6/18/21- Potential Myocarditis and/or Pericarditis Following COVID-19 Vaccinations Remain Rare

On 5/26/21, we sent a health alert about potential myocarditis and/or pericarditis following mRNA COVID-19 vaccinations.  These events remain rare and COVID-19 vaccination continues to be recommended as an overall safe and effective measure to protect individuals and prevent transmission of SARS-CoV-2, including the current circulating variants.

DOH has provided an update on the status of their work with the CDC on case investigations in Washington State, which is found here: WA_DOH_Myocarditis_Pericarditis_Reporting_06.11.2021.

In addition, FAIR Health has posted a White Paper, a study of claims for post-acute COVID-19 events, including cardiac inflammation, which provides an indirect comparison of the relative risk of potential post-vaccine cardiac inflammation to the risk from COVID-19 itself.

The CDC provided an update on COVID-19 safety to the FDA Vaccines and Related Biological Products Advisory Committee on 6/10/21 which included a review of data to that date on myocarditis and pericarditis following mRNA COVID-19 vaccination.

Please continue to report events associated chronologically to COVID-19 vaccination to VAERS, whether or not you think there is a causal relationship.

  • Consider a diagnosis of myocarditis or pericarditis in any evaluation of chest pain following COVID-19 vaccination
  • Inquire about recent COVID-19 vaccination in any patient presenting with symptoms consistent with myocarditis or pericarditis (chest pain or pressure, or shortness of breath, EKG abnormalities); and
  • Report such cases promptly to the U.S. Vaccine Adverse Events Reporting System (VAERS: https://vaers.hhs.gov/reportevent.html).
