Follow-up to Adolescence after Early Peanut Introduction for Allergy Prevention
Du Toit G, Huffaker MF, Radulovic S, et al.
NEJM Evidence · 2024
What it found
Children who ate peanut from infancy to age five were followed to age twelve. At 144 months, peanut allergy was present in 4.4 percent of the early-eating group and 15.4 percent of the avoidance group. Protection held even though many children went years without eating peanut.
Why it matters here
This is the clearest existing proof that a cheap, early, non-pharmaceutical intervention can produce durable immune tolerance. It is the benchmark for what we mean by long-lasting and affordable.
Student project
Read the trial alongside its original 2015 report and chart how the primary endpoint, the population, and the claimed effect changed across three publications. Writing that history accurately is a real contribution and needs no lab.
