结局指标

主要结局

Percentage of Participants With a Solicited Systemic AE

时间窗: Up to 5 days postvaccination

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.

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

时间窗: Up to 5 days postvaccination

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.

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

时间窗: Up to 62 days postvaccination

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.

次要结局

  • Serotype-specific OPA GMTs 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)
  • Serotype-specific Opsonophagocytic Activity (OPA) Geometric Mean Titers (GMTs) for the Common Serotypes in V116 and PNEUMOVAX™23(Day 30 postvaccination)
  • GMFR From Baseline in Serotype-specific IgG GMCs(Baseline (Day 1) and 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 IgG GMCs for the Unique Serotypes in V116(Day 30 postvaccination)
