Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Local Reactions Within 10 Days After Vaccination in All Cohorts
Time Frame: Within 10 days after 20vPnC or 13vPnC
Local reactions were recorded using an electronic diary. Local reactions included redness, swelling and pain at the injection site. Redness and swelling were measured and recorded in measuring device units. 1 measuring device unit =0.5 centimeter (cm). Redness and swelling were graded as mild (greater than [>] 2.0 to 5.0 cm), moderate (>5.0 to 10.0 cm) and severe (>10.0 cm). Pain at injection site was graded as mild (did not interfere with activity), moderate (interfered with activity), and severe (prevented daily activity).
Within 10 days after 20vPnC or 13vPnC
Percentage of Participants With Systemic Events Within 7 Days After Vaccination in All Cohorts
Time Frame: Within 7 days after 20vPnC or 13vPnC
Systemic events fever, fatigue, headache, muscle pain and joint pain were recorded by using an electronic diary. Fever was defined as greater than or equal to (>=) 38.0 degree Celsius (C) and categorized to >=38.0 to 38.4 degree C, >38.4 to 38.9 degree C, >38.9 to 40.0 degree C and >40.0 degree C. Fatigue, headache, muscle pain and joint pain were graded as mild (did not interfere with activity), moderate (some interference with activity) and severe (prevented daily routine activity).
Within 7 days after 20vPnC or 13vPnC
Percentage of Participants With Adverse Events (AEs) Within 1 Month After Vaccination in All Cohorts
Time Frame: Within 1 month after 20vPnC or 13vPnC
An AE was any untoward medical occurrence in study participants who received study vaccine without regard to possibility of causal relationship with the treatment.
Within 1 month after 20vPnC or 13vPnC
Percentage of Participants With Serious Adverse Events (SAEs) Within 6 Months After Vaccination in All Cohorts
Time Frame: Within 6 months after 20vPnC or 13vPnC
An SAE was any untoward medical occurrence at any dose that results in death; is life-threatening (immediate risk of death); requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity (substantial disruption of the ability to conduct normal life functions); results in congenital anomaly/birth defect or that is considered to be an important medical event.
Within 6 months after 20vPnC or 13vPnC
Percentage of Participants With Newly Diagnosed Chronic Medical Conditions (NDCMCs) Within 6 Months After Vaccination in All Cohorts
Time Frame: Within 6 months after 20vPnC or 13vPnC
An NDCMC was defined as a disease or medical condition, not previously identified, that was expected to be persistent or was otherwise long-lasting in its effects.

Time Frame: 1 month after Vaccination 1 in "Cohort 1: 20vPnC/Saline"; 1 month after Vaccination 2 in "Cohort 1: 13vPnC/PPSV23"
OPA GMTs were determined for serotypes: 8, 10A, 11A, 12F, 15B, 22F and 33F. OPA titer was expressed as reciprocal of the highest serum dilution. OPA geometric mean and 2-sided 95% CIs were calculated.

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
