Risk of myocarditis from the virus is higher than the risk of myocarditis from the vaccine. https://www.cdc.gov/mmwr/volumes/70/wr/mm7035e5.htm https://www.cdc.gov/mmwr/volumes/70/wr/mm7035e5.htm And your odds of knowing 2 kids / young adults who both got myocarditis reactions to the vaccine are roughly 1-in-500 if you know 50 people who got the vaccine to the point you would have heard about them getting myocarditis. That isn't winning-the-lottery odds. It also isn't clear that boosters will be required (the title study is not terribly good and is full of confounding issues), particularly since the older age groups that really need boosters don't overlap with the younger age groups that have the higher rate of myocarditis as a side effect. We also have no data on the side effects of boosters in those younger age groups and if they produce myocarditis at the same rate as the initial dose. We also don't even have any information on immunological waning of boosters and there's reason to believe that immunity after boosting will be considerably more durable. Some virologists are of the opinion that it always should have been a 3 shot series with a booster after 6 months and then you're done--but we're in the process of discovering the right dosing schedule on the fly.
