Abstract
The invention concerns a composition useful for the manufacture of vaccines containing particles having the immunogenic properties characteristic of the antigen HBsAg, these particles being more particularly characterized by the fact that the particles equally contain a receptor for polymerized human albumin. They are obtained by transformation of human or animal cells by a vector containing a DNA sequence coding for the S and pre-S regions of a genome of viral hepatitis B, this DNA sequence being placed under the direct control of a promoter permitting the effective transcription of the sequence in the human or animal cells transformable by the vector.
