A higher-than-usual number of cases of a type of heart inflammation has been reported following Covid-19 vaccination, especially among young men following their second dose of an mRNA vaccine, the Centers for Disease Control and Prevention said Thursday.
Overall, 226 cases of myocarditis or pericarditis after vaccination in people younger than age 30 have been confirmed, Dr.
Teenagers and people in their early 20s accounted for more than half of the myocarditis cases reported to the CDC's safety monitoring systems following Covid-19 vaccination, despite representing a fraction of people who have received the shots.
The vast majority of the cases were sent home following a visit to a hospital as of the end of May.
The CDC had information on the recovery of patients in 220 cases; in more than 80 percent of these cases, patients got better on their own.
Despite the increased number of reported myocarditis cases among young people, Shimabukuro said, no major red flags have been identified
The CDC will hold a meeting of its Advisory Committee on Immunization Practices on June 18 to further look at the evidence and assess the risk of myocarditis following vaccination
