Safety and Immunogenicity of a Sabin Inactivated Poliovirus Vaccine

A Phase I Study to Evaluate the Safety and Immunogenicity of a Sabin Inactivated Poliovirus Vaccine (Vero Cell)

• Status: Completed
• Phase: Phase 1
• Study type: Interventional
• Enrollment: 100 (actual)
• Sponsor: Jiangsu Province Centers for Disease Control and Prevention · Network
• Sex: All
• Age: 60 Days – 45 Years
• Healthy volunteers: Accepted

Summary

The purpose of this phase I study is to evaluate the safety of a Sabin Inactivated Poliovirus Vaccine (sIPV) in adults and children, and the safety and immunogenicity of it in infants. 20 adults aged 18\~45 years and 20 children aged 4 years were only administered one dose of sIPV with medium D antigen content. 60 infants aged 2 months (60\~90 days) were randomized to receive three doses of sIPV with medium D antigen content, conventional IPV (cIPV, manufactured by Sanofi Pasteur) or sIPV (manufactured by the Institute of Medical Biology, the Chinese Academy of Medical Biology), respectively, on the month 0, 1, 2 schedule. Serum samples were collected before the 1st dose and 30 days after the 3rd dose vaccination to assess the immunogenicity in infants. Adverse events occurring within 30 days after each dose were collected to assess the safety.

Detailed description

The purpose of this phase I study is to evaluate the safety of a Sabin Inactivated Poliovirus Vaccine (sIPV) in adults and children, and the safety and immunogenicity of it in infants. 20 adults aged 18\~45 years and 20 children aged 4 years were only administered one dose of sIPV with medium D antigen content. 60 infants aged 2 months (60\~90 days) were randomized to receive three doses of sIPV with medium D antigen content, conventional IPV (cIPV, manufactured by Sanofi Pasteur) or sIPV (manufactured by the Institute of Medical Biology, the Chinese Academy of Medical Biology), respectively, on the month 0, 1, 2 schedule. Serum samples were collected before the 1st dose and 30 days after the 3rd dose vaccination to assess the immunogenicity in infants. Adverse events occurring within 30 days after each dose were collected to assess the safety. The antigen contents of type I, type II and type III polioviruses in the investigational and control vaccines were as follows: medium-dose Sabin IPV (15 DU, 45 DU and 45 DU), control Sabin IPV (30 DU, 32 DU and 45 DU), control Salk IPV (40 DU, 8 DU and 32 DU). All vaccines were in liquid form, 0.5 ml per dose.
