What is the recommended action after potential exposure to HBV?

The recommended action after potential exposure to hepatitis B virus (HBV) is to administer hepatitis B immune globulin (HBIG) and initiate the vaccination series within a specified timeframe, ideally within 24 hours of exposure. This approach is crucial because it provides immediate post-exposure prophylaxis that can significantly reduce the risk of the virus establishing an infection.

HBIG contains antibodies against HBV, which help to neutralize the virus and provide temporary immunity. Starting the hepatitis B vaccine series promptly also stimulates the body’s immune system to develop long-term protection against future infections.

While beginning vaccination within 48 hours is an action associated with prevention, it does not encompass the immediate use of HBIG, which is essential for maximizing protection right after an exposure event. Options involving daily health monitoring or immediate hospitalization are not appropriate responses to a potential HBV exposure, as they do not provide the immediate and proactive measures necessary for effective prophylaxis.
