Group Intervention Description V118C V118C Participants receive intramuscular (IM) injection of V118C in a 2-dose regimen administered on Day 1 and Day 29. V118 V118 Participants receive IM injection of V118 in a 2-dose regimen administered on Day 1 and Day 29. V118 Saline Participants receive IM injection of V118 in a 2-dose regimen administered on Day 1 and Day 29. PREVNAR 20™ + Saline PREVNAR 20™ Participants receive one dose of IM injection of PREVNAR 20™ in a 2-dose regimen on Day 1 followed by one dose of saline on Day 29.

- Primary Outcome Measures
Name Time Method Number of Participants with Solicited Injection Site Adverse Events (AEs) Up to approximately 7 days after each vaccination An AE is defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it is considered related to the medical treatment or procedure, that occurs during the course of the study. The number of participants with a solicited injection-site AE will be reported.
Number of Participants with Solicited Systemic AEs Up to approximately 7 days after each vaccination An AE is defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it is considered related to the medical treatment or procedure, that occurs during the course of the study. The number of participants with a solicited systemic AE will be reported.
Number of Participants with Immediate AEs Following Vaccination Up to approximately 30 minutes after each vaccination An AE is defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it is considered related to the medical treatment or procedure, that occurs during the course of the study. The number of participants with Immediate AEs following vaccination will be reported.
Number of Participants with Unsolicited AEs Up to approximately 28 days after each vaccination An AE is defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it is considered related to the medical treatment or procedure, that occurs during the course of the study. An unsolicited AE is an AE that is not solicited using a vaccine report card (VRC) and that is communicated by a participant. The number of participants that experienced an unsolicited AE will be reported.
Number of Participants With a Serious Adverse Event (SAE) Up to approximately 12 months after final vaccination An SAE is defined as any untoward medical occurrence that at any dose, results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, or is a congenital anomaly/birth defect. The number of participants who experience an SAE will be reported.
Number of Participants with a Medically Attended Adverse Event (MAAE) Up to approximately 12 months after final vaccination An MAAE is defined as an adverse event in which medical attention is received during an unscheduled, non-routine outpatient visit, such as an emergency room visit, office visit, or an urgent care visit with any medical personnel for any reason. The number of participants who experience an MAAE will be reported.
Number of Participants with an Event of Clinical Interest (ECI) Up to approximately 12 months after final vaccination An ECI includes but is not limited to: 1) An overdose defined as: A participant receiving more than 1 dose of study vaccine in a 24-hour period or more than 2 doses of study vaccine throughout the study. 2) Potential drug-induced liver injury (DILI) events defined as: An elevated aspartate aminotransferase (AST) or alanine aminotransferase (ALT) lab value that is ≥3 times the upper limit of normal (ULN) and an elevated total bilirubin lab value that is ≥2 times ULN and, at the same time, an alkaline phosphatase lab value that is \<2 times ULN, as determined by way of protocol-specified laboratory testing or unscheduled laboratory testing. 3) Potential immune-mediated disease (pIMDs) defined as: A subset of AEs that include either an established autoimmune disease(s) or Inflammatory and/or neurologic disorder(s), which might or might not have an autoimmune etiology. The number of participants who experience an ECI will be reported.
- Secondary Outcome Measures
Name Time Method Serotype-specific Immunoglobulin G (IgG) geometric mean concentrations (GMCs) Day 28 postvaccination The GMCs for serotype-specific IgG antibodies will be determined using pneumococcal electrochemiluminescence (Pn ECL) assay.
