A high rate of chronic HBV infection in China is mainly the result of perinatal or early childhood transmission. Therefore, universal vaccination against HBV in infants has been very successful in the control of chronic HBV infection, with the prevalence of hepatitis B surface antigen decreasing from nearly 10% to approximately 7% in the general population. Adoption of Good Clinical Practice and proper conduction of well-designed clinical trials on conventional and pegylated interferons and nucleos(t)ide analogs have generated important clinical data. The publication and promotion of the evidence-based national guidelines have greatly improved the standard of clinical practice on the prevention and treatment of chronic hepatitis B. The ongoing national key scientific projects on the optimization of vaccination strategy and current anti-HBV therapy will yield important clinical evidence. Inclusion of conventional and pegylated interferons and nucleos(t)ides into the new national reimbursement list will increase the availability and affordability of anti-HBV therapies, thereby further decreasing the morbidity and mortality associated with chronic HBV infection.
