Yes, and people like Bret Weinstein say this is a massive problem and why there’s heart inflammation, if the mrna enters heart muscle your immune system might well attack it, the problem is - heart muscle does not get remade.
The problem with this is that there's simpler explanations. Myocarditis is more frequent with C19 infection than vaccination, so it seems spike protein circulating is "enough".
Also this study didn't find significant uptake of mRNA in the heart (though it did find notable uptake in the lungs).
The Mycocarditis line is not true - it highly depends on gender and age. Repeating that its more frequent for infection outright is wrong, it is only in certain sub-populations (female, older).
Moderna does seem to have an effect in the direction you name; the Pfizer vaccine seems to have a lower risk than infection in all categories. Overall, the myocarditis risk is lower with vaccination than infection with both Moderna and Pfizer, but it may not be in some subpopulations with Moderna.
It’s such a dumb topic too - because when you focus solely on the myocarditis risk stratification between Covid and the vaccine, you lose sight of all of the other morbidities that come with Covid. It’s like that video making the rounds right now where Bill Maher is trumpeting that the infection provides as strong protection against severe disease compared to the vaccine. Cool! Not actually surprising but kind of misses the obvious point that it involves you getting Covid, a serious, highly
transmissible disease, when you could get the same protection without the illness.. I guess you could use the evidence to adjust guidance on vaccine schedule but protection still wanes over time so..
Finland, Denmark and Sweden recommend against getting vaccination for young men as they have almost no risk with Covid outside of extreme co-morbidities.
They didn't actually do that - and you should change your media diet if you sincerely believe that they did.
Denmark is probably the most stark -- after they had >80% uptake in their initial vaccination drive and then Omicron proved to be less dangerous, they no longer recommend boosters for under 50s unless you have risk factors.
Sweden still recommends 3 doses for everyone over the age of 18 (https://www.krisinformation.se/en/hazards-and-risks/disaster....) They no longer recommend that all children receive the vaccine but that's a much more neutral stance than "recommend against getting it".
I think the data still supports what I said, even in that article, but also if you want to be really accurate you'd need a meta review of a variety of articles I've read now in detail, and my general intuition is its clear that < ~30yr old men are higher risk.
Also this study didn't find significant uptake of mRNA in the heart (though it did find notable uptake in the lungs).
