It should also be pointed out that the original article implies that warning labels on the vaccines did not "disclose the very real risks of heart damage that [the vaccines] cause, particularly among adolescent boys and young men."
However, the warning label for Pfizer's vaccine (Comirnaty) specifies that the risk of myocarditis and pericarditis is highest in males 12 through 17 years of age, while the label on Moderna's vaccine (Spikevax) states that males between the ages of 18 and 24 face the highest risk.
The new FDA instructions require warnings on both vaccines to state that the risk is highest for males aged 16 to 25. Therefore, the risk to adolescent males was already stated on the warning labels, with the "expanded" warnings partly serving to bring uniformity in the age range based on recent studies.
