Ask-A-Doc: How Do Allergy Shots Work?

Q: I have terrible allergies in the spring and summer and was told allergy shots might provide relief. How do they work?

A: Allergy shots work like a vaccine. Your body responds to injected amounts of a particular allergen (pollen, mold, pet dander, etc.), given in gradually increasing doses, by developing immunity or tolerance to the allergen. The injections help your body stop reacting to your environment, thereby decreasing the allergy symptoms and the need for allergy medications.
