The survey of 1,715 U.S. adults, which was conducted from July 13 to 15, found that a full 62 percent of those who’ve been vaccinated would receive another jab if possible, while just 18 percent would decline. Another 20 percent are not sure.

The emerging interest in COVID boosters comes as the hyper-contagious Delta variant drives a “pandemic of the unvaccinated” in state after state, and as the virus’s accelerating spread among unvaccinated Americans occasionally spills over into the vaccinated population in the form of “breakthrough cases.”…

While 85 percent of vaccinated Americans say Delta poses a “serious risk” to either “all Americans” (32 percent) or “unvaccinated Americans” (53 percent), for instance, only half of unvaccinated Americans (50 percent) say the same, with just 17 percent specifying that it’s the unvaccinated who are at risk. Another 30 percent of the unvaccinated, meanwhile, say Delta “doesn’t pose a serious risk to any Americans.”
