What is a major benefit of immunization programs for deployed troops?

• A. Increase illness during deployment
• B. Prevent illness during deployment
• C. Increase deployment time
• D. Replace need for preventive medicine

Answer: (B)

Immunization programs protect troops from diseases they might encounter in the field. The major benefit is preventing illness during deployment, which keeps soldiers ready, reduces medical evacuations, and preserves essential manpower when support is stretched thin. Vaccines train the immune system before exposure, so even crowded or austere environments are less prone to outbreaks. They’re part of a broader preventive medicine approach, not a substitute for other measures like hygiene, surveillance, and preventive care. Increasing illness, extending deployment time, or replacing preventive medicine would contradict the purpose of vaccination.
