Group Intervention Description V114 V114 Participants will receive a single 0.5 mL intramuscular (IM) injection of V114 on Day 1. Prevnar 13™ Prevnar 13™ Participants will receive a single 0.5 mL IM injection of Prevnar 13™ on Day 1.
- Primary Outcome Measures
Name Time Method Percentage of Participants With a Vaccine-related Serious Adverse Event Up to 6 months post-vaccination A serious adverse event (SAE) is an AE that results in death, 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. SAEs that were reported by the investigator to be at least possibly related to the study vaccination were summarized.
Geometric Mean Concentration (GMC) of Serotype-specific Immunoglobulin G (IgG) at Day 30 Day 30 The GMC of IgG serotype-specific antibodies to the 13 serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) included in V114 and Prevnar 13™ and 2 serotypes (22F and 33F) unique to V114 were quantitated from participants' sera by a multiplex electrochemiluminescence (ECL) assay.
Percentage of Participants With a Solicited Injection-site Adverse Event Up to 14 days post-vaccination An adverse event (AE) is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. Solicited injection-site AEs included injection-site erythema (redness), injection-site induration (hard lump), injection-site pain (tenderness), and injection-site swelling.
Percentage of Participants With a Solicited Systemic Adverse Event Up to 14 days post-vaccination An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. Solicited systemic AEs included arthralgia (joint pain), fatigue (tiredness), headache, myalgia (muscle pain), and urticaria (hives or welts).
- Secondary Outcome Measures
Name Time Method Geometric Mean Fold Rise (GMFR) in Serotype-specific IgG From Day 1 (Baseline) to Day 30 Day 1 (Baseline) and Day 30 IgG for the 13 serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) included in V114 and Prevnar 13™ and 2 serotypes unique to V114 (22F and 33F) was determined using an electrochemiluminescence assay. GMFR is defined as the geometric mean of the ratio of concentration at Day 30 after vaccination divided by concentration at baseline (Day 1, pre-vaccination).
GMFR in Serotype-specific OPA From Day 1 (Baseline) to Day 30 Day 1 (Baseline) and Day 30 Activity for the 13 serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) included in V114 and Prevnar 13™ and 2 serotypes unique to V114 (22F and 33F) was determined using a MOPA. GMFR is defined as the geometric mean of the ratio of concentration at Day 30 after vaccination divided by concentration at baseline (Day 1, pre-vaccination).
Geometric Mean Titer (GMT) of Serotype-specific Opsonophagocytic Activity (OPA) at Day 30 Day 30 Sera from participants was used to measure 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 2 serotypes (22F and 33F) unique to V114 using the multiplexed opsonophagocytic assay (MOPA).
