A CDC safety group said there’s a “likely association” between a rare heart inflammatory condition in adolescents and young adults mostly after they’ve received their second Covid-19 vaccine shot, citing the most recent data available.

There have been more than 1,200 cases of a myocarditis or pericarditis in 16- to-24-year-olds who received Pfizer’s or Moderna’s Covid-19 vaccine, according to a series of slide presentations published Wednesday for a meeting of the CDC’s Advisory Committee on Immunization Practices.

Myocarditis is the inflammation of the heart muscle, while pericarditis is the inflammation of the membrane surrounding the heart.

“Clinical presentation of myocarditis cases following vaccination has been distinct, occurring most often within one week after dose 2, with chest pain as the most common presentation,” one of the presentations said. CDC officials are gathering more data to fully understand the potential risks, how to manage it and whether there are any long-term issues.

The agency said there have been 267 cases of myocarditis or pericarditis reported after receiving one dose of the mRNA vaccines and 827 reported cases after two doses through June 11. There are 132 additional cases where the number of doses received is unknown, the CDC said.

Roughly 300 million of the shots had been administered as of June 11, the CDC said.

Men under 30 make up the bulk of the cases, the CDC said, and most cases appear to be mild. Of the 295 people who have developed the condition and have been discharged, 79% of them have fully recovered, according to the presentation. Nine people were hospitalized, with two in intensive care as of June 11, according to the CDC.

The CDC is coordinating its investigation with the Food and Drug Administration, which last month authorized the Pfizer-BioNTech vaccine for adolescents ages 12 to 15. Symptoms, which include chest pain and shortness of breath, typically develop within a few days of receiving the shot, the agency has said.
