The answer is a moving target. More people get sick, more people get vaccinations, and possibly people's immunity wanes over time. But, one snapshot in time was 83%: https://www.aabb.org/news-resources...that-83-of-americans-have-covid-19-antibodiesHow many Americans still don't have any immunity (via infection and/or vaccine)? I've seen estimates that ~60% of Americans have natural immunity, but I can't find anything showing how that overlays with vaccinations.
