Many children are diagnosed with egg allergy at a young age, although many will outgrow this allergy before they reach adolescence. Some children are told that they are egg allergic based on a positive allergy test to egg; although they can eat eggs without experiencing any symptoms. People who can eat eggs without experiencing symptoms of food allergies can safely receive the influenza vaccine despite the positive allergy test to egg.
If a person has a true allergic reaction from eating eggs, it is still possible for them to receive the influenza vaccine under the direct care of an experienced allergist. The vaccine is given in divided amounts over many hours, with close monitoring for an allergic reaction. This process is called a vaccine progressive challenge, which is frequently used in the military to ensure all possible personnel are vaccinated for public health reasons. The decision to perform a vaccine challenge is based on the persons risk from not being vaccinated to the potential risk of having an allergic reaction to the vaccine.
