简要总结
The purpose of this study will be to evaluate safety, tolerability and immunogenicity of three lots of 13-valent pneumococcal vaccine given to healthy infants. Lots will be studied for consistency of the immune response, as well as for non-inferiority and safety as compared to 7-valent Pneumococcal Conjugate Vaccine.

主要结局
Geometric Mean Concentration (GMC) for Serotype-specific Pneumococcal Immunoglobulin G (IgG) Antibody in the Three 13vPnC Groups 1 Month After the Infant Series
时间窗: 1 Month after the infant series (7 Months of age)
Antibody geometric mean concentration (GMC) as measured by micrograms per milliliter (mcg/mL) 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. Geometric means (GMs) were calculated using all participants with available data for the specified blood draw.
Percentage of Participants Achieving Predefined Antibody Level ≥1:8 for Poliovirus in the Combined 13vPnC Group Relative to 7vPnC Group 1 Month After the Infant Series
时间窗: 1 month after the infant series (7 months of age)
Percentage of participants achieving predefined antibody threshold ≥1:8 along with the corresponding 95% CI for concomitant antigen poliovirus type 1, type 2, and type 3 (Sabin strains 1, 2, 3) are presented. Exact 2-sided CI was based on the observed proportion of participants. Combined 13vPnC group includes participants randomized to pilot lot 1, pilot lot 2, or the manufacturing lot.
Percentage of Participants Achieving Predefined Antibody Level ≥0.1 International Units Per Milliliter (IU/mL) for Tetanus Toxoid in the Combined 13vPnC Group Relative to 7vPnC Group 1 Month After the Infant Series
时间窗: 1 month after the infant series (7 months of age)
Percentage of participants achieving predefined antibody threshold ≥0.1 IU/ mL along with the corresponding 95% CI for concomitant antigen tetanus toxoid are presented. Exact 2-sided CI was based on the observed proportion of participants. Combined 13vPnC group includes participants randomized to pilot lot 1, pilot lot 2, or the manufacturing lot.
Percentage of Participants Achieving Predefined Antibody Level ≥10.0 Milli-International Units Per Milliliter (mIU/mL) for Hepatitis B in the Combined 13vPnC Group Relative to 7vPnC Group 1 Month After the Infant Series
时间窗: 1 month after the infant series (7 months of age)
Percentage of participants achieving predefined antibody threshold ≥10.0 mIU/ mL along with the corresponding 95% CI for concomitant antigen hepatitis B are presented. Exact 2-sided CI was based on the observed proportion of participants. Combined 13vPnC group includes participants randomized to pilot lot 1, pilot lot 2, or the manufacturing lot.
次要结局
- Percentage of Participants Achieving Serotype-specific Pneumococcal IgG Antibody Level ≥0.35 Mcg/mL in the Three 13vPnC Groups 1 Month After the Infant Series(1 month after the infant series (7 months of age))
- Percentage of Participants Achieving Serotype-specific Pneumococcal IgG Antibody Level ≥0.35 Mcg/mL in the Three 13vPnC Groups 1 Month After the Toddler Dose(1 month after the toddler dose (13 months of age))
- Percentage of Participants Achieving Serotype-specific Pneumococcal IgG Antibody Level ≥1.00 Mcg/mL in the Combined 13vPnC Group 1 Month After the Infant Series(1 month after the infant series (7 months of age))
- Percentage of Participants Achieving Serotype-specific Pneumococcal IgG Antibody Level ≥1.00 Mcg/mL in the Three 13vPnC Groups 1 Month After the Toddler Dose(1 month after the toddler dose (13 months of age))
- Geometric Mean Concentration (GMC) for Serotype-specific Pneumococcal Immunoglobulin G (IgG) Antibody in the Three 13vPnC Groups 1 Month After the Toddler Dose(1 month after the toddler dose (13 months of age))
