CDC data showed 196 reports of myocarditis and pericarditis among 18- to 24-year-olds through May 31, compared with an expected rate of between eight and 83 cases.

Among 16- to 17-year-olds, 79 cases of myocarditis and pericarditis were reported through May 31. The expected rate among people in this age group is between two and 19 cases, Shimabukuro said during his presentation.

Shimabukuro said the CDC’s findings were “mostly consistent” with reports of rare cases of heart inflammation that had been studied in Israel and reported by the U.S. Department of Defense earlier this year.

Children’s Health Defense asks anyone who has experienced an adverse reaction, to any vaccine, to file a report following these three steps.
