Explanation

Hepatitis B virus (HBV) is a blood-borne pathogen, and healthcare workers (HCWs) are at high occupational risk of exposure through needlestick injuries or contact with contaminated blood and body fluids.
Regulatory bodies and health organizations mandate the Hepatitis B vaccine for HCWs to ensure their safety and prevent the spread of the virus within the healthcare setting.
The vaccine is administered as a three-dose series and is highly effective, providing 90-95% protection in healthy adults.
Unlike other hepatitis viruses listed, HBV poses the most direct and common occupational risk that is preventable by a readily available vaccine.

Option A: Hepatitis A is primarily transmitted through the fecal-oral route (contaminated food and water). While a vaccine exists, it is not routinely recommended for all healthcare workers, only for those with specific risk factors like travel to endemic areas or during an outbreak.
Option C: There is currently no vaccine available for Hepatitis C. Prevention for HCWs relies on strict adherence to standard precautions, safe injection practices, and proper handling of sharps to avoid exposure to this blood-borne virus.
Option D: Hepatitis E is transmitted via the fecal-oral route, similar to Hepatitis A. A vaccine is not widely available or routinely recommended for healthcare workers in most countries.

Clinical Relevance

Nursing practice connection: Knowing Immunization requirements for healthcare workers helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
HBV vaccination is a cornerstone of occupational health and safety in healthcare, protecting staff from a serious, potentially chronic liver disease that can lead to cirrhosis and hepatocellular carcinoma.
Nurses play a vital role in educating colleagues about the importance of vaccination, ensuring their own immune status is up-to-date, and following post-exposure protocols meticulously to prevent infection.
What if? If a vaccinated HCW is tested and found to have an anti-HBs antibody titer of less than 10 mIU/mL, they are considered a non-responder or to have lost immunity. They would require a booster dose or a repeat vaccine series and would need post-exposure prophylaxis (HBIG + vaccine) if exposed to HBV.

How to Approach the Question

First, identify the core of the question: It asks for a vaccination that is required for ALL hospital staff.
Consider the primary occupational hazards in a hospital. Exposure to blood and body fluids is a major and universal risk.
Evaluate each option based on the virus's mode of transmission. Hepatitis A and E are primarily fecal-oral, which is not a universal high-risk pathway for all hospital staff.
Hepatitis B and C are blood-borne. This aligns with the primary occupational risk.
Finally, recall or determine which of the blood-borne viruses has a mandatory vaccine for HCWs. A vaccine for Hepatitis C does not exist, leaving Hepatitis B as the only correct answer.
