Abstract
Method for the production of antigens vaccinating against the virus of B viral hepatitis. It consists of transforming a cell culture with a vector, more particularly a plasmid, itself containing an insertion sequence including itself at least the part of the viral DNA coding for the immunogen protein, capable of inducing in vivo antibody production active with respect to the whole virus, as well as the viral promoter under the control of which the transcription and translation of the above-said part of viral DNA is normally carried out, in particular in a host infected with the corresponding virus.
