Among egg allergy histories, which history allows influenza vaccination with any influenza vaccine appropriate for age and health status?

• A. Experiencing only hives after egg exposure
• B. Anaphylaxis to eggs
• C. Wheezing after egg exposure
• D. Hypotension after egg exposure

Answer: (A)

The key idea is that the severity of an egg allergy determines how vaccination is given. If someone has only hives after egg exposure, this is considered a mild, skin-limited allergic reaction and does not require special precautions for influenza vaccination. Current guidelines allow individuals with this history to receive any licensed influenza vaccine appropriate for their age and health without additional restrictions. In contrast, reactions involving the airways or circulation after egg exposure—such as wheezing, low blood pressure, or a full anaphylactic reaction—signal a higher risk of a systemic reaction to egg-based vaccines. For those histories, vaccination should be done in a setting where appropriate care is available, and consideration should be given to vaccine choice or delivery method that minimizes egg protein exposure. So, only hives after egg exposure fits the scenario where influenza vaccination can proceed with standard practice, without special precautions beyond routine post-vaccination observation.
