Brief summary

The purpose of this study is to assess the safety, tolerability and immunogenicity of a 13-valent pneumococcal conjugate (13vPnC) vaccine compared to 7-valent pneumococcal conjugate (Prevenar/Prevenar®, 7vPnC), when given concomitantly with Infanrix hexa at 2, 3, 4, months (infant series) and at 11-12 months of age (toddler dose) in Germany.

Geometric Mean Concentration in 13vPnC Group Relative to 7vPnC Group Before and After the Toddler Dose

Antibody concentration/geometric mean concentration as measured by ELISA with their corresponding 95% CI immediately before and after the toddler dose for 7 common pneumococcal serotypes (Serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F) and 6 additional pneumococcal serotypes specific to 13vPnC (Serotypes 1, 3, 5, 6A, 7F, and 19A) are presented.

Time frame: Immediately before (12 months of age) and one month after the toddler dose (13 months of age)

Population: Evaluable immunogenicity (per protocol) population of eligible participants who adhered to protocol requirements, had valid and determinate assay results, and had no other major protocol violations; (n)= number of participants with a determinate antibody concentration for the specified concomitant antigen.

Percentage of Participants Reporting Pre-Specified Local Reactions

Local reactions were reported using an electronic diary. Tenderness was scaled as Any (tenderness present); Significant (Sig) (present and interfered with limb movement). Induration and erythema were scaled as Any (induration or erythema present); Mild (0.5 centimeters \[cm\] to 2.0 cm); Moderate (Mod)(2.5 to 7.0 cm); Severe (\> 7.0 cm). Participants may be represented in more than 1 category.

Time frame: Day 1 through 4 after each dose

Population: Safety population, included participants who received given dose; (n) = number of participants reporting the specific characteristic.

Primary

Percentage of Participants Reporting Pre-Specified Systemic Events (Toddler Series)

Systemic events (any fever ≥ 38 degrees Celsius \[C\], decreased appetite, irritability, increased sleep, decreased sleep, and hives \[urticaria\]) were reported using an electronic diary. Participants may be represented in more than 1 category.

Time frame: Day 1 through 4 after each dose

Population: Safety population, participants who received given dose; (n)= number of participants reporting yes for at least 1 day or no for all days.
