Abstract
M ultisystem infl ammatory syndrome (MIS) is a serious complication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection that affects multiple body systems (cardiovascular, gastrointestinal, skin). It occurs predominantly in children (MIS-C) (1) and only rarely in adults (MIS-A) (2). The Brighton Collaboration Network (https:// brightoncollaboration.us) includes MIS-C and MIS-A as possible coronavirus disease (COVID-19) vaccination-related adverse events (3). Most MIS cases occur in persons previously or concurrently infected with SARS-CoV-2 (4-6). We report a case of MIS-A that occurred after vaccination of a patient with no evidence of prior SARS-CoV-2 infection.
