US detects unusual heart problems in young people and adolescents vaccinated against coronavirus

Very rare cases of heart problems in adolescents and young adults vaccinated against coronavirus were reported this week by the health authorities of USA, without a link to vaccination being established for the time being.

Cases of myocarditis, an inflammation of the heart muscle, occurred in people who received a messenger RNA vaccine such as those developed by Pfizer / BioNTech or Moderna, reported the Centers for Disease Control and Prevention (CDC) in the United States.

Most of the cases “appear to be benign”, explained and ensured that the situation is being monitored.

“Relatively few” cases have been reported, according to CDC, which did not specify the names or the exact ages of the people affected.

The episodes occurred mainly in “adolescents and young adults”, in the four days following the injection.

These myocarditis, which occurred more frequently “after the second dose,” have affected men more than women.

The number of myocarditis reported does not currently exceed the normal rate of this condition in people of this age group, according to health authorities.

At the end of April, five cases of myocarditis were detected in France in people who had received the Pfizer / BioNTech anticovid vaccine but a link with the injections has not been shown.

In the United States, the authorization for the use of the Pfizer / BioNTech vaccine was extended to adolescents between 12 and 15 years old on May 10.
