Studies have shown that while the vaccine contains trace amounts of egg protein, the risk of anaphylaxis or severe allergic reactions is extremely low for individuals with egg allergies. Therefore, the current guidelines from health authorities support the administration of the inactivated vaccine to those with egg allergies, emphasizing that they should be observed for a brief period after vaccination, particularly those with a history of severe allergic reactions to eggs.

In contrast, the live-attenuated influenza vaccine is not recommended for patients with severe egg allergies, as it poses a higher risk due to the potential for a more significant reaction. Additionally, administering prednisone before receiving the live vaccine is not a standard procedure and does not increase safety. Patients with egg allergies are generally advised against the live vaccine unless they have been evaluated and cleared by an allergist.

Thus, administering the trivalent inactivated influenza vaccine is the appropriate course of action,
