i dont understand this irrational fear of what COULD happen in 3, 20 or 40 years. But my whole live has been medicine and science. so to me its not a question. I can understand some of the concerns to a degree. the virus doesnt re write your genetic code. attack any organ system. THE only current thing that is making the news is their are young/ teenagers getting vaccine and having some myocarditis. but it is an insanely small number. and vast majority resolves without any treatment
