Rather than CHERRY-PICKING the largest reported Covid vaccine (CV) ROR, let’s look at the full context:
This shows that the CV ROR is about half that of the Smallpox vaccine for both myocarditis and pericarditis, is also considerable smaller for myocarditis than Clozapine, and is of similar magnitude to four other drugs for myocarditis and one other drug for pericarditis.
All that this really tells us is that most drugs come with risks.
This is even before we delve into the biases in the data that the authors acknowledge in the text that @sfmatheson quoted.
This means that there is little point in you or ‘trialsitenews’ 
bringing up this study, beyond vacuous and irresponsible scare-mongering.
I therefore support @sfmatheson referral of you for closer moderator scrutiny.
