Myopericarditis following COVID-19 vaccination: Updates from the Vaccine. Adverse Event Reporting System (VAERS). CDC Aug 30, 2021.

• 2,574 reports of myopericarditis or pericarditis to VAERS (as of August 18, 2021)
  • 1,903 myopericarditis, 671 pericarditis

• Epidemiology of myopericarditis following COVID-19 vaccination similar to previously reported updates
  • Primarily in younger males, after dose 2 mRNA vaccination, symptom onset clustering within several days of vaccination

• Limited follow-up information in VAERS case reports suggests most patients (77%) recovered from symptoms at time of report or follow-up

• Observed vs. Expected analysis with VAERS reports
  • Males: Observed > Expected in age groups through 49 years
  • Females: Observed > Expected in age groups through 29 years

• Enhanced surveillance for myocarditis outcomes after mRNA COVID-19 vaccination in VAERS case reports is ongoing
