What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Immunogenicity: HBV specific T-cell response by ELISPOT
Time Frame: Change from Baseline in HBV specificic T-cell response at 16 weeks
sample for immunologic assay will be collected at each visit; VS(~4week), VT1(0week), VT2(8week), VF(16week. T-cell response will be measured by ex-vivo & cultured ELISPOT.
Change from Baseline in HBV specificic T-cell response at 16 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
