Vaccine Information

There is no vaccine to prevent hepatitis D, however being vaccinated for hepatitis B provides protection from hepatitis D. This is because only people living with hepatitis B or simultaneously infected with hepatitis B and D are at risk of contracting hepatitis D.

In 2022 the Advisory Council on Immunization Practices (ACIP) updated vaccination guidelines to include people between the ages of 19 and 59 years, and those 60 years and over upon request.

Diagnosis & Management

Hepatitis D is diagnosed with anti-HDV immunoglobulin G (IgG) and immunoglobulin M (IgM) and confirmed by detection of HDV RNA in an antibody blood test. Positive results could indicate an acute, chronic, or past infection. Patients with HDV coinfection experience higher rates of HCC and more rapid progression of liver disease than patients with HBV alone.
