The results of the first successful U.K. study into oral tolerance involving severe peanut allergies have been announced by the Department of Allergy, Addenbrooke's Hospital, Cambridge.

In a small study led by Dr. Andrew T. Clark, peanut oral immunotherapy (OIT) was investigated as to whether it could induce clinical tolerance to peanut protein in four peanut allergic children.

Immunotherapy is a treatment strategy that aims to desensitise the immune system by gradually increasing dose of the substance to which a person is allergic to.
