Thirty-three percent of those surveyed say they would feel safe eating indoors at a restaurant a few weeks after their second COVID dose or earlier, according to the Harris Poll survey conducted Friday through Sunday. By comparison, 29% of those polled in January said they would be comfortable dining out no later than a few weeks after the second dose.
