Outcomes

Primary Outcomes

Safety(proportion of subjects with adverse events)

The proportion of all adverse event and serious adverse event which were occured during the entire study period is analyzed and casuality between severity and investigational product is presented. Check the vital signs, physical examination and clinical laboratory tests

Time frame: From the date of the first orally administered for 4 weeks after the second dose

Secondary Outcomes

Immunogenicity(vibriocidal antibody assay)

Proportion of subjects exhibiting 4-fold or greater rises in titers of serum vibriocidal antibodies, relative to baseline

Time frame: Baseline(before the administration), 14 days after first dose, 14 days after second dose
