Paul Offit of the Perelman School of Medicine said the U.S. may still be able to reach some form of herd immunity for COVID-19. “If you define herd immunity as a critical decrease in this virus’ ability to spread from one person to another, so much so that you have a dramatic decrease in hospitalizations and deaths, I think the answer is yes. But in order to do that, we’re going to have to figure out a way to vaccinate the unvaccinated,” he said.
