ABSTRACT:
Nucleotide composition containing a vector and vaccine for immunization against hepatitis. Nucleotide vector comprising at least one gene or one complementary DNA coding for at least a portion of a virus, and a promoter providing for the expression of the gene in muscle cells. The gene may be the S gene of the hepatitis B virus. A nucleotide vector composition when administered to even chronic HBV carriers is capable of breaking T cell tolerance to the surface antigens of hepatitis B virus. A vaccine preparation containing bare DNA is injected into the host previously treated with a substance capable of inducing a coagulating necrosis of the muscle fibers.
