Detailed 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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The difference between experimental group and control group of type I,III neutralizing antibody seroconversion rate after primary immunization. And the lower limit of 95% confidence intervals of the difference value.
Time Frame: 30 days
Subjects whose pre-immune antibody level < 1:8 and post-immune antibody level ≥ 1:8, or those whose pre-immune antibody level ≥ 1:8 and the increase of post-immune antibody level ≥ 4 folds are considered seroconverted. Primary vaccination schedule: 3 doses with one month interval between doses (i.e., month 0, 1, 2).
30 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The incidence of unsolicited AE within 30 days after each dose of each group.
Time Frame: 30 days
Unsolicited AEs occurred within 30 days after each injection will be collected.
30 days
Type I,II and III neutralizing antibody positive rate of each group after primary immunization
Time Frame: 30 days
Subjects whose post-immune antibody level ≥ 1:8 are considered antibody positive. Primary vaccination schedule: 3 doses with one month interval between doses (i.e., month 0, 1, 2).
30 days
Type I,II and III post-immune geometric mean titer (GMT) of each group after primary immunization.
Time Frame: 30 days
GMT of each group after primary immunization
30 days
Type I,II and III post-immune geometric mean fold increase (GMI) of each group after primary immunization.
Time Frame: 30 days
The GMI is the increase of post-immune GMT from pre-immune GMT.
30 days
The incidences of solicited adverse events (AEs) within 7 or 14 days after each dose of each group.
Time Frame: 7 days or 14 days
Solicited AEs occurred within 7 days (for sIPV/wIPV) or 14 days（for bOPV） after each injection will be collected.
7 days or 14 days
Incidence of serious adverse events (SAEs) during the period of safety monitoring.
Time Frame: 30 days.
SAEs during the period of safety monitoring will be collected.
