Immunogenicity and safety of adsorbed diphtheria-purified pertussis-tetanus-inactivated polio (Sabin strain)-Haemophilus type b conjugate combined vaccine (DPT-IPV-Hib) in healthy Japanese Infants ≥ 2 and < 43 months of Age: A phase III, multicenter, active controlled, assessor-blinded, randomized, parallel-group study.
Summary
The purpose of this study is to evaluate immunogenicity of BK1310 for all antigens (anti-PRP, diphtheria toxin, pertussis, tetanus toxin, and polio virus), after 3 times of injection, when compared noninferiority with co-administration of ActHIB® and Tetrabik, as well as efficacy and safety, in healthy infants.
