Allergen Immunotherapy or “Allergy Shots” is an effective vaccination program that increases immunity to allergens that trigger allergy symptoms. Immunotherapy involves administering gradually increasing amounts of an allergen to a patient over several months. The injections are first given on a weekly or bi-weekly basis, and when the maintenance level is reached, eventually on a monthly basis.
This process reduces symptoms that are triggered by allergen exposure. This form of treatment is the closest thing to a “cure” for allergic symptoms.
