Mechanism of action

GenHevac-B uses a recombinant hepatitis B surface antigen formulation to generate or enhance cellular and humoral immune responses in patients with chronic hepatitis B infection. By priming the immune system against HBsAg, the vaccine aims to facilitate viral clearance and functional cure in chronically infected individuals who have failed to mount adequate spontaneous immune responses.
