There is a preliminary report from the Israeli MOH (so far, only in Hebrew) that estimates vaccine-induced myocarditis incidence at 1:20,000 for the 16-30 group, and 1:100,000 overall. The report text says they have trouble getting good estimates of relevant myocarditis background rates - so they might be overestimating the incidence - but that they feel there is reason to take note, and have therefore published these preliminary results and submitted them to the FDA and Pfizer.

- beagle3 6y agoIt's unclear to me (and apparently to the people doing this research - they state they haven't been able to figure that out yet). It is clear, though, that not everyone gets covid, but (in Israel) essentially everyone gets the vaccine (>80% of age>16 already), so a vaccine must be significantly safer than the disease it prevents. Furthermore, the most worrying signal they remark on is that covid myocarditis seems to increase with older age, whereas post-vaccine myocarditis seems to increase with lower age. I've read a hypothesis that bits of free vaccine mRNA migrate in the blood, and if taken by heart muscle cells, will cause the immune system to potentially attack those heart cells when they actually express the S protein -- especially if there is some prior immunity (previous infection or cross immunity). I don't know enough to judge its likelihood myself. Only thing I take from reading this report is that the vaccine safety is not to be taken for granted the way it has been so far with the massive deployment in Israel.
