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.

Randomized participants according to the intervention they actually received. One participant randomized to the Prevnar 13™ group incorrectly received V114 Lot 1.

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 consisted of muscle pain/myalgia, joint pain/arthralgia, headache, and tiredness/fatigue. The 95% CI were based on the exact binomial method proposed by Clopper and Pearson.

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.

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.

All randomized participants without deviations from the protocol that may substantially affect the results of the outcome measure. Deviations include randomized but not vaccinated, missing results for serotypes, blood drawn out of time window, prohibited concomitant medication or vaccination.

The geometric mean concentration (GMC) of IgG serotype-specific antibodies to the 13 pneumococcal polysaccharide serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) contained in V114 and Prevnar 13™; and two serotypes (22F and 33F) which are unique to V114, were quantitated from participants' sera by multiplex electrochemiluminescence (ECL) using the pneumococcal electrochemiluminescence (PnECL) v2.0 assay. Per the statistical analysis plan, within-group CIs were not calculated; and the Prevnar 13™ treatment group was not included as it was not analyzed with the same approach as the separate V114 lots.

The Geometric Mean Fold Rise (GMFR) is the geometric mean of the ratio Day 30/Day 1 OPA responses. Per the statistical analysis plan, the Prevnar 13™ treatment group was not analyzed.
