In medicine, anaphylaxis is a severe and rapid multi-system allergic reaction. Anaphylaxis occurs when a person is exposed to a trigger substance, called an allergen. Minute amounts of allergens may cause a life-threatening anaphylactic reaction. Anaphylaxis may occur after ingestion, inhalation, skin contact or injection of an allergen. Vaccines contain a number of triggering allergens, including, gelatin, latex, animal proteins and other toxic substances.

The most severe type of anaphylaxis—anaphylactic shock—will usually lead to death in minutes if left untreated.

The word is from New Latin (derived from Greek ana, meaning “up, again, back, against”) + phylaxis, meaning “guarding, protection”).
