It's important to mention that catching COVID also causes myocarditis https://www.cdc.gov/mmwr/volumes/70/wr/mm7035e5.htm Edit: this article says out of 192 405 448 people, 1626 had myocarditis, or about 0.0008%. In contrast, the CDC estimates COVID has a 0.146% chance to give you myocarditis.

It's not one or the other any more, as You can easily catch symptomatic Covid being fully vaccinated, question is; does risk multiply, sum or maybe the vaccine somehow protects against it.

That is not true for every age group.

Number of registered cases of myocarditits after vaccination is not very different from baseline, while covid infection increses risk of miocarditis 16 times.

I wouldn't be surprised if incresed risk of miocarditis after second dose is completely explained by changes in behavior of people who finally got vaccinated after many monthes of lockdowns.

They probably started going out more and exposing themselves to coronavirus which vaccine provides partial protection against.

Researchers don't even exclude from this research people who got full blown covid before their miocarditis.

Great twitter thread on this subject [0]:

"Data out of Israel ... suggests that vaccine-induced myocarditis is caused by the spike protein. In that case, Covid would cause the same condition in the same person -- but more severely, attached to a fully-fledged living virus.

To be clear: whoever gets heart inflammation from Moderna would’ve almost certainly got it worse from Covid. The issue arises from the spike protein itself. That’s why we don’t see myocarditis from non-MRNA vaccines like Astra Zeneca."

I don't have the numbers to answer this but which groups are getting myocarditis also matters. If covid causes myocarditis in 1 out of 100 people in an age group prone to myocarditis, but mRNA causes myocarditis in 15 out of 1000 people in an age group that doesn't get myocarditis, then then we should be very concerned about the mRNA myocarditis and adjust our policies accordingly.

Again, I made up those numbers and I'm not saying mRNA is worse. My point is that we should take a more nuanced and honest view than "they both cause it" or even "X has a great rate; therefore Y is better"

If I'm reading both summaries correctly:

Rates of myocarditis after 2nd shot for males 16 to 17 years of age: 105.9 per million doses of the BNT162b2 vaccine

Rates of myocarditis from COVID-19: 1500 per million cases

I rewrote both stats to be in the form of "x per 1 million" but I don't think that's a fair thing to do. Not everyone is going to get both a vaccine and get covid.

What's a better comparison? Rates of myocarditis for a unvaccinated person (roughly rate of getting covid multiplied by rate of myocarditis if getting covid) versus rates of myocarditis if vaccinated?

stats are hard, explaining stats are even harder. I'm already screwing this up.

I posted a similar comment, but it's not the same - AZ uses a modified non-Covid virus that has been engineered to model the spike protein. I'm not sure why that spike protein is different than the MRNA, other than being attached to a virus.

>In viral vector vaccines (AstraZeneca, Sputnik, Johnson & Johnson) the gene for the spike protein is introduced into an adenovirus. Following vaccination, the modified adenovirus will infect cells of the host, which will subsequently start to produce the spike protein

So if there is a difference in the incidence of myocarditis, it must be for a different reason.

Yes, but how about breakthrough infections as You can easily get symptomatic Covid nowadays especially with Omicron, do You have any data on this?
