Lol, antivaxers got on here too. Before posting nonsense do your research. Serg had a pre existing heart issue which was diagnosis when he was 15 so it's likely linked to that (as he has had minor complications since). Medical experts (not keyboard antivax experts) have confirmed that it is highly likely Eriksen (as other sports people, including MVF - rest his soul) had an undiagnosed pre existing heart issue (which is now why he can't get insurance to play again). To say that both completely different incidents are the result of vaccines is absolutely obsurd. I'm assuming you declined the vaccines? Unless your username indicates you are only 13, in which case I would ask your parents to teach some sense into you
