Before administering vaccines allergy testing is needed to determine which allergens will trigger allergic reactions. These studies include skin or patch tests and a blood test called “radioallergosorbent test” or RAST. The results are not always accurate. You may get a positive test without allergic symptoms or, conversely, to show allergy symptoms even with a negative test.

How it is done

When given an allergy vaccine is injected a small amount of allergen under the skin, usually in the fleshy part of the forearm. At the start of treatment, the injections are usually once a week and go increasing doses of allergens gradually with each injection.
