Do you have a source on the vaccine being bad for the heart? I’m curious to learn about it

Yeah there’s many sources, it’s a pretty well accepted fact that they can cause myocarditis, can also cause clots leading to heart attack as well, Pfizer’s own safety data discloses it, although it is generally rare. 

Then there are other ways it may harm the heart that are more controversial without as much consensus or data.
