“Myocarditis (or pericarditis or myopericarditis) from primary COVID19 infection occurred at a rate as high as 450 per million in young males. Young males infected with the virus are up 6 times more likely to develop myocarditis as those who have received the vaccine.” [0]

So there’s a preprint stating that COVID-19 causes myocarditis at a higher rate than via vaccination. So it’s not quite clear to me whether or not, if looking at it from a risk of myocarditis, that not getting vaccinated is the better choice.

And according to the JCVI, it still is marginally beneficial to get vaccinated over not getting vaccinated. So it’s not like they are advising that natural infection is safer than vaccination.

“For otherwise healthy 12 to 15 year old children, their risk of severe COVID-19 disease is small and therefore the potential for benefit from COVID-19 vaccination is also small. The JCVI’s view is that overall, the health benefits from COVID-19 vaccination to healthy children aged 12 to 15 years are marginally greater than the potential harms.” [1]
