COVID-19 Outbreak Information Updates (Reboot) [over 150.000,000 US cases (est.), 6,422,520 US hospitilizations, 1,148,691 US deaths.]

I agree with them. The vaccine doesn’t really prevent transmission only prevents severe illness which just isn’t really a threat. Vaccine does increase myocarditis for male adolescents at a disproportionate rate, particularly shots 2 and 3.

6 months ago it took more risk off the table than it presented.

For people 30+ that is still true.
I don't agree with them. Vaccination does help prevent transmission, since it reduces the risk of being infected in the first place, and if you're not infected, you're not infectious. Additionally, Covid-19 itself has a substantially higher risk of myocarditis, and that also tends to present itself more seriously than the rarer vaccine-associated myocarditis.

So, assuming the risk of exposure to Covid is substantial, then vaccination offers an overall reduction in the risk, and potential severity, of myocarditis. Plus the indications are that it reduces the risk, and severity, of long Covid, etc.
