Killing them/putting them in hospital due to bad side effects of the vaccine (or drug interactions with their existing meds) isn’t great though either.It's a strange decision from a vaccine maker who knows the demographic for death from Covid19 are the over 80s - which makes them (or should make them) overwhelmingly their target group to be tested.
If things had gone wrong I could have seen you vehemently arguing that they were irresponsible for not fully testing their vaccine on younger volunteers first
