During a Jan. 7 interview with members of the Internal Medicine Residency program at Washington University in St. Louis, Fauci admitted that there is a chance of people developing side effects from the vaccine, but underscored the fact that severe allergic reactions are extremely rare. “There have been 21 cases of severe allergic reactions, which brings it to an incidence of about 1 every million…almost invariably in people with a history of severe allergic reactions,” Fauci explained. “So yes, there is an adverse event, but it is easily manageable.” And if you’re worried you may have been exposed, If This Part of Your Body Hurts, You Could Have COVID.
