Outcome Measures

Primary Outcomes (3)

  • Percentage of Participants With a Solicited Injection-site Adverse Event (AE)

    An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Solicited injection-site AEs included tenderness/pain, redness/erythema, and swelling. The percentage of participants with one or more solicited injection-site AE was reported for each arm.

    Up to 5 days postvaccination

  • Percentage of Participants With a Solicited Systemic AE

    An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Solicited systemic AEs included headache, muscle pain/myalgia, joint pain/arthralgia, and tiredness/fatigue. The percentage of participants with one or more solicited systemic AE was reported for each arm.

    Up to 5 days postvaccination

  • Percentage of Participants With a Vaccine-related Serious Adverse Event (SAE)

    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. SAEs that were reported by the investigator to be at least possibly related to the study vaccination were reported.

    Up to 62 days postvaccination

Secondary Outcomes (6)

  • Serotype-specific Opsonophagocytic Activity (OPA) Geometric Mean Titers (GMTs) for the Common Serotypes in V116 and PNEUMOVAX™23

    Day 30 postvaccination

  • Serotype-specific Immunoglobulin G (IgG) Geometric Mean Concentrations (GMCs) for the Common Serotypes in V116 and PNEUMOVAX™23

    Day 30 postvaccination

  • Serotype-specific OPA GMTs for the Unique Serotypes in V116

    Day 30 postvaccination

  • Serotype-specific IgG GMCs for the Unique Serotypes in V116

    Day 30 postvaccination

  • Geometric Mean Fold Rise (GMFR) From Baseline in GMTs of Serotype-specific OPA

    Baseline (Day 1) and Day 30 postvaccination

  • +1 more secondary outcomes
