Primary Outcome Measures:
  • Percentage of Participants Achieving Antibody Level ≥0.35μg/mL in 13vPnC Manufacturing Scale Group Relative to 13vPnC Pilot Scale Group After the 3-Dose Infant Series [ Time Frame: One month after 3-dose infant series (5 months of age) ] [ Designated as safety issue: No ]
    Percentages of participants achieving 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.

  • Percentage of Participants Reporting Pre-Specified Local Reactions [ Time Frame: During the 4-day period after each dose ] [ Designated as safety issue: Yes ]
    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.

  • Percentage of Participants Reporting Pre-Specified Systemic Events (Infant Series) [ Time Frame: During the 4-day period after each dose ] [ Designated as safety issue: Yes ]
    Systemic events (fever ≥ 38 degrees Celsius [C] but ≤ 39 C, fever >39 C but ≤ 40 C, fever > 40 C, decreased appetite, irritability, increased sleep, decreased sleep, use of medication (Meds)to prevent symptoms (sx), and use of medication to treat symptoms) were collected using an electronic diary. Participants may be represented in more than 1 category.

  • Percentage of Participants Reporting Pre-Specified Systemic Events (Toddler Series) [ Time Frame: During the 4-day period after toddler dose ] [ Designated as safety issue: Yes ]
    Systemic events (fever ≥ 38 degrees Celsius [C] but ≤ 39 C, fever >39 C but ≤ 40 C, fever > 40 C), decreased appetite, irritability, increased sleep, decreased sleep, use of medication to prevent symptoms, and use of medication to treat symptoms) were collected using an electronic diary. Participants may be represented in more than 1 category.

  • Geometric Mean Antibody Concentration in 13vPnC Manufacturing Scale Group Relative to 13vPnC Pilot Scale Group After the 3-Dose Infant Series [ Time Frame: One month after 3-dose infant series (5 months of age) ] [ Designated as safety issue: No ]
    Antibody concentration/geometric mean concentration (GMC) as measured by enzyme-linked immunosorbent assay (ELISA) 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.

Criteria

Inclusion criteria:

  1. Aged 2 months (42 to 98 days) at time of enrollment.
  2. Available for entire study period and whose parent/legal guardian can be reached by telephone.
  3. Healthy infant as determined by medical history, physical examination, and judgment of the investigator.
  4. Parent/legal guardian must be able to complete all relevant study procedures during study participation.

Exclusion criteria:

  2. A previous anaphylactic reaction to any vaccine or vaccine-related component.
  3. Contraindication to vaccination with Hib conjugate, diphtheria, tetanus, pertussis, polio, hepatitis B, measles, mumps, rubella, or pneumococcal vaccines.
