United States: The US Food and Drug Administration (FDA) has now announced that, according to recent data from the CDC, those who had COVID-19 vaccinations from 2020 through 2022 may have had a higher risk of myocarditis.
More about the news
Even so, the CDC pointed out that no extra risk has been found in those who got shots in later years.
Before, the labels on those vaccines cautioned that a heart condition called myocarditis and pericarditis inflammation could occur, and the US Centers for Disease Control and Prevention (CDC) says both are rare but can happen after vaccination.
The warning will now cover children and teens in certain age brackets. Multiple studies demonstrate that the mRNA Covid-19 vaccines are both safe and effective, and many people have received them without having major problems, CNN Health reported.

FDA orders new WARNING LABELS on COVID vaccines.
Why? Heart inflammation risks in young men may LAST MONTHS…NOT DAYS.
Myocarditis, Pericarditis, 8 cases per million doses…Pfizer & Moderna must now disclose it.

Some research suggests that contracting COVID-19 raises the risk of myocarditis or pericarditis more than being vaccinated does.
The CDC told its vaccine panel last month that research suggested myocarditis was more common after vaccination from 2020 to 2022.
Acute myocarditis, which occurs only rarely after vaccination, usually subsides swiftly. The advisers were informed by the CDC.
Before, the vaccines were labeled to show the highest risk of heart problems was for men between 18 and 24 for Moderna and 12 and 17 for Pfizer; the new warnings for both vaccines are for males between 16 and 25, CNN Health reported.
