Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the lot consistency, immunogenicity and safety of three lots of Sabin strain inactivated polio vaccine (Vero Cell) (sIPV) manufactured at commercial scale by Sinovac Biotech Co., Ltd., and evaluate the non-inferiority of investigational vaccine against a post-market inactivated polio vaccine.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is a randomized, double-blinded, and positive-controlled clinical trial. A total of 1300 infants aged 2 months will be enrolled and assigned to 4 groups in a ratio of 1:1:1:1 to receive vaccination of 3 lots of investigational sIPV and control IPV manufactured by Sanofi Pasteur S.A respectively. Each subjects should finish the three-doses primary vaccination at the schedule of 2,3,4 months of age. Thirty-days safety observation after each dose of vaccination will be carried out. Venous blood should be collected from all the subjects before and 30 days after the three-doses primary vaccination, for the neutralizing antibody assay, and further to evaluate the immunogenicity.
