主要结局
Percentage of Participants Achieving Predefined Antibody Levels for Diphtheria, Tetanus, Hemophilus Influenza Type b (Hib), Poliomyelitis (Type 1, 2, 3), Pertussis Toxin (PT) and Filamentous Hemagglutinin (FHA) in 13vPnC Group Relative to 7vPnC Group
时间窗: One Month After the 3-Dose Infant Series (at 5 months of age) and the Toddler Dose (at 13 months of age)
Percentage of participants achieving predefined antibody threshold levels ≥0.1 IU/mL for diphtheria, ≥0.1 IU/mL for tetanus, ≥ 0.15 μg/mL for Hib polyribosylribitol phosphate (PRP), antibody titer ≥1:8 for polio and ≥5 EU/mL for pertussis (PT and FHA) with the corresponding 95% CI for each concomitant antigen are presented.
Geometric Mean Concentration (GMC) as Measured by Enzyme-linked Immunosorbent Assay (ELISA) for Diphtheria Toxoid and Tetanus Toxoid in 13vPnC Group Relative to 7vPnC Group
时间窗: One month after the 3-Dose Infant Series (at 5 months of age) and the Toddler Dose (at 13 months of age)
Geometric Mean Concentration (GMC) for Haemophilus Influenzae Type b (Hib) in 13vPnC Group Relative to 7vPnC Group
时间窗: One month after the 3-Dose Infant Series (at 5 months of age) and the Toddler Dose (at 13 months of age)
Geometric Mean Concentration (GMC) as Measured by Enzyme-linked Immunosorbent Assay (ELISA) for Poliomyelitis (Type 1, Type 2 and Type 3) in 13vPnC Group Relative to 7vPnC Group
时间窗: One month after the 3-Dose Infant Series (at 5 months of age) and the Toddler Dose (at 13 months of age)
Geometric Mean Concentration (GMC) as Measured by ELISA for Pertussis Toxin (PT) and Pertussis Filamentous Hemagglutinin (FHA) in 13vPnC Group Relative to 7vPnC Group
时间窗: One month after the 3-Dose Infant Series (at 5 months of age) and the Toddler Dose (at 13 months of age)
Percentage of Participants Achieving a Pneumococcal Antibody Level ≥0.35µg/mL (ELISA) After the 3-Dose Infant Series of 13vPnC
时间窗: 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.
Percentage of Participants Reporting Pre-Specified Local Reactions
时间窗: 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.
Percentage of Participants Reporting Pre-Specified Systemic Events
时间窗: During the 4-day period after each dose
Systemic events (fever \[fv\] ≥ 37.5 degrees Celsius \[C\], fever ≥ 38 C but ≤ 39 C, fever \>39 C but ≤ 40 C, fever \> 40 C, decreased \[decr\] appetite, irritability, increased \[incr\] sleep, decreased sleep, hives, use of medication \[med\] to treat symptoms \[sx\], and use of medication to prevent symptoms) were reported using an electronic diary. Participants may be represented in more than 1 category.
Geometric Mean Concentration (GMC) for Serotype-specific Pneumococcal Immunoglobulin G (IgG) Antibody 1 Month After the 3-Dose Infant Series of 13vPnC
时间窗: One month after the 3-Dose Infant Series (at 5 months of age)
Antibody GMC 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. GMC (13vPnC) and corresponding 2-sided 95% confidence intervals (CI) were evaluated.
