Why are vaccines important for aircrew, and name one routinely recommended vaccine?

• A. They are optional and not necessary for flight safety
• B. They are primarily for long-term travel health outside aviation
• C. They only protect against gastrointestinal infections
• D. They reduce infection risk and transmission; influenza vaccine is routinely recommended

Answer: (D)

Vaccines help keep aircrew medically ready by lowering the chance of infections that could impair performance and by reducing the likelihood of spreading illness to fellow crew and passengers in the tight, high-contact environment of an aircraft. If a crew member becomes sick, flight duties may be disrupted and cognitive or physical performance can suffer, which poses safety risks. Vaccination minimizes these risks and supports mission readiness by limiting both individual illness and transmission within the crew and to passengers. One routinely recommended vaccine is the influenza vaccine, given annually to reduce the likelihood of flu infection and transmission and to decrease sick days among aircrew.
