Overview
Brief Summary
The purpose of the study is to compare the immunogenicity and safety of a booster dose of BoostrixTM Polio to that of Sanofi Pasteur MSD's RepevaxTM, when co-administered with a second dose of PriorixTM, in healthy 3 and 4-year-old children.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Subjects who the investigator believes that their parent(s)/Legally Acceptable Representative(s) (LAR) can and will comply with the requirements of the protocol should be enrolled in the study.
- •A male or female child of 3 or 4 years of age at the time of booster vaccination (up to, but excluding 5 years of age).
- •Subjects who have received a complete three-dose primary vaccination with diphtheria-tetanus-acellular pertussis (DTPa) vaccine and inactivated poliovirus (IPV) vaccine in the first six months of life, in line with recommendations in the United Kingdom (UK).
- •Subjects who received a first dose of a live attenuated measles-mumps-rubella vaccine within the second year of life, in line with recommendations in the UK.
- •Written informed consent obtained from the parent(s)/LAR(s) of the subject at the time of enrolment.
- •Healthy subjects as established by medical history and clinical examination before entering into the study.
Exclusion Criteria
- •Child in care.
- •Use of any investigational or non-registered product other than the study vaccine(s) within 30 days preceding the booster dose of study vaccine, or planned use during the study period.
- •Chronic administration of immunosuppressants or other immune-modifying drugs within six months prior to the booster vaccine dose.
- •Administration of a vaccine not foreseen by the study protocol within 30 days prior to vaccination, or planned administration during the study period, with the exception of inactivated influenza vaccine.
- •Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational product.
- •Previous booster vaccination against diphtheria, tetanus, pertussis, poliomyelitis since primary vaccination in the first year of life.
- •Previous measles, mumps and/or rubella second dose vaccination.
- •Evidence of previous or intercurrent diphtheria, tetanus, pertussis, poliomyelitis, measles, mumps and/or rubella disease.
- •Known exposure to measles, mumps and/or rubella within 30 days prior to study start.
- •Any confirmed or suspected immunosuppressive or immunodeficiency condition, based on medical history and physical examination.
Outcomes
Primary Outcomes
Number of Subjects With a Booster Response to Diphtheria (D) and Tetanus (T) Antigens
Time Frame: At Month 1, one month after the booster vaccination
Booster response was defined as: For initially seronegative subjects \[i.e. pre-vaccination concentration below (\<) cut-off value of 0.1 international units per milliliter (IU/mL)\] antibody concentrations at least four times the assay cut-off \[post vaccination concentration greater than or equal to (≥) 0.4 IU/ml\]. For initially seropositive subjects (pre-vaccination concentration ≥ 0.1 IU/ml), an increase in antibody concentrations of at least four times the Pre booster vaccination concentration.
Anti-pertussis Toxoid (Anti-PT), Anti-filamentous Haemagglutinin (Anti-FHA) and Anti-pertactin (Anti-PRN) Antibody Concentrations
Time Frame: At Month 1, one month after the booster vaccination
Antibody concentrations were presented as geometric mean concentrations (GMCs), expressed in enzyme-linked immunosorbent assay (ELISA) units per milliliter (EL.U/mL).
Anti-Polio Virus Type 1, 2 and 3 Antibody Titers
Time Frame: At Month 1, one month after the booster vaccination
Antibody titers were presented as geometric mean titers (GMTs).
