-24), by 53% to 13%. 

• Democrats are more likely than Republicans to have received a booster shot (33% vs. 27%). However, partisanship is a far less strong predictor of having received a booster shot – either nationally or comparing Democratic and Republican-leaning states, contingent on having previously been vaccinated – than of having been vaccinated in the first instance. 

• As education increases, the probability of having received a booster increases (from 22% among respondents with a high school education or less to 46% among their counterparts with graduate degrees). 

• We find only small differences in the probabilities of being vaccinated or having received a booster, as well as in respondents’ reasons for getting a booster, before vs. after the WHO Omicron announcement. 

• Nearly half (47%) of previously vaccinated respondents are booster hesitant or resistant.
