Explanation

Healthcare workers (HCWs) are at a significant occupational risk for acquiring Hepatitis B virus (HBV) infection due to potential exposure to blood and other infectious body fluids.
Hepatitis B is a bloodborne pathogen, and its transmission in a healthcare setting is a well-documented risk, primarily through percutaneous injuries like needlesticks.
Because of this high risk, universal vaccination against Hepatitis B is recommended for all HCWs who do not have prior immunity.
The standard vaccination protocol involves a 3-dose series, followed by post-vaccination serologic testing to confirm the development of protective antibodies (anti-HBs).

Option A: Hepatitis A virus is primarily transmitted through the fecal-oral route (contaminated food and water), which is not a primary occupational hazard for all healthcare workers.
Option C: There is currently no licensed vaccine available to prevent HIV infection.
Option D: Polio vaccination is part of the routine childhood immunization schedule. Most adults, including HCWs, are already immune. It is not a vaccine specifically required due to occupational risk in healthcare.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Occupational health and safety immunization for healthcare workers as background academic context rather than a clinical decision trigger.
Vaccination against Hepatitis B is a fundamental component of infection control programs in healthcare settings, protecting both the staff and their patients from potential transmission.
In India, as in many other countries, most healthcare institutions mandate Hepatitis B vaccination or documented proof of immunity as a condition of employment for clinical staff.
What if? A vaccinated HCW is exposed to an HBsAg-positive source, but their post-vaccination antibody titer was never checked. The HCW should be tested for anti-HBs immediately. If the level is adequate (greater than or equal to 10 mIU/mL), no treatment is needed. If inadequate, they should receive both HBIG and a vaccine booster dose.

How to Approach the Question

Identify the core of the question: it asks for a vaccine that all health workers should have, implying a universal occupational risk.
Consider the primary risks for healthcare workers, which prominently include exposure to blood and body fluids.
Evaluate each option's mode of transmission: Hepatitis B (bloodborne), Hepatitis A (fecal-oral), HIV (bloodborne), and Polio (fecal-oral).
Eliminate options that don't fit the 'universal' criteria. Hepatitis A and Polio are not universal risks for all HCWs.
Eliminate the HIV option because a vaccine does not exist.
This leaves Hepatitis B, a serious bloodborne disease for which a safe and effective vaccine is available and universally recommended for HCWs to mitigate occupational risk.
