you realize that this was someone who they state was healthy. and that he was scheduled for a BOOSTER. which means he ALREADY got the vaccine. not that day, but there is definitely the possibility that this guy DID die from the vaccine, from his FIRST vaccine that he got a few weeks earlier... which may have caused heart inflammation which caused him to die during playing tennis for example.
thats why they stress that it was before he got the shot ppl shouldnt realize its from the vaccine
