The CDC will hold an “emergency meeting” of its advisers June 18 to discuss rare but more frequent than expected reports of heart inflammation after Pfizer and Moderna mRNA-based doses. So far, CDC physicians have identified 226 reports that may meet the “working case definition” of myocarditis and pericarditis after injections of these vaccines. The vast majority of the patients have recovered, but 41 patients continue to have symptoms, 15 are still hospitalized, and 3 are in the ICU.
Nearly 130 million Americans who were fully vaccinated with doses of Pfizer or Moderna. Complications in the form of rare inflammation are a paltry number, but doctors still want to get a better picture of what is going on.
