About

The purpose of this phrase III clinical trial is to evaluate the immunogenicity and safety of Sabin Inactivated Poliovirus Vaccine (Vero cell) in a '1+2' sequential schedule with bivalent oral poliovirus vaccine in 2-month-old infants

Full description

This study is a randomized, double-blind, active-controlled phrase III clinical trial. The purpose of this study is to evaluate the immunogenicity and safety of sIPV manufactured by Sinovac Vaccine Technology Co., Ltd in a '1+2' sequential schedule with bOPV in 2-month-old infants. 240 infants aged between 60-90 days will be randomly assigned into experimental group or control group in the ratio 1:1. The experimental group received sIPV-bOPV-bOPV vaccination schedule at one month doses interval (i.e., month 0, 1, 2), and the control group received wIPV-bOPV-bOPV vaccination schedule at one month doses interval (i.e., month 0, 1, 2). The control wIPV was manufactured by SANOFI PASTEUR S.A.
