Do you have any source for the claim that myocarditis is less severe after the vaccine than after infection? I was under the impression it was the opposite due to most infections remaining in the airways.
I guess I formulated it in a confusing way. I don't know whether myocarditis caused by vaccine is more or less severe vs. myocarditis caused by COVID-19.
What the article references is a report that 76% of vaccine-associated myocarditis events were described as mild [0].
> A total of 76% of cases of myocarditis were described as mild and 22% as intermediate; 1 case was associated with cardiogenic shock. After a median follow-up of 83 days after the onset of myocarditis, 1 patient had been readmitted to the hospital, and 1 had died of an unknown cause after discharge. Of 14 patients who had left ventricular dysfunction on echocardiography during admission, 10 still had such dysfunction at the time of hospital discharge. Of these patients, 5 underwent subsequent testing that revealed normal heart function.
We also know that long term effects of COVID-19 overall i.e. not only myocarditis are not always mild and can be debilitating even for people below 40, even after mild COVID-19. See my reply here: https://news.ycombinator.com/item?id=29564815
