1.Primary Outcome
Title Adult and Toddler Subjects Experiencing Local and Systemic Reactogenicity, by Severity
Hide Description

Local and systemic reactogenicity of the study vaccine was evaluated for severity by toxicity grading scale (0 [none], 1 [mild], 2 [moderate], 3 [severe], 4 [potentially life threatening]) and relatedness to the vaccination. Injection site events were by definition considered related to study vaccine. Reactogenicity was monitored at the following times:

  • At 60 (± 15) minutes following primary vaccination
  • Daily by field workers during Days 1 to 6 post vaccination
  • In the clinic on Day 7 (+3) following each vaccination (Visit 2 for adults and toddlers).
Time Frame 7 days

3.Primary Outcome
Title Infant Subjects Experiencing Local and Systemic Reactogenicity, by Severity: Vaccination 2
Hide Description

Local and systemic reactogenicity of the study vaccine was evaluated for severity by toxicity grading scale (0 [none], 1 [mild], 2 [moderate], 3 [severe], 4 [potentially life threatening]) and relatedness to the vaccination. Injection site events were by definition considered related to study vaccine. Reactogenicity was monitored at the following times:

  • At 60 (± 15) minutes following primary vaccination
  • Daily by field workers during Days 1 to 6 post vaccination
  • In the clinic on 7 days (+3) following each vaccination (Visit 2, 4, and 6 for infants).

Title Occurrence, Severity and Relatedness of Clinically Significant Hematological and Biochemistry Lab Values in Adults and Toddlers
Hide Description Blood samples were collected for safety hematology and clinical chemistry evaluations, organ function tests, and, for adults, coagulation panel evaluation. Laboratory assessments were only performed at baseline for infants. Testing for HIV was undertaken only following pre-test counseling of the subject/subject’s parent as to the implications of the test result. Post test counseling was also undertaken, and on the basis of a positive result the subject and subject’s parents would have been referred on for HIV care according to normal local practice in The Gambia.

Title Geometric Mean Fold Rise (GMFR) of Immunoglobulin G (IgG) in Toddlers, by Serotype
Hide Description Serum samples were collected before the first vaccination and 28 days after the last vaccination for adults and toddlers and 28 days after the completion of the primary series for infants to determine the ELISA IgG concentration for all 10 serotypes contained in SIILPCV10. Blood samples were also collected for immunogenicity testing before and 28 days after the booster dose for infants. Baseline serum samples for infants and adults were not assayed. The IgG concentration was also determined for each component of the co administered pentavalent vaccine (DTwP-HepB-Hib) in sera from the infant cohort. If there were limitations to blood volumes, appropriate subsets and priorities for immune testing were established with the immunology laboratories to ensure measurements were unbiased and representative of the entire cohort.

Comments Treatment group differences were estimated by the difference in proportion of seroresponders, with 2-sided exact 90% CIs around the difference calculated using the unconditional exact method of Newcombe. Although inference regarding seroresponse was not of primary concern in this study, a 2-sided 90% CI that excluded 0 was indicative of statistically significant difference at p ≤ 0.10 not corrected for multiplicity analysis.

13.Secondary Outcome
Title Functional Antibody (OPA) Geometric Mean Titers
Hide Description The functional activity of the IgG response to the 10 serotypes contained in SIILPCV10 was determined in randomly selected subsets of the infant and toddler cohorts and all adult subjects in the same serum samples collected 28 days after the last vaccinations. This activity was determined using the 4-fold multiplexed OPA developed at the University of Alabama at Birmingham.
