Vaccine Could Stop Peanut Allergies By Changing How Immune System Reacts

A vaccine is currently in development that might one day lead to a cure for the peanut allergy. Researchers at the University of Michigan have developed a nasal spray that, when administered monthly, prevents mice from having allergic reactions to peanut products. The researchers have spent nearly 20 years working on a way to immunize patients against peanut allergies, according to the University of Michigan.
