Multisystem inflammatory syndrome in a male adolescent after his second Pfizer-BioNTech COVID-19 vaccine: a report from Turkey

Abstract

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), continues to spread rapidly through human populations, presenting across a continuum of severity from a symptomatic carriage to multi-organ failure and death. Multisystem inflammatory syndrome in children (MIS-C) is a new phenomenon reported worldwide with temporal association with SARS-CoV-2. Multisystem inflammatory syndrome in children is a complication of the SARS-CoV-2 infection, while myocarditis is a rare adverse effect to messenger ribonucleic acid (mRNA) SARS-CoV-2 vaccines, especially in males aged 12–17 years . On the other hand, postimmunization myocarditis is a known rare adverse event after other vaccinations, such as smallpox . Today, rare cases of MIS-C and myocarditis after mRNA SARS-CoV-2 vaccinations have been reported in children or adolescents . We present details on a 15-year-old previously healthy Turkish male adolescent who fulfilled the diagnostic criteria for MIS-C after the Pfizer-BioNTech vaccine.
