NCT04618640

Brief Summary

The study objective is to assess the immunogenicity and safety of DTaP-IPV combination vaccine administered as a boosting dose to healthy 4 to 6-year-old children who received three doses of primary immunization against diphtheria, tetanus, pertussis, and polio.

Outcome Measures

Primary Outcomes (1)

  • Seroconversion rate after boosting vaccination

    Antibodies will be measured by enzyme-linked immunosorbent assay (ELISA).

    boosting vaccination after Day 28 [+14 days]

Secondary Outcomes (9)

  • Seroprotection rate for anti-DT, anti-TT, and anti-poliovirus or seropositive (>30 IU/mL) rate for anti-PT and anti-FHA before boosting vaccination

    Day 1 Pre-vaccination

  • Minimal seroprotection rate for anti-DT and anti-TT (≥ 0.01 IU/mL) before boosting vaccination

    Day 1 Pre-vaccination

  • Pre-booster antibody level

    Day 1 Pre-vaccination

  • Post-booster antibody level

    boosting vaccination after Day 28 [+14 days]

  • Geometric mean ratio (GMR) between the pre- and post-booster antibody level

    Day 1 Pre-vaccination and boosting vaccination after Day 28 [+14 days]

  • +4 more secondary outcomes

Study Arms (1)

DTaP-IPV combination vaccine

EXPERIMENTAL

DTaP-IPV 0.5ml IM boosting

Biological: DTaP-IPV combination vaccine

Interventions

DTaP-IPV combination vaccine

Eligibility Criteria

Age4 Years - 6 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17)

You may qualify if:

  • A subject's parent/legal representative provides a written consent after being informed about the study objective, methods, effect of the study vaccine, and other relevant information
  • Documented record of the three doses of primary immunization against diphtheria, tetanus, pertussis, and polio either by participating in the previous study, BR-DTPP-CT-301 or by following the national immunization schedule under usual clinical setting (the primary immunization should have been initiated after 6 weeks of age and at minimal interval of 4 weeks)
  • Receipt of a boosting dose against diphtheria, tetanus, and pertussis until 2 years of age; therefore, total of four vaccination records against diphtheria, tetanus, and pertussis and three against polio
  • Healthy male or female children, aged 4 to 6 years on the day of the vaccination

You may not qualify if:

  • Children aged 7 years or older
  • Previously received DTaP vaccine five times or more, including the doses received in the BR-DTPP-CT-301 study, either by a combination vaccine or a separate vaccine
  • Previously received IPV vaccine four times or more, including the doses received in the BR-DTPP-CT-301 study, either by a combination vaccine or a separate vaccine
  • The fourth dose of DTaP vaccine was postponed and administered after 4 years of age
  • Acute febrile illness with fever ≥ 38.0°C (tympanic) on the day of the vaccination
  • Moderate to severe systemic acute illness with or without fever
  • History of diphtheria, tetanus, pertussis, or polio (poliomyelitis)
  • Dysfunctional immune system or congenital or acquired immunodeficiency
  • Had encephalopathy of unknown etiology within 7 days following a previous dose of DTaP vaccine
  • Received a vaccine other than the protocol-permitted vaccines within 28 days from the study vaccination day or are planned to receive such a vaccine during the study period
  • Received systemic corticosteroid treatment at immunosuppressive dosage within 28 days from the study vaccination day or are planned to receive such a treatment during the study period (exceptionally, administration of prednisolone ≤ 0.5 mg/kg/day for up to 14 continuous days is allowed)
  • Received immunoglobulins or blood products within 90 days before the study vaccination day or are planned to receive such products during the study period
  • Had severe allergic reaction (e.g. anaphylaxis) to ingredients of the investigational product or bears such a possibility
  • Currently enrolled in another clinical trial or planned to participate in another clinical trial
  • Any other reasons that preclude the eligibility of the subject, based on investigator's decision
