简要总结
The aim of the study is to assess the immunogenicity of SP059 (IMOVAX POLIO®: Inactive Poliovirus Vaccine) vaccine against poliovirus and safety after fifth dose.
Primary Objective:
- To investigate the booster vaccine response rate against poliovirus types 1, 2 and 3 one month following the vaccination dose with SP059 as 2nd booster
Secondary Objectives:
- To investigate seroprotection rates (percentage of subjects presenting poliovirus neutralizing antibody titers above 1:8 (1/dil.) at pre- and post-booster time points, Geometric mean titers (GMT) at pre- and post-booster time points and geometric mean of individual titer ratio (GMTR).
- To investigate the safety after dosing of SP059 as 2nd booster.
详细描述
Participants will receive one dose of SP059 (at Visit 1) as a booster vaccination at an age from 4 to 6 years. They will be assessed for immunogenicity at baseline (pre-vaccination) and at 4-6 weeks post- vaccination.
Safety data including serious adverse events (SAEs) after vaccination will be collected during the study period.

结局指标
主要结局
Percentage of Participants With Booster Responses Against Polio Antigens Following Vaccination With IMOVAX POLIO®
时间窗: Day 28 post-vaccination
A booster response was defined as a 4-fold increase from pre-booster to post-booster vaccination. Anti-polio virus antibodies were assessed by virus neutralization assay.
次要结局
- Geometric Mean Titers of Vaccine Antigens Before and After Vaccination With IMOVAX POLIO®(Day 0 (pre-booster vaccination) and Day 28 post-booster vaccination)
- Percentage of Participants With Seroprotection Against Polio Antigens Before and After Booster Vaccination With IMOVAX POLIO®(Day 0 (pre-booster vaccination) and Day 28 post-booster vaccination)
- Geometric Mean of Individual Titer Ratios of Vaccine Antigens Following Booster Vaccination With IMOVAX POLIO®(Day 28 post-booster vaccination)
- Number of Participants Reporting a Solicited Injection Site or Systemic Reaction Following Booster Vaccination With IMOVAX POLIO®(Day 0 up to Day 7 post-vaccination)
