Another finding: Four in 10 Americans haven’t changed their mask-wearing habits since the Centers for Disease Control and Prevention dropped mask requirements for vaccinated people in mid-May. “As the CDC has loosened its mask restrictions for people who have had the vaccine, we're finding more of the unvaccinated are using that as an opportunity to take off their masks as well, because you can basically blend in with the crowd,” Patrick Murray, director of the Monmouth University Polling Institute, told USA TODAY. Of those that have been vaccinated, 41% are wearing masks as often as they did before the new guidance, according to the poll. Among the 1 in 5 Americans who said they won’t get vaccinated, only a quarter reported wearing their mask as often as in the past, and nearly half reported wearing a mask only rarely during the pandemic.
