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