Health agency says the rates of myocarditis are not higher than expected and no causal link has been found to mRNA jabs.
Some teenagers and young adults who received Covid-19 vaccines have experienced heart inflammation, a US Centers for Disease Control and Prevention advisory group said, recommending further study of the rare condition.
In a statement dated 17 May, the CDC’s advisory committee on immunisation practices said it had looked into reports that a few young vaccine recipients, predominantly male adolescents and young adults, developed myocarditis, an inflammation of the heart muscle.
The condition often goes away without complications and can be caused by a variety of viruses, the CDC group said.
CDC monitoring systems had not found more cases than would be expected in the population, but members of the committee on vaccinations felt that healthcare providers should be made aware of the reports of the “potential adverse event”, the committee said in the statement.
It did not say how many people had been affected and recommended further investigation.
Dr Amesh Adalja, senior scholar at the Johns Hopkins Center for Health Security, said vaccines are known to cause myocarditis and would be important to monitor to see if it was causally related to the vaccine.
It is important to look at the risk-benefit ratio, he added. “Vaccines are going to unequivocally be much more beneficial outweighing this very low, if conclusively established, risk.”
The CDC said the cases typically occurred within four days after receiving mRNA vaccines. It did not specify which vaccines. The US has given emergency authorisation to two mRNA vaccines, from Moderna Inc and Pfizer/BioNTech.
Israel’s health ministry in April said it was examining a small number of cases of heart inflammation in people who had received Pfizer’s vaccine, though it had not yet drawn any conclusions. Most of the cases in Israel were reported among people up to age 30.
Pfizer at the time said it had not observed a higher rate of the condition 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…
