Brief Summary:
This a study of V116 in adults ≥50 years of age who concomitantly received Influenza vaccine. The primary objectives of this study are to evaluate the safety, tolerability, and immunogenicity of V116 when administered concomitantly with Quadrivalent Influenza vaccine (QIV) compared with V116 administered sequentially with QIV. The primary hypotheses state that immune responses to V116 and to QIV are non-inferior when administered concomitantly as compared with sequential administration as measured by serotype-specific opsonophagocytic activity (OPA) and hemagglutination inhibition (HAI) geometric mean titers (GMTs) at 30 days postvaccination.

Primary Outcome Measures :
  1. Percentage of Participants with Solicited Injection-site Adverse Events (AEs) [ Time Frame: Up to 5 days post-vaccination ]
    An adverse event (AE) is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The solicited injection-site AEs include tenderness/injection-site pain, injection-site redness/injection-site erythema, and injection-site swelling/injection-site swelling.

  2. Percentage of Participants with Solicited Systemic AEs [ Time Frame: Up to 5 days post-vaccination ]
    An adverse event (AE) is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. The solicited systemic AEs include muscle aches all over body/myalgia, headache, and tiredness/fatigue.

  3. Percentage of Participants with Vaccine-related Serious Adverse Events (SAEs) [ Time Frame: Up to ~210 days ]
    A serious adverse event (SAE) is any untoward medical occurrence that, at any dose, 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 another important medical event. SAEs that were reported to be at least possibly related by the investigator to study vaccination will be summarized.

  4. Geometric Mean Titer of Serotype-specific Opsonophagocytic Activity (OPA) Responses [ Time Frame: 30 days after V116 vaccination (Day 30 for concomitant group and Day 60 for sequential group) ]
    Opsonophagocytic activity (OPA) for the serotypes in V116 will be determined using a multiplexed opsonophagocytic assay (MOPA).

  5. GMT of Influenza Strain-specific Hemagglutination Inhibition (HAI) [ Time Frame: Day 30 ]
    Activity for the 4 strains contained in QIV vaccine will be determined using an HAI assay


Secondary Outcome Measures :
  1. Geometric Mean Concentration (GMC) of Serotype-specific Immunoglobulin G (IgG) [ Time Frame: 30 days after V116 vaccination (Day 30 for concomitant group and Day 60 for sequential group) ]
    The GMC of serotype-specific IgG for the serotypes contained in V116 (serotypes 3, 6A, 7F, 8, 9N, 10A, 11A, 12F, 15A, 15C, 16F, 17F, 19A, 20, 22F, 23A, 23B, 24F, 31, 33F, and 35B) will be determined using an pneumococcal electrochemiluminescence (Pn ECL) assay.

  2. Geometric Mean Fold Rise (GMFR) of Serotype-specific OPA [ Time Frame: Day 1 (Baseline) and Day 30 post-vaccination for concomitant group. Day 1 (Baseline) and Day 60 post-vaccination for sequential group. ]
    Activity for the serotypes contained in V116 (serotypes 3, 6A, 7F, 8, 9N, 10A, 11A, 12F, 15A, 15C, 16F, 17F, 19A, 20, 22F, 23A, 23B, 24F, 31, 33F, and 35B) will be determined using a MOPA. GMFR is defined as the geometric mean of the ratio of concentration at Day 30 after vaccination divided by concentration at baseline.

  3. Geometric Mean Fold Rise (GMFR) of Serotype-specific IgG [ Time Frame: Day 1 (Baseline) and Day 30 post-vaccination for concomitant group. Day 1 (Baseline) and Day 60 post-vaccination for sequential group. ]
    Activity for the serotypes contained in V116 (serotypes 3, 6A, 7F, 8, 9N, 10A, 11A, 12F, 15A, 15C, 16F, 17F, 19A, 20, 22F, 23A, 23B, 24F, 31, 33F, and 35B) will be determined using an Pn ECL assay.

    Activity for the 4 strains contained in QIV vaccine will be determined using an HAI assay. GMFR is GMT 30 days after vaccination / GMT at Baseline.
