Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Adverse Events (AEs) Within 1 Month After Vaccination in All CohortsWithin 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.

Percentage of Participants With Local Reactions Within 10 Days After Vaccination in All CohortsWithin 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).

Percentage of Participants With Systemic Events Within 7 Days After Vaccination in All CohortsWithin 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).

Percentage of Participants With Serious Adverse Events (SAEs) Within 6 Months After Vaccination in All CohortsWithin 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.

Percentage of Participants With Newly Diagnosed Chronic Medical Conditions (NDCMCs) Within 6 Months After Vaccination in All CohortsWithin 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.
