Now, six months later, in
October 2021, one-quarter (27%) of U.S. adults say they have not gotten a COVID-19 vaccine, but the unvaccinated population is now disproportionately made up of those who identify as Republican or Republican-leaning, with six in ten (60%) identifying as Republican or Republican-leaning (compared to about four in ten of the U.S. total adult population
1) and just one in six (17%) calling themselves Democrats or Democratic-leaning. See Appendix figure 1 for a full demographic profile of unvaccinated adults from April to October 2021.
