结局指标
主要结局
Number of Participants With Elevated Body Temperature (>=37.6 °C Axillary / >=38.0 °C Oral or Equivalent)
时间窗: Up to 5 days postvaccination
Number of Participants Reporting an Injection-site or Systemic Adverse Experience That Was Reported by >=4 Participants
时间窗: Up to Day 14 postvaccination
An adverse experience (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 of a preexisting condition which is temporally associated with the use of the sponsor's product, is also an AE. Injection-site or systemic AEs that occurred in \>=4 participants were reported for this endpoint.
Percentage of Participants With >=2-fold Increase From Prevaccination to Postvaccination in Antibodies to Pneumococcal Serotypes Contained in the Vaccine
时间窗: Day 28 postvaccination
Serum antibodies to pneumococcal serotypes were measured by enzyme-linked immunosorbent assays. A \>=2-fold increase in serum antibody is a marker for serologic response to pneumococcal vaccination in adults.
Number of Participants Reporting Serious Adverse Experiences
时间窗: Up to Day 28 postvaccination
A serious AE (SAE) is an AE that 1) results in death, 2) is life threatening, 3) results in a persistent or significant disability or incapacity, 4) results in or prolongs an existing inpatient hospitalization, 5) is a congenital anomaly or birth defect, 6) is a cancer, 7) is an overdose, or 8) is another important medical event which, based on appropriate medical judgment, may jeopardize the participant and may require medical or surgical intervention
Geometric Mean Concentration of Antibodies to Pneumococcal Serotypes Contained in the Vaccine
时间窗: Prevaccination and Day 28 after vaccination
Serum antibodies to pneumococcal serotypes were measured by enzyme-linked immunosorbent assays
