Here we agree. But already Pfizer gen therapy induced myocarditis is 5x above background according the US military study we here once linked. 500 adverse reaction half with with live long damage among 1 mio gen therapies is way (> 10x) above background.
Yes to 5X myocarditis, but the VIM is very mild (would not normally be diagnosed as such) and nothing like normal myocoarditis, which is serious and can have long-term side effects. And 5X very very small is still very very small.
One thing - background is continuous, and 2nd vaccination is a one-off event, so you need to state over what time you are measuring background for this comparison to be meaningful. VIM occurs within a week of the vaccination since it is essentially a temporary allergic reaction in the heart muscle. It is guaranteed you gte your 5X choosing a suitable period.
No to 250 life-long damage. Only thing I can't tell you without a lot of details is which of the various anti-vax "make the numbers look bigger" tricks that numb er comes from. And given your lack of clearly linked evidence I'm not likley to do so.
For your personal illumination once look into https://www.adrreports.eu/de/search_subst.html# letter "C"
so far 20'000 cardiac disorders in the EU
Sorry - what does the EU prevalence of cardiac disorders have to do with vaccines?
Unless - you are saying every background heart attack in a vaccinated person is caused by the vaccine. That is anti-vax lie #1.
