“so I would say that if they admitted to 10-15 reinfectivity it’s probably higher”
probably not because based on our understanding of biology that doesnt make sense.
Again the whole point of vaccines is to build immunity against the virus. If people who had the ACTUAL virus dont have immunity, then a vaccine will obviously not help.
(Sure a few for whatever reason wont have or maintain anitbodies, much like some get flu vaccine and yet get the flu. but for thae VAST VAST majority once you’ve had it you shouldn’t be able to get it again .
