In infection control, vaccines are described as an essential layer of protection alongside what?

• A. PPE and hand hygiene
• B. Antibiotics
• C. Sterilization
• D. Public health surveillance

Answer: (A)

Infection control uses a layered approach, where vaccination reduces the risk of illness but must be complemented by immediate protective practices during care. PPE and hand hygiene form the essential barrier between healthcare workers and pathogens, providing a physical and behavioral shield during every patient contact. Vaccines lower susceptibility and, in some cases, transmission, but PPE and proper hand hygiene are the frontline defenses that prevent exposure from occurring or spreading if exposure happens. Other options don’t function as that ongoing protective layer: antibiotics treat existing infections, sterilization focuses on equipment cleanliness rather than daily protection during care, and public health surveillance detects outbreaks rather than preventing transmission in the moment.
