Immunogenicity and Safety Evaluation of Bivalent Types 1 and 3 Oral Poliovirus Vaccine by Comparing Different Poliomyelitis Vaccination Schedules in Chinese Infant: a Randomized Controlled Non-Inferiority Clinical Trial
Type 2 component of oral poliovirus vaccine is slated for global withdrawal through a switch from trivalent oral poliovirus vaccine (tOPV) to bivalent oral poliovirus vaccine (bOPV) for preventing paralytic polio caused by circulating vaccine-derived poliovirus type 2. We aimed to assess immunogenicity and safety profile of six vaccination schedules with different sequential doses of inactivated poliovirus vaccine (IPV), tOPV, or bOPV.
Study Overview
Detailed Description
A randomized controlled trial was conducted in China in 2015.
After informed consent was obtained from a parent or legally acceptable representative, healthy newborn babies were randomly allocated to one of six groups: cIPV-bOPV-bOPV, cIPV-tOPV-tOPV, cIPV-cIPV-bOPV, cIPV-cIPV-tOPV, cIPV-cIPV-cIPV, and tOPV-tOPV-tOPV.
The key eligibility criteria were: full-term birth (37-42 weeks of gestation), birthweight ≥2·5 kg, no obvious medical disorders and no polio vaccination.
Infants received following three doses sequentially with 4- 6 weeks interval after collecting blood sample: cIPV-bOPV-bOPV, cIPV-tOPV-tOPV, cIPV-cIPV-bOPV, cIPV-cIPV-tOPV, cIPV-cIPV-cIPV, and tOPV-tOPV-tOPV; and will be proactively followed up for observing adverse events after the first dose and 30 days after all doses.
Antibodies of type 1, 2, and 3 poliovirus were tested 30 days after the third dose.
The primary study objective was to investigate immunogenicity and safety profile of different vaccine schedules, evaluated by seroconversion, seroprotection and antibody titre against poliovirus types 1, 2, and 3 in the per-protocol population.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Proportion of infants with seroconversion
Time Frame: 30 days after vaccination
|
Primary immunogenicity outcome was the proportion of infants with seroconversion, which was defined as the 30 days post-vaccination titer equal or greater than eight for susceptible infants and the post-vaccination titer is four times higher than pre-vaccination titer for unsusceptible infants.
Here, susceptible infants are the ones whose pre-vaccination titer less than eight.
Otherwise, the subjects are categories as unsusceptible ones.
