Figure. Time Courses of Patients With Multisystem Inflammatory Syndrome in Children (MIS-C) Receiving SARS-CoV-2 Vaccination.

Fifteen patients (5 girls and 10 boys, aged 12 to 18 years) with a history of MIS-C were vaccinated against SARS-CoV-2. Most patients received 2 doses, 21 days apart. One patient received the 2 doses 6 months apart, which was suggested as a possible immunization schedule by Italian authorities for patients with a history of COVID-19 in the preceding 12 months. The parents of another patient elected in advance to follow a personalized vaccination strategy with additional time between the 2 doses; this decision was not because of any adverse event. Each row represents a patient. The light blue sections are in proportion to the time from their presentation with MIS-C to their first dose of the BNT162b2 vaccine, and the white sections are in proportion to the time from their last vaccine until submission.
