Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Newly Diagnosed Chronic Medical Conditions (NDCMCs) Within 6 Months After VaccinationWithin 6 months after vaccination

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.

Percentage of Participants With Systemic Events Within 7 Days After VaccinationWithin 7 days after vaccination

Systemic events fever, fatigue, headache, muscle pain and joint pain were recorded by using an e-diary. Fever was defined as temperature \>=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 Adverse Events (AEs) Within 1 Month After VaccinationWithin 1 month after vaccination

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 Serious Adverse Events (SAEs) Within 6 Months After VaccinationWithin 6 months after vaccination

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 Local Reactions Within 10 Days After VaccinationWithin 10 days after vaccination

Local reactions were recorded using an electronic diary (e-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).

Pneumococcal Opsonophagocytic Activity (OPA) Geometric Mean Titers (GMTs) at 1 Month After Vaccination1 month after vaccination

OPA GMTs were determined for serotypes: 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, 23F, 8, 10A, 11A, 12F, 15B, 22F and 33F. OPA titer was expressed as reciprocal of the highest serum dilution.

Secondary Outcome Measures
NameTimeMethod
Pneumococcal OPA Geometric Mean Fold Rise (GMFR) From Before Vaccination to 1 Month After VaccinationFrom before vaccination to 1 month after vaccination

OPA GMFR is the ratio of OPA GMTs, 1 month after vaccination to before vaccination. OPA GMFRs from before to 1 month after vaccination were calculated for pneumococcal serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, 23F, 8, 10A, 11A, 12F, 15B, 22F and 33F.

Percentage of Participants With >=4-Fold Rise in Pneumococcal OPA Titers From Before Vaccination to 1 Month After VaccinationFrom before vaccination to 1 month after vaccination

Percentage of participants with a \>=4-fold rise in pneumococcal OPA titers from before vaccination to 1 month after vaccination were calculated for pneumococcal serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, 23F, 8, 10A, 11A, 12F, 15B, 22F and 33F.

Percentage of Participants With Pneumococcal OPA Titers >=Lower Limit of Quantitation (LLOQ) at 1 Month After Vaccination1 month after vaccination

The percentage of participants with OPA titers \>=LLOQ at 1 month after vaccination were calculated for pneumococcal serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, 23F, 8, 10A, 11A, 12F, 15B, 22F and 33F.
