Say what, 43 and chuboy? Are you really saying that when the CDC says: "CDC and its partners are investigating these reports to assess whether there is a relationship to COVID-19 vaccination.", the CDC is not considering whether there may be a causal connection between the vaccinations and Myocarditis/Pericarditis? C'mon.
Of course they are, as I said earlier myocarditis/pericarditis is KNOWN to be associated with mRNA vaccines, but at extremely low rates. Over the whole age range it's negligible occurrence, if you are male between 16 and 30 the rate is highest with 32 cases per million observed, however that's not saying all observed are caused by the vaccine, but it would be certain some are. The actual rate of myocarditis would be difficult to know, like trying to accurately assess how many people actually get flu each year. All that really matters is the symptomatic cases, and death rate. Which the death rate for myocarditis post vaccination seems extremely low, pretty much on one hand type numbers (worldwide). So you get warned when you take an mRNA vaccine that heart issues could occur, are extremely rare, but if you do get it, go to hospital and they fix it with no long term issues.
