To assess the benefit-risk balance of mRNA vaccines in adolescents and young adults, ACIP reviewed an individual-level assessment that compared the benefits (i.e., COVID-19 infections and severe disease prevented) to the risks (number of cases of myocarditis) of vaccination, using methods similar to those described previously. Specifically, the benefits per million second doses administered (i.e., the benefits of being fully vaccinated in accordance with the FDA EUA) were assessed, including 1) COVID-19 cases prevented based on rates the week of May 29, 2021; 2) COVID-19 hospitalizations prevented based on rates the week of May 22, 2021; and 3) COVID-19 intensive care unit (ICU) admissions and deaths prevented based on the proportion of hospitalized patients who were admitted to the ICU or died. Among 192 405 448 persons receiving a total of 354 100 845 mRNA-based COVID-19 vaccines during the study period, there were 1991 reports of myocarditis to VAERS and 1626 of these reports met the case definition of myocarditis.

Although Rare, New Data Suggests Higher Rate of Myocarditis - BioSpace A histopathologic definition and classification. https://www.cdc.gov/vaccines/covid-19/info-by-product/janssen/risk-benefit-analysis.html. 2 0 obj More information is available, Recommendations for Fully Vaccinated People, Investigating Long-Term Effects of Myocarditis | CDC, Clinical Considerations: Myocarditis after mRNA COVID-19 Vaccines, National Center for Immunization and Respiratory Diseases (NCIRD), Possibility of COVID-19 Illness after Vaccination, Investigating Long-Term Effects of Myocarditis, How and Why CDC Measures Vaccine Effectiveness, Monitoring COVID-19 Cases, Hospitalizations, and Deaths by Vaccination Status, Monitoring COVID-19 Vaccine Effectiveness, U.S. Department of Health & Human Services, In both cases, the bodys immune system causes inflammation in response to an infection or some other trigger. stream An official website of the United States government. in July asked Pfizer-BioNTech and Moderna to enroll more children in their clinical trials in order to detect less common side effects. The EUA fact sheets should be provided before vaccination; in addition, CDC has developed patient and provider education materials about the possibility of myocarditis and symptoms of concern, to ensure prompt recognition and management of myocarditis. Myocarditis Occurring After Immunization With mRNA-Based COVID - JAMA In a population-based cohort study of adolescents and adults in Denmark who received two doses of the same mRNA vaccine against COVID, the risk of myocarditis or myopericarditis within 28 days. Jerome Fleg, M.D., a program officer with the National Heart, Lung, and Blood Institute (NHLBI) Division of Cardiovascular Sciences, oversees and conducts research on heart disease. At the time of this report, 323 of these 484 cases were determined to meet criteria in CDCs case definitions for myocarditis, pericarditis, or myopericarditis by provider interview or medical record review (Table 1).
