The Hepatitis B vaccine is available within how many days of starting occupational exposure duties?

• A. 7 days
• B. 10 days
• C. 12 days
• D. 14 days

Answer: (B)

After exposure to hepatitis B in the workplace, the key step is to start vaccination promptly to give your body a chance to build protective antibodies before infection can take hold. The window highlighted here is within ten days of exposure. Beginning the vaccine within this period maximizes the likelihood of developing immunity quickly, which lowers the risk of acquiring hepatitis B from that exposure. If a person is not immune or has an uncertain immunity status, vaccination should be initiated as soon as possible, and the full series should be completed over time. In some protocols, additional post-exposure measures may be considered depending on timing and risk, but the essential point the question tests is starting the hepatitis B vaccine within ten days to optimize protection.
