Experts and health officials were already expecting vaccines to be only 50-75% effective, so this isn't new information.
That's what's so frustrating to me about the "herd immunity" discourse. Health officials have consistently said there's no way the disease is going to be eradicated, but because of the way it gets discussed, a lot of smart people have become convinced that the goal of a vaccine is to make sure nobody catches it.
