That is factually incorrect. However the point you are making is that parents of young male teens should understand the risks of myocarditis from viruses and vaccines and I agree with that.But you are generalising across the entire population. It is accepted that in younger cohorts the risk of vaccine-induced myocarditis and pericarditis is greater and more serious than that occurring through natural infection.
1. The risk of mycarditis from a young teen getting vaccinated are tiny but they are higher than the general population.
2. The risk of a young male teen getting myocarditis from contracting covid are tiny but they are higher then the general population, and higher than the risk for the same age cohort getting myocarditis from the vaccine.
3. The risk of contracting covid for a young male teen is lower than the general population but not as low as the risk of a vaccinated young male teen.
All of this has to be balanced by the parents advised by their primary physician, and hopefully not advised by blogs and forums on the internet.
