The primary objectives are to evaluate the safety and tolerability of V114 and to compare the serotype-specific opsonophagocytic activity (OPA) geometric mean titers (GMTs) across 3 different lots of V114. The primary hypothesis is that all 3 lots of V114 are equivalent as measured by the serotype-specific OPA GMTs for 15 serotypes in V114 at 30 days postvaccination.

Percentage of Participants With a Solicited Injection-site Adverse Event Following Vaccination With Separate V114 Lots
An adverse event (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 redness/erythema, swelling, and tenderness/pain. The 95% confidence interval (CI) were based on the exact binomial method proposed by Clopper and Pearson. Following vaccination with the three lots of V114 the percentage of participants with solicited injection-site AEs was assessed. Per the statistical analysis plan, the Prevnar 13™ treatment group was not included as it was not analyzed with the same approach as the separate V114 lots.
Time frame: Up to Day 5

Percentage of Participants With a Vaccine-related Serious Adverse Event Following Vaccination With Separate V114 Lots
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. Relatedness of an SAE to the study vaccine is determined by the investigator. The 95% CI were based on the exact binomial method proposed by Clopper and Pearson. Following vaccination with the three lots of V114 the percentage of participants with SAEs was assessed. Per the statistical analysis plan, the Prevnar 13™ treatment group was not included as it was not analyzed with the same approach as the separate V114 lots.

Geometric Mean Titer of Serotype-specific Opsonophagocytic Activity (OPA) Following Vaccination With Separate V114 Lots
Opsonization of pneumococci for phagocytosis is an important mechanism by which antibodies to polysaccharides protect against disease in vivo. Sera from participants was used to measure geometric mean titer (GMT) of 13 serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) included in V114 and Prevnar 13™; and two serotypes (22F and 33F) which are unique to V114, using the Multiplexed Opsonophagocytic Assay (MOPA). Per the statistical analysis plan, within-group CIs were not calculated. 95% CIs were calculated for the GMT ratios between pairs of V114 lots by a constrained longitudinal data analysis (cLDA) model; and the Prevnar 13™ treatment group was not included as it was not analyzed with the same approach as the separate V114 lots.
Time frame: Day 30
