A Phase 3, Multicenter, Randomized, Double-blind, Active Comparator-controlled Study to Evaluate the Safety, Tolerability, and Immunogenicity of Catch-up Vaccination Regimens of V114 in Healthy Infants, Children, and Adolescents (PNEU-PLAN)

Geometric Mean Concentration of Serotype-specific Immunoglobulin G - Schedule A: 7-11 Months

时间窗: 30 days post last vaccination

The geometric mean concentration (GMC) of immunoglobulin G (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 two serotypes (22F and 33F) which are unique to V114 was determined. Sera from participants was used to measure vaccine-induced anti-pneumococcal polysaccharides (PnPs) serotype-specific IgG for all the 15 serotypes using pneumococcal electrochemiluminescence (PnECL) assay. The within-group 95% confidence intervals (CIs) were derived by exponentiating the CIs of the mean of the natural log values based on the t-distribution.

GMC of Serotype-specific IgG - Schedule B: 12-23 Months

时间窗: 30 days post last vaccination

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 two serotypes (22F and 33F) which are unique to V114 was determined. Sera from participants was used to measure vaccine-induced anti-PnPs serotype-specific IgG for all the 15 serotypes using pneumococcal electrochemiluminescence (PnECL) assay. The within-group 95% CIs were derived by exponentiating the CIs of the mean of the natural log values based on the t-distribution.

GMC of Serotype-specific IgG - Schedule C: 2-17 Years

时间窗: 30 days post vaccination

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 two serotypes (22F and 33F) which are unique to V114 was determined.

Percentage of Participants With Solicited Injection-site Adverse Events - Schedule A: 7-11 Months

时间窗: Up to 14 days post any vaccination

An adverse event (AE) is defined as any unfavourable and unintended sign, symptom, or disease temporally associated with the use of study vaccine or a protocol-specified procedure, whether or not considered related to the study vaccine or protocol-specified procedure. The parent/guardian of the participant recorded the presence of any vaccination report card (VRC)-prompted injection-site AEs that occurred in the 14 days after any vaccination. The percentage of participants with an injection-site AE prompted on the VRC (redness/erythema, hardness/induration, swelling, and pain) was summarized.

The percentage of participants with an injection-site AE prompted on the VRC (redness/erythema, hardness/induration, swelling, and pain) was summarized.

Percentage of Participants With Solicited Systemic AEs - Schedule C: 2-17 Years

时间窗: Up to 14 days post vaccination

An AE is defined as any unfavourable and unintended sign, symptom, or disease temporally associated with the use of study vaccine or a protocol-specified procedure, whether or not considered related to the study vaccine or protocol-specified procedure. The parent/guardian of the participant recorded the presence of any VRC-prompted systemic AEs that occurred in the 14 days after any vaccination. For participants 7 months to \<3 years of age at enrollment, solicited systemic AEs include irritability, drowsiness/somnolence, appetite lost/decreased appetite, and hives or welts/urticaria. For participants ≥3 years of age at enrollment, solicited systemic AEs include muscle pain/ myalgia, joint pain/arthralgia, headache, tiredness/fatigue, and hives or welts/urticaria. The percentage of participants with a systemic AE was summarized.

Percentage of Participants With at Least 1 Vaccine-related SAE - Schedule B: 12-23 Months

时间窗: Up to ~6 months post final vaccination

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. SAEs that are reported to be at least possibly related by the investigator to study vaccination will be summarized. Estimated within-group CIs are calculated based on the exact binomial method proposed by Clopper and Pearson and are provided in accordance with the statistical analysis plan.
