Why is Hepatitis B vaccination recommended in dialysis units?

• A. To prevent hepatitis B transmission among patients and staff.
• B. To reduce fever during dialysis.
• C. To improve dialyzer clearance.
• D. To prevent infections in visitors.

Answer: (A)

Vaccination against hepatitis B in dialysis units is about stopping the spread of the virus among people who are most exposed to blood and blood products—the patients and the staff. Hepatitis B is highly infectious and can be transmitted through blood, needle sticks, and other exposures that can occur in a dialysis setting where vascular access and shared equipment are routine. When individuals complete the vaccine series, they develop protective antibodies that prevent infection, so both the vaccinated person is protected and the chance of transmitting the virus to others is reduced. This makes the vaccination program a cornerstone of infection prevention in the unit. The vaccine’s purpose isn’t to reduce fever, improve dialyzer performance, or prevent infections in visitors—those outcomes aren’t achieved by HBV vaccination, whereas preventing HBV transmission in the unit is achieved by immunizing those at risk.
