In a study reported yesterday in JAMA Internal Medicine, children and adolescents previously diagnosed with multisystem inflammatory syndrome (MIS-C) reported no serious complications after COVID-19 vaccination. Almost all participants received the Pfizer COVID-19 vaccine. The Centers for Disease Control and Prevention recommends COVID-19 vaccination for patients with a history of MIS-C, a rare and potentially fatal immune reaction to SARS-CoV-2 infection. According to CDC data, over 9,000 U.S. patients have been diagnosed with MIS-C, which appears to be on the decline.
“A big part of that decline is that COVID vaccination has been protective against this rare condition in those who have received it,” said Audrey Dionne, M.D., a pediatric cardiologist at Boston Children’s Hospital who served as co-leader for the study, funded by the National Institutes of Health.
