About The Cover
COVER Between 1 and 2% of people in the United States are allergic to peanuts. A new treatment strategy exposes affected children to peanuts or peanut proteins in hopes of desensitizing their immune system. This approach has gained popularity as doctors in private practice offer it and two commercial products are nearing potential approval. But it also comes with risks and uncertainties. See page 278.
