Brief summary
This trial is an experimental, randomized, double blind, prospective intervention study Approximately 100 subjects will be enrolled in this trial, divided into 2 arms, as follow: For adult (18-40 years old)
Detailed description
Each study age group/arm will be divided into two groups of treatment. One group will receive investigational product and one other group will receive active comparator. This Study is sequential age de-escalation. To be conducted in heathy adults (18-40 years old) and followed by children (10-17 years old) ). Before the study started, the subjects will be assessed for anti HBs Antibody. For subjects with anti-HBs not protective (\< 10mIU/mL) before immunization, additional 2 doses will be required with 1 month interval.
