SYNTHETIC HEPATITIS B VIRUS VACCINE INCLUDING BOTH T CELL ANCB CELL DETERMINANTS

摘要

Chemically synthesized polypeptides include amino acid residue sequences that substantially correspond to the amino acid residue sequences of T cell and B cell determinant portions of a natural, pathogen-related protein, in particular, a hepatitis B virus surface antigen (HBsAg). When administered to a host alone, as polymers or as carrier-bound conjugates, the polypeptides induce the proliferation of thymus-derived cells in hosts primed against hepatitis B virus.
