Immediate hypersensitivity is caused when someone comes in contact with an allergen, such as a food, pollen, or the venom of an insect. In response, the individual generates large amounts of IgE, causing mast cells in tissues and basophils in the blood to trigger a massive amount of histamine that floods the bloodstream.
