NCT06920069

Brief Summary

This study is a randomized, open-labeled phase IV clinical trial to evaluate the immunogenicity and safety of concomitant administration of sIPV and DTaP or MMR in infants aged 2 months. Primary immunogenicity endpoints in all groups include the seroconversion rate of type I, II, and III anti-poliovirus neutralizing antibodies, anti-DT, anti-TT, anti-PT, anti-FHA, and anti-PRN antibodies 30 days after basic immunization. Secondary immunogenicity endpoints include the seropositive rates, seroconversion rates, geometric mean titer/concentration (GMT/GMC), geometric mean fold increase (GMFI) of type I, II, and III anti-poliovirus neutralizing antibodies, anti-DT, anti-TT, anti-PT, anti-FHA, and anti-PRN antibodies, and anti-measles, anti-mumps, and anti-rubella antibodies 30 days after full immunization. The secondary safety endpoints are the incidence of adverse events (AEs) within 30 minutes after each injection, the incidence of solicited local and systematic AEs in the period of solicitation after each injection, the incidence of unsolicited AEs in 30 days after each injection, the incidence of AEs in 30 days after each injection, and the incidence of serious adverse events in 6 months after administrations.

Outcome Measures

Primary Outcomes (7)

  • Immunogenicity index-seroconversion rate of type I anti-poliovirus neutrilizing antibody

    Neutralizing antibody assay will be performed using the neutralization method. Seroconversion will be defined as a change from seronegative (\<1:8) to seropositive (≥1:8), or a ≥4-fold increase from baseline

    Between baseline and day 30 after basic vaccination

  • Immunogenicity index-seroconversion rate of type II anti-poliovirus neutrilizing antibody

    Neutralizing antibody assay will be performed using the neutralization method. Seroconversion will be defined as a change from seronegative (\<1:8) to seropositive (≥1:8), or a ≥4-fold increase from baseline

    Between baseline and day 30 after basic vaccination

  • Immunogenicity index-seroconversion rate of type III anti-poliovirus neutrilizing antibody

    Neutralizing antibody assay will be performed using the neutralization method. Seroconversion will be defined as a change from seronegative (\<1:8) to seropositive (≥1:8), or a ≥4-fold increase from baseline

    Between baseline and day 30 after basic vaccination

  • Immunogenicity index-seroconversion rate of anti-DT antibody

    Antibody assay will be performed using the ELISA method. Seroconversion will be defined as a change from seronegative (Antibody Concentration\<0.1 IU/ml) to seropositive (Antibody Concentration≥0.1 IU/ml), or a ≥4-fold increase from baseline.

    Between baseline and day 30 after basic vaccination

  • Immunogenicity index-seroconversion rate of anti-TT antibody

    Antibody assay will be performed using the ELISA method. Seroconversion will be defined as a change from seronegative (Antibody Concentration\<0.1 IU/ml) to seropositive (Antibody Concentration≥0.1 IU/ml), or a ≥4-fold increase from baseline.

    Between baseline and day 30 after basic vaccination

  • Immunogenicity index-seroconversion rate of anti-PT antibody

    Antibody assay will be performed using the ELISA method. Seroconversion will be defined as a change from seronegative (Antibody Concentration\<20 IU/ml) to seropositive (Antibody Concentration≥20 IU/ml), or a ≥4-fold increase from baseline.

    Between baseline and day 30 after basic vaccination

  • Immunogenicity index-seroconversion rate of anti-FHA antibody

    Antibody assay will be performed using the ELISA method. Seroconversion will be defined as a change from seronegative (Antibody Concentration\<20 IU/ml) to seropositive (Antibody Concentration≥20 IU/ml), or a ≥4-fold increase from baseline.

    Between baseline and day 30 after basic vaccination
