On Thursday, the CDC said that an Emergency Meeting of its experts would be held on June 18th to investigate uncommonly. However, higher-than-expected reports of heart inflammation following doses of the mRNA-based Pfizer and Moderna COVID-19 vaccines. According to the CDC, 226 reports have been documented that may satisfy the agency’s working case definition of myocarditis and pericarditis due to the injection.
Although most patients have healed, 41 have persistent symptoms, 15 are still hospitalized, and three are in intensive care. The reports represent a small portion of the over 130 million Americans who have received complete vaccinations from either Pfizer or Moderna. Shimabukuro said their findings were mainly “compatible” with reports of rare occurrences of heart inflammation researched in Israel and released earlier this year by the US Department of Defense.
The new information on myocarditis and pericarditis was first presented to a group of independent advisers for the Food and Drug Administration on Thursday. They are gathering to examine how the agency should approach emergency use authorization for COVID-19 vaccinations in younger children. Pfizer revealed this week that it has settled on dosages to use in a clinical study in children as young as six months old and aimed to submit data by October after receiving an emergency use authorization for its COVID-19 vaccine in Americans as young as 12 last month.
