    The IgG GMCs were evaluated as measured in the Pn ECL assay, for recipients of adjuvanted V114, non-adjuvanted V114, and Prevnar 13® (post-dose 4) for the 13 serotypes in common with PREVNAR 13® (serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, 23F) and the 2 serotypes (serotypes 22F and 33F) not in common with PREVNAR 13®.

  4. Number of Participants With an Adverse Event (AE) [ Time Frame: Up to Day 14 postvaccination ]
    An AE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the Sponsor's product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which is temporally associated with the use of the Sponsor's product, is also an adverse experience.

  5. Number of Participants With an Injection-site AE [ Time Frame: Up to Day 14 postvaccination ]
    Injection-site AEs reported by > 0% of participants in one or more vaccination groups were assessed.

  6. Number of Participants With a Systemic AE [ Time Frame: Up to Day 14 postvaccination ]
    Systemic AEs reported by > 0% of participants in one or more vaccination groups were assessed.

  7. Number of Participants With a Serious Adverse Event (SAE) [ Time Frame: Up to one month after last dose of study vaccine ]
    An SAE is an AE that results in death, is life threatening, requires or prolongs an existing hospitalization, results in persistent or significant disability or incapacity, is a congenital anomaly or birth defect, or is another important medical event deemed such by medical or scientific judgment.

  8. Number of Participants Who Discontinued the Study Due to an AE [ Time Frame: Up to Day 14 postvaccination ]
    An AE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the Sponsor's product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which is temporally associated with the use of the Sponsor's product, is also an adverse experience.


Secondary Outcome Measures :

Functional antibody activity was assessed only in a subset of the vaccinated participants, thus the study was not powered for assessing non-inferiority with respect to the OPA antibody responses.

  2. Percentage of Participants With OPA Titer ≥ 8 as Measured by MOPA4 for Postvaccination 4 [ Time Frame: One month postvaccination 4 ]
    The antibody responses as measured by MOPA4 (post-dose 4) for the 13 serotypes in common with PREVNAR 13® (serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, 23F) and the 2 serotypes (serotypes 22F and 33F) not in common with PREVNAR 13®. Functional antibody activity was assessed only in a subset of the vaccinated participants, thus the study was not powered for assessing non-inferiority with respect to the OPA antibody responses.

  3. OPA Geometric Mean Titers (GMTs) as Measured by MOPA4 for Postvaccination 3 [ Time Frame: One month postvaccination 3 ]
    The antibody responses as measured by MOPA4 (post-dose 3) for the 13 serotypes in common with PREVNAR 13® (serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, 23F) and the 2 serotypes (serotypes 22F and 33F) not in common with PREVNAR 13®. The OPA antibody responses included the percentage of participants with OPA titer and the GMTs.

    The antibody responses as measured by MOPA4 (post-dose 4) for the 13 serotypes in common with PREVNAR 13® (serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, 23F) and the 2 serotypes (serotypes 22F and 33F) not in common with PREVNAR 13®. Functional antibody activity was assessed only in a subset of the vaccinated participants, thus the study was not powered for assessing non-inferiority with respect to the OPA antibody responses.

  6. Percentage of Participants Achieving the IgG Serotype-specific Threshold Value of ≥1.0 μg/mL for Postvaccination 4 [ Time Frame: One month postvaccination 4 ]
    Percentage of participants achieving WHO predefined antibody threshold as measured by the Pn ECL assay corresponding to the WHO enzyme-linked immunosorbent assay (ELISA) value of ≥ 1.0 μg/mL (post-dose 4) for the 13 serotypes in common with PREVNAR 13® (serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, 23F) and the 2 serotypes (serotypes 22F and 33F) not in common with PREVNAR 13®.
