accine advisers to the US Centers for Disease Control and Prevention say there has been a higher-than-expected number of cases of a heart ailment among young people, most often males, who've recently received their second doses of the Pfizer and Moderna Covid-19 vaccines. The CDC says the reports of the ailment are "rare" and that "most patients who received care responded well to medicine and rest and quickly felt better."
The advisers' statement, posted June 1 on the CDC website, strikes a different note from their statement about two weeks earlier, which said that the rates of myocarditis -- inflammation of the heart muscle -- were not higher among vaccinated people than among unvaccinated people.
The new report comes as the Israeli Ministry of Health finds a "likelihood of a link" between the second dose of the Covid-19 vaccine and myocarditis, most commonly among males ages 16 to 30.
The June 1 report by a work group of the CDC's Advisory Committee on Immunization Practices states that within 30 days of receiving the second dose of either Pfizer or Moderna vaccines, "there was a higher number of observed than expected myocarditis/pericarditis cases in 16-24-year-olds."
