Well, I’m just confused by the reaction because it’s not rational and, you know, I don’t want to accuse anyone else of having mental illness or emotional problems but these people are not thinking as scientists think. So you can’t simultaneously say that the vaccine is very effective and by the way, I see no reason to doubt that claim. It seems very effective - and, yet, at the same time say that once you have been vaccinated you are very concerned that you might be infected by people around you who are not wearing masks. That leaves a couple questions unanswered. The first that’s never asked, which is how exactly do we know that masks are very effective in preventing the transmission of Covid-19. I don’t think that we do know that and if we do, I would love to see the study that shows that. But more to the point, if you've been vaccinated, why are you concerned that you’re going to be infected by someone who is not wearing a mask? It doesn’t make any sense. You clearly don’t think the vaccine works if you're worried about that.
