A prospective, multicentre, comparative, double blind, randomized phase III study to assess immunogenicity and safety of LBVW0101 (Diphtheria-Tetanus-whole cell Pertussis- Hepatitis B) compared with Tritanrix HB® (Diphtheria-Tetanus-whole cell Pertussis-Hepatitis B) and to demonstrate the equivalence of three different lots of LBVW0101, in terms of immunogenicity, in healthy infants at six, ten, and fourteen weeks of age.

简要总结
This is a prospective, multicentre, comparative, parallel, double-blind, randomised phase III study to assess immunogenicity and safety of LBVW0101 (Combined DTwP-HB vaccine) compared with Active Comparator Tritanrix-HB (Combined DTPw-HB Vaccine) and to demonstrate the equivalence of three different lots of LBVW0101, in terms of immunogenicity, in healthy 492 subjects. (infants at six, ten and fourteen weeks of age).
