A new poll has found that Americans are sharply divided by household over vaccination status, with 77 percent of vaccinated adults saying everyone in their household is vaccinated and a similar share (75 percent) of unvaccinated adults saying no one they live with is vaccinated. Sixty-seven percent of Democrats reported living in households where everyone had been vaccinated, compared with 39 percent of Republicans. Ten percent of Democrats said they lived in homes where no one had been vaccinated, compared with 37 percent of Republicans, according to the poll by the Kaiser Family Foundation, which has been tracking the public’s attitudes toward and experiences with vaccinations. Overall, half of U.S. adults live in a fully vaccinated household and one in four lives in a completely unvaccinated household. The remainder, about one in five adults, lives in a household occupied by both vaccinated and unvaccinated people, including children under 12 who are not currently eligible to receive a vaccine.
