Study Arms:
- HB vaccine naive - HBVaxPro (Type: ACTIVE_COMPARATOR): Subjects have never been vaccinated with a Hepatitis B vaccine. Subjects are vaccinated with Hepatitis B vaccine HBVaxPro-10ug at day 0, 30, and 180.
- HB vaccine naive - HBAI20 (Type: EXPERIMENTAL): Subjects have never been vaccinated with a Hepatitis B vaccine. Subjects are vaccinated with Hepatitis B vaccine HBAI20 at day 0 and 30, and Hepatitis B vaccine HBVaxPro-10ug at day 180.
- Non-responders - HBAI20 (Type: EXPERIMENTAL): Subjects have been vaccinated 6 times with a Hepatitis B vaccine without developing a protective immune response, measured as anti Hepatitis B surface antigen antibodies, superior to 10mIU/ml.~Subjects are vaccinated with Hepatitis B vaccine HBAI20 at day 0 and 30, and Hepatitis B vaccine HBVaxPro-10ug at day 180.
