Foranstaltningsbeskrivelse
Tidsramme
Percentage of Participants With a Solicited Injection-site Adverse Event
Tidsramme: 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.
Up to 14 days post-vaccination
Percentage of Participants With a Solicited Systemic Adverse Event
Tidsramme: 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).
Up to 14 days post-vaccination
Percentage of Participants With a Vaccine-related Serious Adverse Event
Tidsramme: 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.
Up to 6 months post-vaccination
Geometric Mean Concentration (GMC) of Serotype-specific Immunoglobulin G (IgG) at Day 30
Tidsramme: 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.

Tidsramme
Geometric Mean Titer (GMT) of Serotype-specific Opsonophagocytic Activity (OPA) at Day 30
Tidsramme: 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).
Day 30
Geometric Mean Fold Rise (GMFR) in Serotype-specific IgG From Day 1 (Baseline) to Day 30
Tidsramme: 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).
Day 1 (Baseline) and Day 30
GMFR in Serotype-specific OPA From Day 1 (Baseline) to Day 30
Tidsramme: 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).
Day 1 (Baseline) and Day 30
