Increased cases of myocarditis and pericarditis have been reported in the United States after mRNA COVID-19 vaccination (Pfizer-BioNTech and Moderna) since April 2021, particularly in adolescents and young adults. These rates for ages 16-24 following a second dose are above what is expected. Myocarditis or pericarditis has now been verified in 226 people ages 30 and younger who have received an mRNA COVID-19 vaccine and Federal Health Officials are investigating reports of approximately 250 more cases.
Due to this increase, the Advisory Committee on Immunization Practices (ACIP) is scheduled to hold an emergency meeting on June 18, 2021 to discuss myocarditis cases and the American Academy of Pediatrics (AAP) plans to closely monitor meeting. However, at this time, there is no recommended change to vaccination of adolescents 12 and older.
Cases have been reported predominantly in young males 16 years of age and older, with onset of symptoms typically manifesting within several days after mRNA COVID-19 vaccination. Symptoms have more often occurred after the second dose of vaccine than the first dose.
It is recommended by the CDC that clinicians consider myocarditis and pericarditis in patients who develop acute chest pain, shortness of breath or heart palpitations within a week after vaccination, and to report cases of myocarditis and/or pericarditis after COVID-19 vaccination to the Vaccine Adverse Event Reporting System. (VAERS).
