Protecting children from allergic reactions to peanuts may someday be as easy as putting on a patch.

A new wearable skin patch was recently tested - and it worked on over half of the children tested.

The year long study was funded by the National Institutes of Health.

The patch works by delivering small amounts of peanut protein, training the skin's immune system to tolerate increasing amounts.

Researchers found kids between the ages of 4 and 11 saw the biggest benefit, while those 12 and older didn't see as much of an effect at all.

The possibility of buying the patch over the counter is still a ways off, however. It would first need approval from the Food and Drug Administration.
