PIMS, paediatric inflammatory multisystem syndrome, is severe inflammation in the body following infection with the coronavirus. It occurs in rare cases in children and adolescents, mostly three to four weeks after a coronavirus infection.
It is unclear what causes the condition to develop. There are currently also no reliable data on its frequency. Most young patients who are affected have to be admitted to hospital, with around half requiring intensive care. Doctors are gaining a better and better understanding of what was initially a new syndrome. It is now readily treatable. Around 150 cases are known in Switzerland to date. No one has died of PIMS in this country.
It can be assumed that vaccination also protects people from the consequences of coronavirus infection, including PIMS. New data for 12- to 15-year-olds indicate that the mRNA vaccines provide effective protection against PIMS.
