Biological: 13-valent Pneumococcal Conjugate Vaccine
- Percentage of Participants Achieving Antibody Level ≥0.35μg/mL After Vaccination [ Time Frame: 28 to 42 days after vaccination 3 for Group 1 (13 to <17 months of age), after vaccination 2 for Group 2 (14 to <26 months of age), and after vaccination 1 for Group 3 (26 to <73 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.
- Geometric Mean Antibody Concentration (GMC) After Vaccination in 13vPnC Groups [ Time Frame: 28 to 42 days after vaccination 3 for Group 1 (13 to <17 months of age), after vaccination 2 for Group 2 (14 to <26 months of age), and after vaccination 1 for Group 3 (26 to <73 months of age). ]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.
- 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 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 (>7.0 cm). Participants may be represented in more than 1 category.
- Percentage of Participants Reporting Pre-Specified Systemic Events [ Time Frame: During the 4-day period after each dose ]Systemic events (fever ≥ 37.5 degrees Celsius [C], fever ≥ 38 C but ≤ 39 C, fever >39 C but ≤ 40 C, fever > 40 C, decreased appetite, irritability, increased sleep, decreased sleep, hives, use of medication to treat symptoms, and use of medication to prevent symptoms) were reported using an electronic diary. Participants may be represented in more than 1 category.
