Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary purpose of this study is to determine whether HepavaxGene TF is non-inferior to the comparator vaccine both at impeding hepatitis B transmission from mothers positive for chronic hepatitis B (Stratum 1) to their children and also in terms of seroconversion rate in children of mothers negative for chronic hepatitis B (Stratum 2) one month after completion of the immunization schedule.
