It's hard to talk about the COVID vaccine in the context of other vaccines. The history of our attempts at developing traditional vaccines for this type of virus goes back 50 years, and we've been very unsuccessful at it, not for lack of trying. I don't think it's unreasonable to believe that we wont ever be able to develop a vaccine for this type of virus in the same manner that we have for e.g. polio.
