Study methodology

The study tested 1,275 babies under 18 months with peanut allergy diagnoses using medical supervision.
Oral food challenge results
Of 778 babies given increasing peanut amounts, 65% had reactions and 12% had potentially life-threatening reactions.
Study lead
Tim Brettig, a pediatric allergist and immunologist who helped lead the study, said they didn't expect this many children to pass food challenges.
NIH guidelines
NIH now advises freely introducing peanuts to infants with no eczema or food allergies.
