Myocarditis typically occurs more commonly in males than in females, and incidence is highest among infants, adolescents, and young adults (1,2). Design, setting, and participants: You may have seen the recent reports linking rare cases. Myocarditis typically causes shortness of breath and chest pain. The benefits (prevention of COVID-19 disease and associated hospitalizations, ICU admissions, and deaths) outweighed the risks (expected myocarditis cases after vaccination) in all populations for which vaccination has been recommended. Among individuals older than 40 years of age, there were no more than 8 reports of myocarditis for any individual age after receiving either vaccine.

Using the Dallas criteria (Aretz HT, Billingham ME, Edwards WD, et al. Within the Vaccine Adverse Event Reporting System (VAERS) (4), the national vaccine safety passive monitoring system, 1,226 reports of myocarditis after mRNA vaccination were received during December 29, 2020June 11, 2021. The FDA - which generally follows the recommendations of its advisers but is not obligated to do so - is likely to authorize the Moderna vaccine for ages 6-17 soon. Heart inflammation, or myocarditis, has been reported as a very rare side effect of COVID-19 vaccines. However, the balance of benefits and risks varied by age and sex because cases of myocarditis were primarily identified among males aged <30 years, and the risks of poor outcomes related to COVID-19 increase with age. and transmitted securely. This risk should be considered in the context of the benefits of COVID-19 vaccination. Canadian public health authorities also found that the rate of myocarditis was higher for both Moderna. Su, J. R., McNeil, M. M., Welsh, K. J., Marquez, P. L., Ng, C., Yan, M., & Cano, M. V. (2021). Crude reporting rates were calculated across age and sex strata. Most of the suspected myocarditis cases in that study developed after the second dose and were among males between 12 and 39 years old. 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.
