Brief Summary:
This is a phase 3, randomized, double-blind, active comparator-controlled study of the safety, tolerability, and immunogenicity of V116 compared to PCV20 (pneumococcal 20-valent conjugate vaccine ([Prevnar 20™ / APEXXNAR™]) in pneumococcal vaccine-naïve adults. It is hypothesized that V116 is noninferior to PCV20 for the common serotypes and superior to PCV20 for the unique serotypes as assessed by serotype-specific opsonophagocytic activity (OPA) 30 days postvaccination. Participants ≥50 years of age will be enrolled in Cohort 1, and participants 18 to 49 years of age will be enrolled in Cohort 2.

Primary Outcome Measures :
  1. Percentage of participants with solicited injection-site AEs [ Time Frame: Up to 5 days postvaccination ]
    An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Solicited injection-site AEs consisted of pain/tenderness, redness/erythema, and swelling.

  2. Percentage of participants with solicited systemic AEs [ Time Frame: Up to 5 days postvaccination ]
    An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Solicited systemic AEs consist of headache, muscle aches/myalgia, and tiredness/fatigue.

  3. Percentage of participants with vaccine-related serious AE (SAE) [ Time Frame: Up to 194 days postvaccination ]
    A vaccine-related SAE is any untoward medical consequence that results in death, is life-threatening, requires inpatient hospitalization or prolongs existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, or is an other important medical event.

  4. Serotype-specific opsonophagocytic (OPA) geometric mean titers (GMTs) in Cohort 1 for the 21 serotypes contained in V116 [ Time Frame: Day 30 postvaccination ]
    The serotype-specific OPA GMTs for the 21 serotypes contained in V116 will be determined using the multiplex opsonophagocytic assay (MOPA).

  5. Percentage of participants with ≥4-fold rise from baseline in serotype-specific OPAs in Cohort 1 for for the 21 serotypes contained in V116 [ Time Frame: Baseline and Day 30 postvaccination ]

  4. Serotype-specific Immunoglobulin G (IgG) geometric mean concentrations (GMCs) in Cohort 1 [ Time Frame: Day 30 postvaccination ]
    The GMCs for serotype-specific IgG antibodies will be determined using pneumococcal electrochemiluminescence (PnECL).

  5. Geometric mean fold rise (GMFR) from baseline in serotype-specific OPA GMTs in Cohort 1 [ Time Frame: Baseline and Day 30 postvaccination ]
