Does Food Allergy Require Any Change in Measles-Mumps-Rubella Vaccination?

OBJECTIVES

To determine the allergic reactions that develop after Measles and Measles-Mumps-Rubella (MMR) vaccination, and whether any delay in the timing of vaccination occurs in children with food allergy.

METHODS

Children with food allergy who were admitted to the Şişli Hamidiye Etfal Training and Research Hospital Healthy Child Clinic between 1st January 2015 and 30th June 2018 for Measles or MMR vaccination were studied retrospectively. Their age, delayed days of vaccination, the types of allergic food, the results of the specific IgE and skin tests, and any reaction after the vaccination were recorded.

RESULTS

During the study period, 159 patients were vaccinated and 170 doses of Measles or MMR vaccine were administered. Children allergic to egg were 50.3%, allergic to egg and milk were 25.8%, and 13.2% had multiple food allergy including egg. The rate of post-vaccination reactions in the patients with food allergy was 1.76%. Minor reaction was observed in three patients and no anaphylaxis was seen in any patient. Delayed days of vaccination in the patients referred by another center were greater than followed-up by present clinic (p < 0.001).

CONCLUSIONS

Any serious allergic reaction was not observed in this study. Food allergy does not necessitate modification of routine vaccination. Anaphylaxis may develop in any vaccinated child regardless of whether he/she has food allergy or not. Therefore, vaccines should be administered in a healthcare facility that can treat anaphylaxis.
