>Does anybody know if the J & J vaxx (theoretically) causes similar myocarditis/heart problems<
The J&J jab put me in the hospital. Arrhythmia, sky high BP and pulse rate beat the heck out of myocarditis.
There was no explanation except they drew blood every hour to check for clotting, yet not a peep from anyone as to why. Lots of people knew but no one was talking about it.
