Study: Patch raises peanut tolerance 10 times

Skin patches can help people stop smoking, and prevent pregnancies.

And soon there may also be a patch to help people - particularly children - become less allergic to peanuts.

Several hospitals have been developing and testing one.

And now a study shows some people, who wore one of the patches for a year, could eat at least 10 times more peanut protein than they could before treatment.

The patch, called Viaskin, has tiny amounts of peanut protein, which over time, make someone less sensitive to peanuts.

The biggest benefit was for kids ages 4-11.

Children over 12 didn't see as much improvement.

Last year, the FDA fast-tracked trials on the patch, hoping to get it to market faster.
