In an infection control plan, when should vaccination be considered?

• A. Only after all other measures fail
• B. Never
• C. When indicated
• D. For every patient

Answer: (C)

Vaccination is a preventive measure that should be built into an infection control plan and used when there is a valid indication based on risk assessment, exposure potential, and public health guidelines. The best approach is to consider vaccination when it is indicated for a person or a group, rather than applying it universally or never applying it. This means evaluating who needs vaccination, which vaccines are appropriate given age, health status, prior immunization, and local disease risk, and then implementing vaccination as part of the overall plan. For example, healthcare workers are often vaccinated against influenza and hepatitis B according to guidelines to reduce transmission and protect patients, while some individuals may have contraindications or specific circumstances where a vaccine is not indicated. So, vaccination should be considered when indicated, as part of a thoughtful, evidence-based infection control strategy.
