Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Chronic HBV infection is major problem in Asian countries. Years after chronic infection, in some cases serum HBsAg level declines to unmeasurable level. Some of patients develop anti-HBsAb but there is no standard treatment to accelerate HBsAg seroconversion.

There is a study to determine efficacy and safety of HBV vaccine in who is Chronic HBV infection and lost their HBsAg without seroconversion to anti-HBsAb.
