If a patient with an egg allergy experiences hives after an influenza vaccination, what is the ACIP's recommendation?

Patients with a history of egg allergy can generally receive the influenza vaccine, especially if their allergic reaction is limited to hives. The Advisory Committee on Immunization Practices (ACIP) specifically states that individuals who have experienced only hives after consuming eggs can be safely vaccinated against influenza. This is because the risk of a severe allergic reaction, such as anaphylaxis, is much lower in those who only have hives as a symptom.

It is important to note that while some influenza vaccines are produced using egg-based technology, the proteins present in the vaccine are in such small quantities that they typically do not provoke a severe allergic response in those with mild egg allergies. Therefore, for patients who experience only hives, administration of the vaccine can be done in a routine setting rather than requiring special precautions or locations, such as an emergency room. This guidance helps ensure that individuals with egg allergies are adequately protected from influenza through vaccination while minimizing unnecessary anxiety about getting vaccinated.
