Chemotherapeutic agents for Hepatitis B virus (HBV) suppression work, but only when administered to the patient. They do not appear to promote durable, long-term immunological control. After 3 years of effective anti-HBV therapy, a small percentage of patients maintained good control, manifest by controlled serum liver enzymes, low-level HBV-DNA, and controlled HBsAg concentrations. However, this did not occur in the majority of patients. We need a better understanding of the defects in HBV immunity and how to induce effective reconstitution that will maintain viral suppression, albeit either through innate or adaptive immunity.
