  I skimmed through the study, but didn't read the whole thing. It appears that they called it vaccine related if it happened within 42 days of being vaccinated. What would the normal incidence be for unvaccinated people in a typical 42 day period? And what is the incidence for people who get infected with covid? Without those to compare with its hard to know what to think about these numbers.

  Look at this user's submission history - nothing but inflammatory political posts, almost nothing related to technology.

  This is one of the only aggregation websites yet to turn into the typical Twitter/Reddit screaming chamber, disappointing to see users actively try to push it in that direction.

  1.08 in 100,000 cases of vaccine related myocarditis (VRM), 2.16 deaths per 1,000,000.

  Hard to take much meaning away from that without understanding the risk posed by not vaccinating.

  If vaccines can prevent long COVID or "post viral syndrome," that's another potential cost benefit analysis. (which would make sense from a laymen perspective, killing k random cells seems bad, but killing N random cells seems strictly worse).

  It looks like this is part of a growing body of evidence that suggests that the risks outweigh the benefits of vaccination for young people.

  It's also worth noting that the incidence of post-vaccination myocarditis (from this study; 1.08 per 100k people) is significantly lower than the 2014 rate of myocarditis: 8.6 per 100k people [1]. Additionally, the risk of myocarditis from a covid infection is signfiicantly higher than the risk of myocarditis from the covid vaccine.

  That being said, especially since the danger of covid is much less for young people, and the risk of the covid vaccine causing myocarditis is much higher for them, there's a growing push to stop vaccinating young people against covid. I think the CDC continues to quash its credibility by trying to sweep this under the rug, rather than presenting the facts--that there is risk, and there's a cost-benefit analysis.

  20% of myocarditis ended up in deaths and heart transplantation. Young males 12-17 seems to be more affected.
