The presence of food-specific IgA antibodies in the gut does not prevent peanut or egg allergies from developing in children, according to a Northwestern Medicine study published in Science Translational Medicine.

Scientists examined from more than 500 infants across the country and found that the presence of Immunoglobulin A, the most common antibody found in in the , does not prevent peanut or from developing later in life.
