Study Overview
Brief Summary
This study is designed to 1) describe the safety, tolerability, and immunogenicity of V114 and Prevnar 13™ in pneumococcal vaccine-naïve adults at increased risk for pneumococcal disease and to 2) describe the safety, tolerability, and immunogenicity of PNEUMOVAX™23 when administered 6 months after receipt of either V114 or Prevnar 13™. Increased risk for pneumococcal disease is defined as 1) an underlying medical condition, 2) behavioral habits such as smoking or alcohol use, or 3) living in a community/environment with increased risk of disease transmission.

Outcomes
Primary Outcomes
Percentage of Participants With a Vaccine-related Serious Adverse Event Following V114 or Prevnar 13™
Time Frame: Up to Month 6 (before Vaccination 2)
A serious adverse event (SAE) is an AE that is life-threatening, requires or prolongs an existing hospitalization, results in persistent or significant disability or incapacity, is a congenital anomaly or birth defect, or is another important medical event deemed such by medical or scientific judgment. Relatedness of an SAE to the study vaccine was determined by the investigator. Following vaccination with V114 or Prevnar 13™, the percentage of serious adverse events of V114 compared with Prevnar 13™ was assessed. Estimated CIs are calculated based on the exact binomial method proposed by Clopper and Pearson.
Percentage of Participants With Solicited Injection-site Adverse Events Following V114 or Prevnar 13™
Time Frame: Up to 5 days after Vaccination 1
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. Following Vaccination 1 with either V114 or Prevnar 13™, the percentage of participants with solicited injection-site AEs was assessed. The solicited injection-site AEs assessed were redness/erythema, swelling, and tenderness/pain. Estimated confidence intervals (CIs) are calculated based on the exact binomial method proposed by Clopper and Pearson.
Percentage of Participants With Solicited Systemic Adverse Events Following V114 or Prevnar 13™
Time Frame: Up to 14 days after Vaccination 1
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. Following vaccination with V114 or Prevnar 13™, the percentage of participants with solicited systemic AEs was assessed. The solicited systemic AEs assessed were muscle pain/myalgia, joint pain/arthralgia, headache, and tiredness/fatigue. Estimated CIs are calculated based on the exact binomial method proposed by Clopper and Pearson.
Geometric Mean Titer of Serotype-specific Opsonophagocytic Activity Day 30 Following V114 or Prevnar 13™
Time Frame: Day 30
The geometric mean titer (GMT) of serotype-specific opsonophagocytic activity (OPA) for the serotypes contained in Prevnar 13™ and V114 (13 serotypes shared with Prevnar 13™ and 2 serotypes unique to V114) was determined using a multiplex opsonophagocytic assay. The within-group 95% CIs are obtained by exponentiating the CIs of the mean of the natural log values based on the t-distribution.
