Hyposensitization (or allergy desensitization) is a form of
immunotherapy where the patient is gradually
vaccinated against progressively larger doses of the
allergen in question. This can either reduce the severity or eliminate
hypersensitivity altogether. It relies on the progressive skewing of
IgG ("the blocking antibody") production, as opposed to the excessive
IgE production seen in hypersensitivity type I cases.
