Looks like the Israelis are the first to start making a link with Myocarditis and the Pfizer vaccine, especially in young men.
"The COVID-19 vaccine made by Pfizer and BioNTech appears to put young men at elevated risk of developing a heart muscle inflammation called myocarditis, researchers in Israel say. In a report submitted today to the Israeli Ministry of Health, they conclude that between one in 3000 and one in 6000 men ages 16 to 24 who received the vaccine developed the rare condition
But the rate of myocarditis following vaccination among young men was higher. Ninety percent of the cases picked up in Israel appeared in men, and although myocarditis is normally more common among young men, the rate among those vaccinated was somewhere between five and 25 times the background rate, the report says"

This then begs the question on vaccinating children, In Amerca a preprint by reputable doctors estimates the rate of a cardiac adverse event after a second dose of the vaccine in boys aged 12-15 at 1 in 6200. t.co/bZBecW0nXi?amp=1
Vinjay Prasad is advocating for giving just one vaccine dose to children. Now I know the usual conformists will jump in and say myocarditis is mild and resolves it self, and the younger the better for the vax to save us from covid.
"~95% of US children with vaccine-induced mycarditis get hospitalized."

In the end hopefully rational people will make the correct decision between potential vaccine harm vs the harm caused by covid in children.
