> Post COVID-19 infection was not associated with either myocarditis (aHR 1.08; 95% CI 0.45 to 2.56) or pericarditis (aHR 0.53; 95% CI 0.25 to 1.13). We did not observe an increased incidence of neither pericarditis nor myocarditis in adult patients recovering from COVID-19 infection.

But also your source is kind of bad. It doesn't have an unvaccinated control group, so from that research there's no way to know if what they found was virus or vaccine related. But they did find an age and sex based correlation which lines up with other sources saying the vaccines are bad for young men:
> The risk of COVID-19 vaccine-associated myocarditis was higher in men younger than age 40 after a first dose of an mRNA vaccine or after a second dose of any of the 3 vaccines.
