What is the key preventive measure for Hepatitis B?

• A. Hepatitis A vaccine
• B. HPV vaccine
• C. Influenza vaccine
• D. Hepatitis B vaccine

Answer: (D)

Vaccination against hepatitis B is the most effective way to prevent infection. The hepatitis B vaccine prompts the body to produce protective anti-HBs antibodies, leading to high peak protection in most people and long-lasting immunity. This prevents both acute hepatitis B and the risk of chronic infection, which in turn lowers the chance of severe liver disease later on. Vaccination is recommended for all newborns and for adults at risk (such as healthcare workers, injection drug users, and sexual partners of infected individuals). The other vaccines listed protect against different diseases (Hepatitis A, HPV-related conditions, and influenza) and do not prevent Hepatitis B, so they aren’t preventive measures for HBV. Therefore, the hepatitis B vaccine is the key preventive measure.
