According to data from two safety monitoring systems, there has been a higher than expected number of young men experiencing heart inflammation after their second dose of the mRNA COVID-19 vaccine from Pfizer/BioNTech and Moderna. The information was released by the CDC on Thursday.
After Israel’s Health Ministry had reported that their was a potential link between the Pfizer COVID vaccine and and the heart inflammation in young men the CDC began to investigate cases where there have been similar reports. However the CDC is not confirming if there is a definite link between the vaccine and cases of myocarditis or pericarditis. The CDC has also stated that most individuals have recovered and only a few required hospitalization.
Over 50 percent of the cases reported to the U.S. Vaccine Adverse Event Reporting System after receiving their second dose of the Pfizer/BioNTech or Moderna vaccine were between the ages of 12-24. That age group only accounted for 9 percent of doses administered. A majority of the cases reported occurred within a week of receiving the second dose.
283 cases were reported between the ages of 16-24 while the expectation was that there would only have been between 10-102 cases reported.
