Some teenagers and young adults who received the Covid vaccine experienced heart inflammation, said an advisory group at the US Centers for Disease Control and Prevention, recommending further studies of rare conditions.
The CDC Immunization Advisory Board investigated reports of a small number of young vaccinated individuals (mainly men, adolescents and young adults) developing myocarditis (inflammation of the myocardium) in a statement dated May 17. Said.
According to the CDC group, the condition often subsides without complications and can be caused by a variety of viruses.
The CDC surveillance system did not find more cases than expected in the population, but members of the vaccination committee should be aware of reports of “potential adverse events” to health care providers. The committee said it felt.
He did not state how many people were affected and recommended further investigation.
Dr. Ameshua Darja, a senior scholar at the Johns Hopkins Center for Health and Security, said vaccines are known to cause myocarditis and it is important to monitor for a causal link to the vaccine. .. It is important to look at the risk-benefit ratio, he said. “Vaccines, even if they are decisively established, will obviously be far more beneficial by overcoming this very low risk.”
According to the CDC, these cases usually occurred within 4 days of receiving the mRNA vaccine. Which vaccine has not been identified. The United States has granted urgent permission to two mRNA vaccines, Moderna and Pfizer / BioNTech.
The Israeli Ministry of Health said in April that it was investigating a small number of cases of heart inflammation in people vaccinated with Pfizer, but no conclusions have yet been reached. Most cases in Israel have been reported among people up to the age of 30.
Pfizer at the time said no higher-than-normal rates were observed in the general population and no causal link to the vaccine was established.
Pfizer and Moderna did not immediately respond to requests for comment on Saturday.
After news of the Israeli investigation, the CDC in late April said there was no link between the two.
Earlier this month, US regulators extended Pfizer and BioNTech vaccine approvals to children aged 12 to 15.
