In polls, many conservatives continue to voice vaccine skepticism, as do some conservative politicians and opinion leaders. A Marist/NPR/PBS/survey in late June found that half of Trump supporters say “they won’t get a shot, the highest of any group surveyed.”
KFF, a nonprofit focused on health policy, reports that vaccination rates in counties that supported Trump in 2020 lag behind rates in counties that carried by Biden. A three percentage-point gap in early April widened to nearly 12 points by early July.
KFF finds that vaccination rates among some other groups are also lagging. In a June survey, it found the largest single reason—cited by 20% of all unvaccinated adults—to be “concerns over possible side effects.” Those findings were largely unchanged since January.
Almost all recent U.S. hospitalizations and deaths associated with COVID-19 have been among unvaccinated people.
