Peanut allergies are one of the most common food allergies and can cause deadly allergic reactions. In the past, doctors have tried under-the-tongue therapies, to help people with peanut allergies, but they had only moderate success.
Now researchers are experimenting with a new patch that contains peanut protein. Children wear it every day for at least two and a half years. Reserachers want to know if repeated exposure to peanuts can actually desensitive children.
According to Dr. HUgh Sampson, who's conducting the study at the Mount Sinai Hospital, "this protein gets into the outer layer of the skin, is taken up by specialized cells that then take it to the inner parts of the immune system."
Dr. Sampson says the study is being conducted at 24 centers worldwide. He says the initial goal is for children to build a resistance to peanuts.
