Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Child

1 dose of Prevnar13 at 2 to 4 years of age

Group Type ACTIVE_COMPARATOR

Prevnar13 (manufactured by Pfizer)

Intervention Type BIOLOGICAL

Prevnar13 administered IM in the antero-lateral thigh

Toddler 1 dose

Single dose of Prevnar13 at 12-15 months of age

Group Type EXPERIMENTAL

Prevnar13 (manufactured by Pfizer)

Intervention Type BIOLOGICAL

Prevnar13 administered IM in the antero-lateral thigh

Toddler 2 dose

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

Group Type ACTIVE_COMPARATOR

Prevnar13 (manufactured by Pfizer)

Intervention Type BIOLOGICAL

Prevnar13 administered IM in the antero-lateral thigh

Infants 2+1

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.

Group Type EXPERIMENTAL

Intervention Type BIOLOGICAL

Prevnar13 administered IM in the antero-lateral thigh

Infants 3+0

Infants receiving Prevnar13 at 6, 10 and 14 weeks

Group Type ACTIVE_COMPARATOR

Prevnar13 (manufactured by Pfizer)
