Which vaccination is recommended for researchers who work with serum, blood, or tissues from humans or ape?

• A. Simian Immunodeficiency Virus
• B. Q fever
• C. B virus
• D. Hepatitis B

Answer: (D)

Handling serum, blood, or tissues from humans or nonhuman primates poses a real risk of bloodborne infections. The hepatitis B virus is a major occupational hazard in these settings because it can be transmitted through contact with infected blood or bodily fluids, and it can survive on surfaces. The hepatitis B vaccine provides strong, long-lasting protection and is routinely offered to laboratory personnel with exposure risk. It’s given as a series of injections and is highly effective at preventing HBV infection, making it the recommended vaccination for researchers working with human or ape samples. Other options either refer to pathogens or exposures not addressed by a standard vaccination in this context (for example, there is no widely used human vaccine for B virus, and Q fever vaccines are targeted more toward livestock exposure rather than routine handling of human or primate tissues).
