Outcome Measures

Primary Outcomes (2)

  • Anti-Circumsporozoite (Anti-CS) Antibody Concentrations, One Month Post Dose 3 of SB257049 (Primary Analysis)

    Concentrations were expressed as Geometric Mean Concentrations (GMCs) with the following unit of measure: Enzyme Linked Immunosorbent Assay (ELISA) units per milliliter (EU/mL). The 95% confidence intervals were calculated using the Analysis of Variance (ANOVA) model. The antibody response of anti-CS was assessed in the Coad Group and the RTS,S Group.

    At one month post Dose 3 of SB257049 (Month 4)

  • Anti-CS Antibody Concentrations, One Month Post Dose 3 of SB257049 (Study End Analysis)

    Concentrations were expressed as GMCs with the following unit of measure: EU/mL. The 95% confidence intervals were calculated using the ANOVA model. The antibody response of anti-CS was assessed in the Coad Group and the RTS,S Group. The analysis was re-evaluated and performed on the Per-Protocol set for immunogenicity defined at study end.

    At one month post Dose 3 of SB257049 (Month 4)

Secondary Outcomes (37)

  • Anti-CS Antibody Concentrations, Pre-vaccination and One Month Post Dose 3 of SB257049

    At Day 0 and one month post Dose 3 of SB257049 (Month 4)

  • Number of Seropositive Subjects for Anti-CS Antibodies, Pre-vaccination and One Month Post Dose 3 of SB257049

    At Day 0 and one month post Dose 3 of SB257049 (Month 4)

  • Anti-hepatitis B (Anti-HBs) Antibody Concentrations, Pre-vaccination and One Month Post-Dose 3 of SB257049

    At Day 0 and one month post Dose 3 of SB257049 (Month 4)

  • Number of Seroprotected Subjects for Anti-HB Antibodies, Pre-vaccination and One Month Post-Dose 3 of SB257049

    At Day 0 and one month post-Dose 3 of SB257049 (Month 4)

  • Number of Seroconverted Subjects for Anti-Measles (Anti-Me) Antibodies, One Month Post-vaccination With the Combined Measles and Rubella (MeRu) Vaccine

    At one month post-vaccination with the combined measles and rubella (MeRu) vaccine (Month 4)

Coad group

EXPERIMENTAL

Children randomized received Vitamin A at 6 months of age, SB257049 vaccine at 6, 7.5 and 9 months of age, and Yellow Fever (YF) vaccine and a combined measles and rubella vaccine at 9 months of age. Subjects received a booster dose of SB257049 vaccine at 18 months post Dose 3 (i.e. at 27 months of age).

EXPERIMENTAL

Children randomized received Vitamin A at 6 months of age, SB257049 vaccine at 6, 7.5 and 9 months of age, and Yellow Fever (YF) vaccine and a combined measles and rubella vaccine at 10.5 months of age.

EXPERIMENTAL

Children randomized received Vitamin A at 6 months of age and Yellow Fever (YF) vaccine and a combined measles and rubella vaccine at 9 months of age. These children received SB257049 vaccine at 10.5, 11.5 and 12.5 months of age plus a booster dose 17.5 months post Dose 3 (i.e. at 30 months of age).

Eligibility Criteria

Age6 Months - 6 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17)

You may qualify if:

  • Subjects' parent(s)/Legally Acceptable Representative(s) (LAR\[s\]) who, in the opinion of the investigator, could and complied with the requirements of the protocol.
  • A male or female 6 months of age (from the day the child becomes 6 months of age until the day before the child achieved 7 months of age) at the time of the first vaccination.
  • Signed or thumb-printed informed consent obtained from the parent(s)/LAR(s) of the subject. Where parent(s)/LAR(s) were illiterate, the consent form was countersigned by an independent witness.
  • Healthy subjects as established by medical history and clinical examination before entering into the study.
  • Previously received three documented doses of diphtheria, tetanus, and whole-cell pertussis, hepatitis B vaccine (DTPwHepB), and a 3-dose course of oral polio vaccine and, if locally recommended, pneumococcal and rotavirus vaccines.

You may not qualify if:

  • Child in care
  • Use of a drug or vaccine that is not approved for that indication other than the study vaccines within 30 days preceding the first dose of study vaccine, or planned use during the study period.
  • Any medical condition that in the judgment of the investigator would make intramuscular injection unsafe.
  • Chronic administration of immunosuppressants or other immune-modifying drugs within six months prior to the first vaccine dose. For corticosteroids, this meant prednisone≥ 0.5 mg/kg/day, or equivalent. Inhaled and topical steroids were allowed.
  • Planned administration/administration of a vaccine not foreseen by the study protocol in the period starting seven days before the first dose of SB257049 measles, rubella and YF vaccines and ending 42 days after the last dose of vaccines given at 9 months of age (Visit 4), with the exception of oral polio vaccine which could be given for unforeseen public health threat.
  • 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 vaccine/product.
  • Previous vaccination against measles, YF or rubella.
  • Previous administration of Vitamin A.
  • Moderate or severe malnutrition at screening defined as weight for age Z-score \< -2.
  • Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination.
  • Family history of congenital or hereditary immunodeficiency.
  • History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccine(s). See also Section 1.3.
  • Major congenital defects or serious chronic illness.
  • History of any neurological disorders or seizures.
  • Acute disease and/or fever at the time of enrolment. Fever was defined as temperature ≥ 37.5°C /99.5°F for oral, axillary or tympanic route, or ≥ 38.0°C /100.4°F on rectal route. The preferred route for recording temperature in this study was axillary.
