A Phase II/III Study to Evaluate the Immunogenicity, Safety and Lot-to-lot Consistency of LBVD, a Fully Liquid Hexavalent Diphtheria-tetanus-whole Cell Pertussis-hepatitis B-poliovirus-Haemophilus Influenzae Type b Conjugate (DTwP-HepB-IPV-Hib) Vaccine, in Healthy Infants as Primary Series

The purpose of this study is to evaluate immunogenicity, safety and lot-to-lot consistency of LBVD in comparison to co-administration of Pentavalent vaccine and Poliomyelitis Vaccine (Inactivated) in separate injections at four weeks after completion of three-dose primary series at 6-10-14 weeks of age when administered to healthy infants

Stage 1 (Phase 2) 1\. To compare the immunogenicity and safety of LBVD to the licensed Control vaccines at 4 weeks after a three-dose primary series of vaccination given at 6-, 10- and 14-week of age Stage 2 (Phase 3) 1. To demonstrate the non-inferior immunogenicity of LBVD to the licensed Control Vaccine at 4 weeks after a three-dose primary series of vaccination given at 6-, 10- and 14-week of age 2. To demonstrate lot-to-lot consistency in the immunogenicity of three separate lots of LBVD at 4 weeks after a three-dose primary series of vaccination given at 6-, 10- and 14-week of age
