Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Solicited Systemic AEs From Day 1 Through Day 5 Postvaccination in Part AUp to 5 days after each vaccination in Part A

An adverse event (AE) is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The percentage of participants with solicited systemic AEs was assessed following any vaccination. The solicited systemic AEs assessed were fatigue, headache, myalgia, and pyrexia.

Percentage of Participants With Solicited Injection-site AEs From Day 1 Through Day 5 Postvaccination in Part AUp to 5 days after each vaccination in Part A

An adverse event (AE) is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The percentage of participants with solicited injection-site AEs after any vaccination was assessed. The solicited injection-site AEs assessed were redness/erythema, swelling, and tenderness/pain.

Percentage of Participants With Vaccine-related Serious Adverse Events (SAEs) From Day 1 Through the Duration of Participation in Part AUp to 194 days in Part A

A serious adverse event (SAE) is an AE that 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. Relatedness of an SAE to the study vaccine was determined by the investigator. Following any vaccination, the percentage of serious adverse events was assessed.

Serotype-specific Opsonophagocytic Activity (OPA) Geometric Mean Titers (GMT) Postvaccination in Part A for 13 Serotypes Common Between V116 and PCV15 + PPSV23 and 8 Serotypes Unique to V116Up to 114 days

Serotype-specific OPA to the 13 serotypes common between V116 and PCV15 + PPSV23 and 8 serotypes unique to V116 were determined using a multiplex opsonophagocytic assay (MOPA). GMT is defined as geometric mean titer (1/dil). Serotype-specific OPA GMTs with 95% confidence intervals are presented.
