A Multi-center, Open-labelled, Randomized, Controlled, Extended Phase Ⅲ Clinical Trial of sIPV Vaccine

Summary

This study is designed to study the immunogenicity and safety of sIPV co-administered with other routine infant vaccines. According to the national immunization schedule of Bangladesh and Pakistan, sIPV was administered concomitantly with PCV10, DTP-HeB-Hib and other vaccines at 6, 10 and 14 weeks old. Thus, this study set up the concomitant vaccination schedule according to the real practice in study area. The primary hypothesis of this study is the seroconversion rate of polio vaccination when administered concomitantly with routine vaccines, is non-inferior to that when administered alone; the secondary hypothesis of this study is the seropositivity rate of diphtheria, tetanus, and pertussis when routine vaccines are administered concomitantly with sIPV, is non-inferior to that administered without sIPV.
