The present disclosure relates to hybrid hepadnavirus core antigens including one or more epitopes of a human hepatitis B vims (HBV) antigen. More specifically, the present disclosure relates to hybrid hepadnavirus core antigens in the form of fusion proteins containing a fragment of the PreS1 region of the HBV surface antigen inserted in a woodchuck hepadnavirus core antigen. The present disclosure further relates to hybrid hepadnavirus core antigens in the form of fusions proteins containing a truncated HBV core antigen and woodchuck hepadnavirus core antigen. Also provided are nucleic acids encoding the hybrid core antigens, and the use of the hybrid core antigens and nucleic acids for treating HBV-infected individuals.
