Healthcare workers and infants at high risk are routinely immunised against the Hepatitis B virus (HBV). Which statement describes a scientifically accurate reason or biological mechanism for this health monitoring and maintenance strategy?
The vaccine introduces the recombinant Hepatitis B surface antigen (HBsAgHBsAgHBsAg) to induce active immunity, significantly reducing the host's long-term risk of developing chronic cirrhosis and hepatocellular carcinoma.
As HBV is a flagellated bacterium, the vaccine stimulates the production of specialized antitoxins that assist prescribed antibiotics in lysing the bacterial cell wall.
The vaccine delivers pre-formed monoclonal antibodies to provide immediate passive immunity that is cross-protective against all other blood-borne viral hepatitides, such as Hepatitis C.
The vaccine acts as a post-exposure therapeutic cure that targets and reverses established malignant liver tumours in individuals with advanced chronic infections.
