COVID-19 vaccines are unlikely to trigger a rare inflammatory condition linked to coronavirus infection in children, according to an analysis of U.S. government data published Tuesday.
The condition, formally known as multisystem inflammatory syndrome in children, involves fever plus symptoms affecting at least two organs and often includes stomach pain, skin rash or bloodshot eyes. It's a rare complication in kids who have had COVID-19, and very rarely affects adults. The condition often leads to hospitalization, but most patients recover.
First reported in the United Kingdom in early 2020, it is sometimes mistaken for Kawasaki disease, which can cause swelling and heart problems. Since February 2020, more than 6,800 cases have been reported in the U.S., according to the Centers for Disease Control and Prevention.
As part of COVID-19 vaccine safety monitoring, the CDC and U.S. Food and Drug Administration added the condition to a list of several potential adverse events of special interest. A few cases reported in people with no detectable evidence of coronavirus infection prompted researchers at the CDC and elsewhere to undertake the new analysis, which was published Tuesday in The Lancet Child & Adolescent Health.
