Looking at that study for Pfizer and Moderna it's a slightly increased risk of myocarditis and shoulder injury at the site of injection. That's it. All other side effects they either didn't have enough evidence for or found that the evidence explicitly rejects a causal relationship.

Myocarditis is a pretty serious thing [1], so even a slight increase in risk in young people makes it pretty much a no-no to vaccinate them.

  Fully agree, so one more reason to get vaccinated, as getting myocarditis from Covid is far more common. https://newsroom.heart.org/news/myocarditis-risk-significantly-higher-after-covid-19-infection-vs-after-a-covid-19-vaccine https://newsroom.heart.org/news/myocarditis-risk-significant...

    That only follows if the vaccine prevents infection.

      No it doesn't. The study was the outcome of the vaccine irrespective of what happens after you get the vaccine. Get a full covid infection? Still counted. Get no infection? Still counted. Still lower in the end.

      The vaccines significantly reduce the severity and duration of covid. Reduced severity translates to a lower risk of complications, including myocarditis. It doesn't have to prevent infection completely to protect you.

  Given that study you'd expect over an extra 10 years somewhere around 10k excess deaths from the vaccine in the US. That's probably very generous. That's tiny versus mortality rates from COVID.

    Except of course it hits those who would not have had any problem with COVID in the first place: young people. Personally, I'd like that explained to me before the shot.

And better still, the severity of postvaccination myocarditis is much less than post-infection myocarditis. However, the prognosis for myocarditis after COVID-19 vaccination appears to be much less severe. In a study of nearly 4 million residents of Hong Kong, only one death occurred (1%) among 104 cases of postvaccination myocarditis, compared with 84 deaths (11 percent) among 762 cases of viral infection-related myocarditis (HR 0.08, 95% CI 0.01-0.57). In a surveillance study of cases of myocarditis related to COVID-19 vaccination in the United States reported to VAERS, among 484 hospitalizations there were no deaths, and evidence of ongoing myocarditis at follow-up cardiac MR was uncommon (13 percent)
