Outcomes
Primary Outcome Measures
Immunogenicity: HBV specific T-cell response by ELISPOT
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.
Secondary Outcome Measures
HBsAg titer
sample for HBsAg will be collected at each visit; VS(~4week), VT1(0week), VT2(8week), VF(16week. Change from baseline in HBsAg titer will be measured at VF.
