Which statement about Hepatitis B is true?

Which statement about Hepatitis B is true?

• A. Hepatitis B vaccine is available
• B. Hepatitis B vaccine is not available
• C. Hepatitis B is transmitted only via fecal-oral route
• D. Hepatitis B is not associated with Hepatitis D

Answer: (A)

Vaccination against Hepatitis B is available and provides protection by eliciting antibodies against the virus. Hepatitis B is transmitted through blood and body fluids—through sexual contact, shared needles, and from mother to child—not through the fecal-oral route, which is more typical of Hepatitis A. The HBV vaccine is a recombinant vaccine containing the viral surface antigen (HBsAg) and is highly effective in preventing both acute and chronic HBV infection. Because Hepatitis D requires the Hepatitis B surface antigen to replicate, vaccination against HBV also reduces the risk of Hepatitis D infection. The statements that the vaccine isn’t available or that transmission is exclusively fecal-oral are not correct.
