Primary Outcome Measures:
- Immunogenicity: HBV specific T-cell response by ELISPOT [ Time Frame: Change from Baseline in HBV specificic T-cell response at 16 weeks ] [ Designated as safety issue: No ]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 [ Time Frame: Change from baseline in HBsAg titer at 16 weeks ] [ Designated as safety issue: No ]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.
