Primary Outcome Measures
NameTimeMethod
Immunogenicity: HBV specific T-cell response by ELISPOTChange 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.

Secondary Outcome Measures
NameTimeMethod
HBsAg titerChange from baseline in HBsAg titer at 16 weeks

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.
