Autoimmune inflammatory reaction after vaccination is a rare clinical entity. Reactive arthritis has been described after various vaccinations, but not after mpox vaccination. Here we present a case of recently diagnosed reactive arthritis after mpox vaccination that presented in the context of unrelenting fever and diarrhea complicated by migratory arthritis and anterior uveitis. We have reported this case to the Vaccine Adverse Event Reporting System (VAERS).
