Which hepatitis type currently has a preventive vaccine available in the United States?

• A. Hepatitis A
• B. Hepatitis B
• C. Hepatitis C
• D. Hepatitis D

Answer: (A)

Vaccination is available for some hepatitis viruses, and Hepatitis A has a preventive vaccine widely used in the United States. The Hepatitis A vaccine is inactivated and is given in two doses, usually starting at 12 months of age with a second dose 6 to 12 months later. It triggers the development of antibodies that protect against Hepatitis A infection, providing long-lasting immunity and reducing illness and transmission risk. Hepatitis B also has a vaccine and is commonly given as part of routine newborn immunization and for at-risk adults, offering protection against Hepatitis B and also reducing risk for Hepatitis D (which relies on Hepatitis B to infect). There is no vaccine yet for Hepatitis C. Hepatitis A’s vaccine is the best-known example of a preventive option among the choices.
