Milk Allergies and Immunizations

Children with milk allergies may have adverse reactions from DPT inoculation, physicians warn. MedPage Today (3/24, Susman) reported, "Some children highly allergic to milk products should be watched with caution when receiving the diphtheria, pertussis, and tetanus (DPT) vaccine because trace milk proteins in the vaccine could trigger reactions," according to findings presented at the American Academy of Allergy, Asthma & Immunology meeting. Physicians at the Mt. Sinai School of Medicine in New York City "identified seven patients who reported convincing allergic reactions to tetanus vaccines." The protein was identified as "casamino acids derived from cow's milk, contained in medium used to process the vaccines." The findings came from a "chart review of patients seen at Mt. Sinai who had reported allergic reactions after receiving the vaccine (primary or booster doses) from September 2007 to March 2010."
