Scientists stop allergy symptoms with a peanut patch.

Children from 4 to 11 years of age have learned to treat with skin immunotherapy - a patch with 250 micrograms of peanut protein. This is much less than in other treatments, which means less risk of side effects. Now scientists have tested the effectiveness of this method of treatment for children under four years old. The study included 362 children from 8 countries. After a year, 67% of the study group were able to eat from one to four peanut "nuts".
