NCT01577771

Brief Summary

This study aims to evaluate the immunogenicity and reactogenicity of 13-valent pneumococcal conjugate vaccine among infants, toddlers and children in Bobo-Dioulasso, Burkina Faso. Infants will be randomized to receive vaccine at 6, 10, 14 weeks or at 6 weeks, 14 weeks and 9 months of age. Serotype-specific serum IgG, OPA and nasopharyngeal colonization will be assessed at 6 weeks, 18 weeks, 9 months and 10 months of age. Toddlers 12-15 months of age will be randomized to receive either a single dose of PCV13 or 2 doses 2 months apart. Serotype-specific serum IgG and OPA will be measured pre-dose 1 and again 3 months later. Children 2 to 4 years of age will receive a single dose of PCV13 and have IgG and OPA assessments pre-vaccination and 1 month post-vaccination. The immunogenicity and reactogenicity of PCV13 in the "standard schedule" groups (e.g. 6, 10, 14 weeks for infants and single dose for toddlers) will be compared to that observed in the PCV13 licensure trials. Within each age group the alternative schedule will be compared to the standard schedule in terms of immunogenicity and impact on nasopharyngeal carriage (infants only).

Outcome Measures

Primary Outcomes (1)

  • Serotype-specific pneumococcal serum IgG

    Primary outcome in other age groups is: * 3 months post-dose 1 (toddlers) * 1 month post-vaccination (children)

    18 weeks for infants

Secondary Outcomes (4)

  • Serotype-specific pneumococcal serum OPA

    18 weeks, 9 months and 10 months (infants), 3 months post-dose 1 (toddlers), 1 month post-vaccination (children)

  • Vaccine-type and non-vaccine type pneumococcal nasopharyngeal carriage

    18 weeks, 9 months and 10 months (infants)

  • Adverse events following immunization

    1 and 3 days after each dose of vaccine (active surveillance), up to 28 days post-vaccination (passive surveillance)

  • Serotype-specific serum IgG

    in infants, at 9 months and 10 months of age

Study Arms (5)

Child

ACTIVE COMPARATOR

1 dose of Prevnar13 at 2 to 4 years of age

Biological: Prevnar13 (manufactured by Pfizer)

Toddler 1 dose

EXPERIMENTAL

Single dose of Prevnar13 at 12-15 months of age

Biological: Prevnar13 (manufactured by Pfizer)

Toddler 2 dose

ACTIVE COMPARATOR

2 doses of Prevnar13 2 months apart beginning at 12-15 months of age

Biological: Prevnar13 (manufactured by Pfizer)

Infants 2+1

EXPERIMENTAL

Infants receiving Prevnar13 at 6 weeks, 14 weeks and 9 months. Note: This infant immunization schedule is used in many European countries and in South Africa and has been shown to be immunogenic and effective. However, few head-to-head comparisons of the 2+1 and 3+0 schedules have been conducted.
