Brief Summary:
This is a Phase 2, randomized, double-blinded study with a 2-arm parallel design. Healthy adults aged 60 through 64 years of age with no history of pneumococcal vaccination will be randomized equally to receive either a single intramuscular dose of multivalent pneumococcal conjugate vaccine followed 1 month later with a dose of saline or Prevnar 13 followed 1 month later with a dose of PPSV23 (control group).

Primary Outcome Measures :
  1. Percentage of Participants With Local Reactions Within 10 Days After Vaccination 1 [ Time Frame: within 10 days after Vaccination 1 ]
    Local reactions included pain at injection site, swelling and redness recorded by participants in an electronic diary (e-diary). 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 centimeter (cm), moderate: 5.5 to 10.0 cm and severe: greater than or equal to (>=) 10.5 cm. Pain was graded as mild: did not interfere with activity, moderate: interfered with activity and severe: prevented daily activity.

  2. Percentage of Participants With Systemic Events Within 7 Days After Vaccination 1 [ Time Frame: within 7 days after Vaccination 1 ]
    Systemic events included fever, fatigue, headache, muscle pain and joint pain, recorded by participants in an e-diary. Fever was categorized as: >=38.0 degrees Celsius (C), >=38.0 to 38.4 degrees C, >38.4 to 38.9 degrees C, >38.9 to 40.0 degrees C and >40.0 degrees C. Fatigue, headache, muscle pain and joint pain were graded as mild: no interference with activity, moderate: some interference with activity and severe: prevents daily routine activity.

  3. Percentage of Participants With Adverse Events (AEs) Within 1 Month After Vaccination 1 [ Time Frame: within 1 month after Vaccination 1 (up to 35 days) ]
    An AE was any untoward medical occurrence in a participant who received investigational product without regard to possibility of causal relationship. AEs included both serious and non-serious adverse events. Serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.

  4. Percentage of Participants With Serious Adverse Events (SAEs) or Newly Diagnosed Chronic Medical Conditions (NDCMCs) Within 6 Months After Vaccination 1 [ Time Frame: within 6 months after Vaccination 1 (up to 196 days) ]
    An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. An NDCMC was defined as a disease or medical condition, not previously identified, that is expected to be persistent or is otherwise long-lasting in its effects. Percentage of participants with either SAE or NDCMCs during the specified duration are reported.

  5. Percentage of Participants With Serious Adverse Events (SAEs) or Newly Diagnosed Chronic Medical Conditions (NDCMCs) Within 12 Months After Vaccination 1 [ Time Frame: within 12 months after Vaccination 1 (up to 378 days) ]
    An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. An NDCMC was defined as a disease or medical condition, not previously identified, that is expected to be persistent or is otherwise long-lasting in its effects. Percentage of participants with either SAE or NDCMCs during the specified duration are reported.


Secondary Outcome Measures :
  1. Serotype-Specific Pneumococcal Opsonophagocytic Activity (OPA) Geometric Mean Titres (GMTs) 1 Month After Vaccination 1: 13 Common Serotypes in 13vPnC [ Time Frame: 1 month after Vaccination 1 ]
    Antibody-mediated serum OPA against the 13 common pneumococcal serotypes specific to 13vPnC (serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F and 23F) were measured using a pneumococcal OPA assay. Results were expressed as OPA GMTs. Assay results below the lower limit of quantitation (LLOQ) were set to 0.5*LLOQ in the analysis.

  2. Serotype-Specific Pneumococcal Opsonophagocytic Activity (OPA) Geometric Mean Titres (GMTs) 1 Month After Any Vaccination: 7 Additional Serotypes in 20vPnC [ Time Frame: 1 month after Vaccination 1 for 20vPnC followed by saline reporting group; 1 month after Vaccination 2 for 13vPnC followed by PPSV23 reporting group ]
    Antibody-mediated serum OPA against the 7 additional pneumococcal serotypes (8, 10A, 11A, 12F, 15B, 22F, 33F) were measured using a pneumococcal OPA assay. Results were expressed as OPA GMTs. Assay results below the LLOQ were set to 0.5*LLOQ in the analysis.

  3. Serotype-specific Pneumococcal Opsonophagocytic Activity (OPA) Geometric Mean Fold Rise (GMFR) From Pre-Vaccination 1 to 1 Month Post-Vaccination 1: 13 Common Serotypes in 13vPnC [ Time Frame: before Vaccination 1 to one month after Vaccination 1 ]
    GMFR for the 13 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) from before Vaccination 1 to one month after Vaccination 1 were calculated as the mean of the difference of logarithmically transformed OPA results (after vaccination - before vaccination) and transform back to the original scale. GMFRs were calculated using data from participants with non-missing OPA results at both time points. Assay results below the LLOQ were set to 0.5*LLOQ in the analysis.

  4. Serotype-specific Pneumococcal Opsonophagocytic Activity (OPA) Geometric Mean Fold Rise (GMFR) From Pre-Vaccination 1 to 1 Month Post Any Vaccination: 7 Additional Serotypes in 20vPnC [ Time Frame: before Vaccination 1 to 1 month after Vaccination 1 for 20vPnC followed by saline reporting group; before Vaccination 1 to 1 month after Vaccination 2 for 13vPnC followed by PPSV23 reporting group ]
    GMFR for 7 additional pneumococcal serotypes (8, 10A, 11A, 12F, 15B, 22F, 33F) from before Vaccination 1 to one month after either Vaccination 1 (20vPnC) or Vaccination 2 (PPSV23) were calculated as the mean of the difference of logarithmically transformed OPA results (after vaccination - before vaccination) and transform back to the original scale. GMFRs were calculated using data from participants with non-missing OPA results at both time points. Assay results below the LLOQ were set to 0.5*LLOQ in the analysis.
