The event occurred 2 days after a first dose of mRNA-1273 vaccine was administered. The rechallenge was not applicable since only information of one dose was disclosed. Medical history of asthma, several medication allergies, anaphylactic shock and hives remains as confounders. Patient experienced hives, itching, angioedema, swelling of upper airway and tingling; medical intervention was required. Patient received antihistamines and steroids.
