This bridging study is a randomized, double-blind, two arms parallel group, prospective intervention study. The primary objective of this study is to evaluate protectivity of DTP-HB-Hib Vaccine (Bio Farma) using new Hepatitis B bulk (Bio Farma).

This bridging study is a randomized, double blind, two arms parallel groups, prospective intervention study. Total 220 infants, 0-3 days old will be involved in this study. The subject will be divided into 2 groups, 110 subjects are the investigational group and 110 subjects are the active comparator group.

The objective of this study is to evaluate protectivity of DTP-HB-Hib Vaccine (Bio Farma) using new Hepatitis B bulk (Bio Farma) and to asses the safety of DTP-HB-Hib Vaccine (Bio Farma) and Recombinant Hepatitis B Vaccine using new Hepatitis B bulk (Bio Farma).
