Pirquet called this occurrence “allergy” from the Greek words allows meaning “other” and ergon meaning “work”. Previously, all shapes of reaction were categorized as allergies, and all were thought to be sourced by a rude commencement of the resistant system. Later, it turned out to be clear that more than a few different disease mechanisms were concerned, with an ordinary link to a messy activation of the resistant system. In 1963, a new categorization scheme was designed by Philip Gell and Robin Coombs that explained four types of sensitivity reactions, known as Type I to Type IV reaction. With this new categorization, the word “allergy” was limited to only type I hypersensitivities (also called instant reaction), which are distinguished as fast developing reactions.
