The share of Americans not vaccinated against COVID-19 who were self-identified Republicans rose from 42 percent last April to 60 percent in October, according to surveys by the Kaiser Family Foundation. During that period, the share of the unvaccinated who were Democrats fell from 36 percent to 17 percent. Misinformation has encouraged distrust in vaccines among some people, even as the total number of vaccinated Americans has grown.
