This paper essentially argues that the risk of myocarditis in under-40 males getting 2 shots is greater (perhaps much greater) than the risk of getting it from COVID. There have been similar studies before, but none (that I saw) broken down by age and sex like this.
It reads:
> Despite more myocarditis events occurring in older persons, the risk following COVID-19 vaccination was largely restricted to younger males aged less than 40 years, where the risks of myocarditis following vaccination and infection were similar. However, the notable exception was that in younger males receiving a second dose of mRNA-1273 vaccine, the risk of myocarditis was higher following vaccination than infection, with an additional 101 events estimated following a second dose of mRNA-1273 vaccine compared to 7 events following a positive SARS-CoV-2 test.
This guy made a graph of their data, which makes it a little more clear:
