Americans who have gotten vaccinated and boosted against coronavirus are the most “personally concerned about the coronavirus threat,” according to a Rasmussen poll released on Friday.

Among unvaccinated Americans, only 36 percent are concerned about coronavirus, including 13 percent who are very concerned. Vaccinated respondents are much more wary, with 75 percent saying they are worried about coronavirus, including 41 percent who are very concerned.

Eighty-one percent of those who have gotten the booster say they are still concerned about the coronavirus threat, “including 48 percent who are very concerned.” The survey was conducted with 1,000 American adults on January 2-3 during an ongoing spike in omicron variant cases nationwide.

Overall, 64 percent of respondents say they are “personally concerned about the coronavirus threat,” including 33 percent who are “very concerned.” In contrast, 33 percent are not worried, including 12 percent who are “not at all concerned about COVID-19.”
