At least one-third of the children who had immediate-type cow’s milk allergy at the age of 6 years tolerated cow’s milk by the age of 12 years. At 6 years of age, children with cow’s milk allergy and higher cow’s milk-specific immunoglobulin E, previous cow’s milk anaphylaxis, and complete cow’s milk elimination were less likely to tolerate cow’s milk by the age of 12 years.
