Egg allergy: are all childhood food allergies the same?
Egg allergy is one of the most common food allergies in childhood affecting about 1-2% of preschool children and differs in a number of ways from other common childhood food allergies such as cows milk and peanut. Common egg allergens are altered both by heat and gastric enzymes. Compared with peanuts/tree nuts and milk, egg allergy appears less likely to cause severe life-threatening reactions or fatal anaphylaxis. Children are much more likely to outgrow egg allergy by school age as compared with peanut allergy. While the MMR vaccine is no longer contraindicated in egg allergy, influenza vaccine is contraindicated in children with anaphylaxis to egg. An understanding of the similarities and differences in these common food allergies of childhood is helpful in the management of these common and increasing problems.
