The parents of one of my sons friends were naïve enough to go and get the jab, and to do it at the same time (same batch). One got myocarditis, the other pericarditis. They told me that particular batch had over 500 serious adverse event reports. They will likely receive no compensation and will probably die much more prematurely than they otherwise would have. They trusted the authorities, not sure if they've properly learned the lesson yet though.
