Which statement about vaccines for aircrew is accurate?

• A. Vaccines replace PPE
• B. Vaccines are not advised for aircrew
• C. The influenza vaccine is routinely recommended to reduce transmission risk.
• D. Only travelers require vaccines

Answer: (C)

Vaccination is part of a broader infection-control approach for aircrew, working together with PPE, hand hygiene, and illness policies to reduce the risk of disease transmission in the cabin. The influenza vaccine is routinely recommended for aircrew because influenza can spread rapidly in the close, enclosed environment of an aircraft. By reducing the likelihood that an individual aircrew member becomes infected, the vaccine also lowers the chance they will transmit influenza to colleagues and passengers, protecting both crew health and flight safety, especially during flu season.

Keep in mind that vaccines do not replace PPE or other protective measures; they are one layer of protection that complements gloves, masks when indicated, hygiene practices, and staying home when sick. Aircrew benefits come not only from protecting travelers but from reducing crew illness and downtime, which helps maintain operational readiness. The idea that only travelers need vaccines isn’t accurate—crew members are continuously exposed and travel with passengers, so routine vaccination, including influenza, is appropriate for them as well.
