Multisystem Inflammatory Syndrome in a 12-Year-old Boy After mRNA-SARS-CoV-2 Vaccination.

Multisystem inflammatory syndrome in children (MIS-C) following SARS-CoV-2 infection is well known. We describe a 12-year-old child developing MIS-C after receiving 2 doses of mRNA COVID-19 vaccines without clinical evidence of COVID-19 infection. A possible association between the SARS-CoV-2 vaccine and MIS-C cannot be excluded.
