Allergies are over-reactions of the immune system in certain individuals to seemingly and generally harmless foreign proteins and substances. Allergies usually do not occur at the first exposure. When a person is exposed to an allergen for the first time, the body develops molecules called antibodies against the typd proteins. This is called an alergy response.
