Approximately 350-400 million people worldwide are chronically infected with the hepatitis B virus (HBV). These individuals harbor the virus for their whole life and they transmit the virus to uninfected individuals. In addition, considerable numbers of chronic HBV carriers develop progressive liver diseases like chronic hepatitis B, liver cirrhosis and hepatocellular carcinoma. At present, antiviral agents like type-1 interferons, lamivudine, adefovir and entacavir are used to treat a selected population of chronic HBV carriers. These antiviral treatments are not satisfactory in that they are unable to eradicate HBV, only partially efficient in less than 30% subjects, expensive, can have debilitating side-effects and require constant monitoring. In addition, once treatment is stopped, the virus and clinical conditions return in many patients. Recent advancements in cellular and molecular biology indicate that the host's immune responses to HBV play cardinal roles during acquisition, pathogenesis, progression, and complications of chronic HBV infection. Immune responses are also important in the context of antiviraltherapy and clinical recovery. This explains why the efficacy of antiviral drugs is limited even in some selected patients with chronic HBV infection. Various published work now state that HBV-specific immunity may be beneficial for patients with chronic HBV infection and non-HBV-specific immunity may be related to flare up of liver diseases. Accordingly, a new few field of immunological research and clinical application of prophylactic vaccines (vaccine therapy) has been started in chronic HBV carriers. Vaccine therapy has inspired optimism as a new therapeutic approach, but it is unlikely that the present regimen of vaccine therapy will stand the test of time. Based on present understandings about vaccine/host interactions, we provide herein an outline for engineering more potent regimen of HBV-specific immune therapy against HBV.
