New study using Kaiser data with both Pfizer and Moderna all ages [1]. 15 cases out of 2,392,924 (0.8 cases per 1 million first doses and 5.8 cases per 1 million second doses over a 10-day observation window), of which all were men with a median age of 25 years.

While that's both vaccines, it's still quite rare especially given the large population size (2.3M people), especially considering for under 16s your risk of myocarditis is 37x more likely if you get Covid [2].

Thanks for the data.

In a world where people like to talk about their opinions, it's great to have some form of foundation. When I speak to folks and can talk about these details it often sways opinions on those who aren't at the extremes. I wish more people shared data and the foundation for their opinion.

What's missing is how many people you'd expect to have some myocarditis in absense of covid or the vaccine.

I doubt that it would be 0/2M
