Stacy Fisher+FollowWild Reaction After COVID Booster?A patient with systemic mastocytosis had a delayed but severe mast cell activation (MCA) attack after getting an mRNA COVID booster—think fever, rash, and crazy-high cytokine levels.

Doctors say tracking IL-6 levels could help treat others with SM during these scary episodes. #MedicalMystery #COVID19 #VaccineSideEffects #SystemicMastocytosis #HealthNews #Health173431Share
