Adolescent Myocarditis After COVID-19 Vaccination Is Rare

JAMA. 2021;326(10):902. doi:10.1001/jama.2021.14237

Postmarketing safety monitoring data suggest that nonserious local and systemic reactions are common among adolescents who receive a SARS-CoV-2 mRNA vaccine, while reports of severe adverse events like myocarditis are rare.

Between December 2020 and mid-July of this year, nearly 9 million US adolescents aged 12 to 17 years received Pfizer-BioNTech’s COVID-19 vaccine, the only one approved for use among this age group. During that period, the CDC’s Vaccine Adverse Event Reporting System (VAERS) collected 9246 reports of postvaccination adverse events in this age group, or 1 per 1000 recipients.

    Injection Site
    Robert Raines, MD. | Teaching Hospital
    The photo appears to show an injection being given mid arm, clearly not in the deltoid which is, I believe, the preferred site. The shot pictured may or may not have reached the triceps or may well have been given subcutaneously. It does raise the question in all studies as to how much injection site affects the vaccine’s effectiveness (and of course, side effects). Many people who are not used to giving shots are giving them around the world.
