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

The correct recommendation in this scenario is to administer the cell culture-based (ccIIV) or recombinant influenza vaccine (RIV). This is rooted in guidelines from the Advisory Committee on Immunization Practices (ACIP), which state that individuals with a history of egg allergy who experience hives after exposure to egg products should be vaccinated with either a cell culture-based or recombinant influenza vaccine.

This approach is founded on the understanding that these specific vaccines do not contain egg protein or contain it in very minimal amounts, making them safer options for patients with egg allergies who have had an allergic reaction such as hives to previous vaccinations. The ACIP encourages the use of these alternatives to prevent severe allergic reactions while still ensuring the patient receives the necessary vaccination against influenza.

The other options would not align with best practices as they may involve vaccines that contain higher levels of egg proteins, potentially putting the patient at risk for a more severe allergic reaction. This is particularly crucial considering the severity of reactions can vary drastically among individuals with allergies. Thus, the recommendation effectively balances safety and the necessity of vaccination for influenza.
