May 22 (Reuters) – Some teens and young adults who have received COVID-19 vaccines have suffered heart inflammation, a US Centers for Disease Control and Prevention advisory group said, recommending further study of the rare disease.

The CDC’s Advisory Committee on Immunization Practices in a statement dated May 17 said it had considered reports that a few young people vaccinated, mostly adolescents and young adults, and mostly men, had developed myocarditis. , inflammation of the heart muscle.

The disease often goes away without complications and can be caused by a variety of viruses, the CDC group said.

CDC’s surveillance systems had not found more cases in the population than expected, but members of the immunization committee said healthcare providers should be made aware of reports of the “potential adverse event.” , the committee said in the statement.

He did not say how many people had been affected and recommended further investigation.

The CDC said cases typically occur within four days of receiving mRNA vaccines. He did not specify which vaccines. The United States has given emergency clearance for two mRNA vaccines, from Moderna Inc and Pfizer / BioNTech.

In April, Israel’s health ministry said it was examining a small number of cases of heart inflammation in people who received Pfizer’s vaccine, although it has yet to draw any conclusions. Most cases in Israel have been reported in people up to the age of 30.

Pfizer at the time said it had not observed a higher rate of disease than would normally be the case in the general population and that a causal link to the vaccine had not been established.

Pfizer and Moderna did not immediately respond to requests for comment on Saturday.

The CDC in late April, after news of the Israeli investigation, said it saw no connection between the two.

Earlier this month, U.S. regulators extended approval for Pfizer and BioNTech’s COVID-19 vaccine to children aged 12 to 15.
