The Food and Drug Administration (FDA) and the US Centers for Disease Control and Prevention (CDC) are investigating reports that vaccination with Moderna may be associated with a higher risk of myocarditis in young people than previously thought. This is reported by The Washigton Post, citing representatives of two agencies.
In June, the FDA medical regulator issued a warning about an increased risk of myocarditis – inflammation of the heart muscle – in adolescents and young adults when vaccinated with Pfizer and Moderna. The current investigation is prompted by evidence from Canadian authorities that receiving the Moderna vaccine carries an even greater risk, especially for people under the age of 30. The risk for those vaccinated with this drug can be up to 2.5 times higher than for those vaccinated with Pfizer, the newspaper said, citing sources. Moderna declined to comment on the situation.
The interlocutors of the publication warn that it is too early to draw any conclusions; currently, similar data on the US population are just beginning to be collected. In addition, CDC experts emphasize that the risk of heart inflammation with COVID-19 is much higher than when receiving vaccines against infection.
