presents to his primary care physician for a well-child examination and routine immunization. In the time between his first measles-mumps-rubella (MMR) vaccine and now, he has developed severe atopic dermatitis. Evaluation by an allergist/immunologist revealed IgE-mediated allergy to egg, soy, and peanut. He has had anaphylaxis after eating peanut, and eating eggs results in urticaria and worsening of his atopic dermatitis. His mother read that MMR vaccine is produced from eggs and is concerned about a possible reaction. What is the next course of action for this patient?
a.Proceed with the vaccination
b. Refer the patient for desensitization to egg protein and then proceed with immunization
c. Delay vaccination because of the history of documented egg allergy
d. Repeat skin prick testing and, if negative, proceed with immunization
e. Use gradually increasing doses of the vaccine to decrease the risk of a reaction

What about egg allergy and vaccine allergy? The link between the two is that some vaccinations, including the MMR and Influenza vaccines are made using chicken egg or related substances. In theory, if one is allergic to eggs, then one may be allergic to egg-based vaccines. This is what we thought years ago and as a result, many egg-allergic children automatically did not receive the MMR vaccine because of this fear. However, allergy tests can be performed on any vaccine. So, to be sure, doctors can perform an allergy test for the MMR vaccine itself. If, based on the allergy test, an egg-allergic child is not allergic to the MMR vaccine, he or she receives the MMR vaccine without any problem. After years of this approach, it was realized that very, very few egg-allergic children were actually allergic to the MMR vaccine. As a result, current expert recommendations are to go ahead an vaccinate egg-allergic children with the MMR vaccine without any specific MMR allergy testing. So in reality, the relationship with egg allergy and the MMR vaccine is just in theory, as almost all egg-allergic children can receive the MMR, egg-based vaccine without a problem. However, this does not apply to other egg-based vaccines like the flu vaccine. In this case, if a child is allergic to eggs, he or she should not receive the vaccine unless specific "flu- vaccine allergy tests" are performed by an allergist. There seem to be some people that despite having an egg allergy are not allergic to the fu vaccine when tested.
