HBV surface antigen particles, prepared by recombinant DNA technology are described, said particles being composed of epitopes from the group of surface peptides and/or core peptide of non-A, non-B hepatitis virus, hepatitis virus A and/or hepatitis virus B. Respective particles are especially characterized by a composition of different epitopes selected from pre-S and S peptides. There are also described DNA-sequences, plasmids and cell lines coding for respective HBV surface antigen particles as well as a new vaccine containing the same.
