    Time frame: One month after the 3-Dose Infant Series (at 5 months of age) and the Toddler Dose (at 13 months of age)

  5. Geometric Mean Concentration (GMC) as Measured by ELISA for Pertussis Toxin (PT) and Pertussis Filamentous Hemagglutinin (FHA) in 13vPnC Group Relative to 7vPnC Group

    Time frame: One month after the 3-Dose Infant Series (at 5 months of age) and the Toddler Dose (at 13 months of age)

  6. Percentage of Participants Achieving a Pneumococcal Antibody Level ≥0.35µg/mL (ELISA) After the 3-Dose Infant Series of 13vPnC

    Time frame: One month after the 3-Dose Infant Series (at 5 months of age)

    Percentages of participants achieving World Health Organization (WHO) predefined antibody threshold ≥0.35μg/mL along with the corresponding 95% CI for the 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.

  7. Percentage of Participants Reporting Pre-Specified Local Reactions

    Time frame: During the 4-day period after each dose

    Local reactions were collected using an electronic diary. Tenderness (Tender)was scaled as Any (tenderness present); Significant (present and interfered with limb movement). Swelling and redness were scaled as Any (swelling or redness present); Mild (0.5 centimeters [cm] to 2.0 cm); Moderate (2.5 to 7.0 cm); Severe (Sev) (>7.0 cm). Participants may be represented in more than 1 category.
