Q: What are allergy vaccines, and how do they work? A: Allergy medications are very helpful in controlling symptoms but do not cure allergies. As you know, the allergic individual has high IgE for the allergens to which they are allergic. When the allergic individual is exposed to these allergens, their body triggers an overactive immune response. In the process of allergy vaccination, also known as immunotherapy, the allergens are given to the patient, starting at a tolerable dose and gradually given more and more over a period of time. In doing so, the allergic individual’s body starts developing tolerance to these allergens and stops overreacting. It reduces inflammation. This in turn spells relief. The need for medication lessens, and many patients can live normally without having allergy symptoms. The most common and widely practiced method is called subcutaneous immunotherapy. The oral or sublingual immunotherapy is beginning to get attention. Allergen immunotherapy is the only thing that brings you close to cure for allergies.
