This depends a lot on the probability of contracting Covid at all. Roughly speaking, if there's a 1% chance to contract the disease, the vaccine has to be at least 100 times safer. As the chance to catch Covid decreases over time, the risks associated with vaccines become more of a problem.

This is a big assumption. It could also be that it becomes part of the virus background infections we all deal with except that it is high risk if you get it the first time.

When looking that the risk of an non vaccinated individual catching Covid today keep in mind that a lot of people have been vaccinated and the incidence numbers de-facto refer to incidences of the non vaccinated part of the population which would justify a smaller denominator than used (whole population).

Without vaccines the risk of catching covid is of around 70% at least.

Is that for an individual not taking the vaccine but benefiting from herd immunity of others, or a person in a while society without vaccines?

For society in general.

That said, there is no guarantee that herd immunity will ever be reached at least in the US. If herd immunity isn't reached then it's basically guaranteed you'll get it eventually as the disease becomes a "background disease".

Per the article. The age group of concern "accounted for less than 9% of doses administered."

Also, underreporting is a factor - not everyone knows about VAERS, not everyone goes to the Dr. for chest pain etc.

I agree it's favorable, but it's important to understand the effects of any medicine on subgroups of a treatment population.

Have to really consider if the 200 are but a fraction of the actual though. I mean how many are going to be reported?

I'd wager it's approximately the same fraction of myocarditis cases that are reported in the unvaccinated group. There may even be a bias toward over-reporting myocarditis in the wake of a vaccine, as people are primed to look for side effects.
