If you got Pfizer, your risk is lower than Moderna for myocarditis. Fairly similar to COVID-19 itself according to this paper. There is also pericarditis and cardiac arrhythmia that they covered in their original paper https://www.nature.com/articles/s41591-021-01630-0#Sec30 https://www.nature.com/articles/s41591-021-01630-0#Sec30 Unfortunately not stratified by age and sex there (what a shame when it is obviously greatest interest here, what were they thinking, like actually, what were they thinking?) but the risk should be clearly higher for COVID-19 as it is non-existent for vaccines. As such, the original paper was bad as they did not stratify by important parameters but this paper might be even worse as they do not include other complications that would significantly change the picture. I also feel wary about the method they are using - perhaps somebody could share thoughts about this? They used self controlled case series (SCCS) for IRR. I am not fully confident that this kind of analysis can be used for such data in this setting.
