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. Solicited injection-site AEs consist of redness/erythema, swelling, and tenderness/pain. The 95% confidence interval (CI) were based on the exact binomial method proposed by Clopper and Pearson.

All randomized participants who received at least 1 dose of the study vaccination they actually received.

An 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. Solicited systemic AEs consist 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.

All randomized participants who received at least 1 dose of the study vaccination they actually received.

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 is determined by the investigator. The 95% CI were based on the exact binomial method proposed by Clopper and Pearson.

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). This assay reads the reciprocal of the highest dilution (1/dil) that gives ≥50% bacterial killing, as determined by comparison to assay background controls. The 95% CIs were derived by exponentiating the CIs of the mean of the natural log values based on the t-distribution.

All randomized participants without deviations from the protocol that may substantially affect the results of the outcome measure. Deviations include blood draw out of window, prohibited concomitant medication or vaccine, violations of key inclusion/exclusion criteria, or missing serology results.

The geometric mean concentration 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, based on the Meso-Scale Discovery technology, which employs disposable multi-spot microtiter plates. The 95% CIs were derived by exponentiating the CIs of the mean of the natural log values based on the t-distribution.
