Myocardial Injury After Covid-19 mRNA Booster Vaccination (opens in new tab)

> No patient had ECG- changes, and none developed major adverse cardiac events within 30 days.

Which aligns with

> We found that across this large dataset, the entire COVID-19-vaccinated population of England during an important 12-month period of the pandemic when the COVID-19 vaccines first became available, the risk of myocarditis following COVID-19 vaccination was quite small compared to the risk of myocarditis after COVID-19 infection.

COVID-19 mRNA-1273 is the Moderna vaccine, which was not recommended for youth under 30 in Europe due to potential myocardial injury.

Seems like the conclusion remains that the vaccine causes myocarditis for some small percentage of people and that both the percentage of people and the severity remains less than the risk of myocarditis from COVID itself. As an individual the only behavioral change I might take away from this is even if I am non-symptomatic post vaccination that I should minimize strenuous activity.

Strange that this study showed it was so heavily gendered towards women, while most of the others have shown it in men.
