Outcomes

Primary Outcome Measures

Number of Participants With Immediate Unsolicited Adverse Events (AEs) After Any Vaccination
An unsolicited AE was an observed AE that did not fulfill the conditions prelisted in the case report book (CRB) in terms of diagnosis and/or onset window post-vaccination. Unsolicited AEs includes both serious (SAEs) and non-serious unsolicited AEs. An SAE was any untoward medical occurrence that at any dose resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, or was an important medical event. All participants were observed for 30 minutes after vaccination, and any unsolicited systemic AEs occurred during that time were recorded as immediate unsolicited AEs in the CRB.
Number of Participants With Unsolicited Adverse Events After Any Vaccination
An unsolicited AE was an observed AE that does not fulfill the conditions prelisted in the CRB in terms of diagnosis and/or onset window post-vaccination. Unsolicited AEs included both serious and non-serious unsolicited AEs. An SAE was any untoward medical occurrence that at any dose resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, or was an important medical event. Adverse reactions (ARs) were AEs related to vaccination. An injection site reaction was an AR at and around the injection site. Systemic AEs were all AEs that were not injection or administration site reactions.
Number of Participants With Serious Adverse Events (SAEs) After Any Vaccination
An SAE was any untoward medical occurrence that at any dose resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, or was an important medical event. An SAE which caused death of the participant was considered as fatal SAE. Adverse events of special interest (AESIs) were defined as SAEs which included new onset of Guillain-Barré syndrome, encephalitis/myelitis (including transverse myelitis), Bell's palsy, convulsions, optic neuritis, and brachial neuritis.
Number of Participants Achieving Seroconversion Against Antigens Following Vaccination With Either a High-Dose Quadrivalent Influenza Vaccine or Standard-Dose Quadrivalent Influenza Vaccine or Adjuvanted Trivalent Influenza Vaccine
Anti-influenza antibodies were measured by hemagglutination inhibition (HAI) assay for strains A/H1N1, A/H3N2, B/Victoria and B/Yamagata lineage. Seroconversion: defined as either HAI titer <10(1/dilution) at Day 0 and post-vaccination titer greater than or equal to (>=)40(1/dilution) at Day 28, or HAI titer >=10(1/dilution) at Day 0 and >=4-fold increase in HAI titer (1/dilution) at Day 28. Data for this Outcome Measure (OM) was planned to be collected and reported for dose level (QIV-HD 30μg and 45μg) matched separate groups for QIV-SD (Groups 4a, 4b and 4c), instead of pooled QIV-SD arm. Due to complex study design and analysis of doses and age groups, QIV-SD group participants, who matched to participants in QIV-HD 30μg and 45μg dose formulations groups (who were 9 through 17 years old and shared matching age group with QIV-SD control group), included in Groups 4a, 4b and 4c in this OM might be counted in more than once in QIV-SD arms for different dose levels, as applicable.
Geometric Mean Titers (GMTs) of Influenza Antibodies Following Vaccination With Either a High-Dose Quadrivalent Influenza Vaccine or Standard-Dose Quadrivalent Influenza Vaccine or Adjuvanted Trivalent Influenza Vaccine
GMTs of anti-influenza antibodies were measured using an HAI assay for 4 strains: A/H1N1, A/H3N2, B Victoria lineage, and B Yamagata lineage. Data for this OM was planned to be collected and reported for dose level (QIV-HD 30 μg and QIV-HD 45 μg) matched separate groups for QIV-SD (Groups 4a, 4b and 4c), instead of pooled QIV-SD arm. Due to the complex study design and analysis of the dose formulation and age groups in the study, QIV-SD group participants, who matched to participants in the QIV-HD 30 μg and QIV-HD 45 μg dose formulations groups (who were 9 through 17 years old and shared a matching age group with QIV-SD control group), included in Groups 4a, 4b and 4c in this OM might be counted in more than once in QIV-SD arms for different dose levels, as applicable.
Geometric Mean Titer Ratios (GMTRs) of Influenza Antibodies Following Vaccination With Either a High-Dose Quadrivalent Influenza Vaccine or Standard-Dose Quadrivalent Influenza Vaccine or Adjuvanted Trivalent Influenza Vaccine
GMTs of anti-influenza antibodies were measured using an HAI assay for 4 strains: A/H1N1, A/H3N2, B Victoria lineage, and B Yamagata lineage. GMTRs were calculated as the ratio of GMTs post-vaccination and pre-vaccination.
Number of Participants With Neutralization Antibody Titers >= 40 (1/Dilution) Following Vaccination With Either a High-Dose Quadrivalent Influenza Vaccine or Standard-Dose Quadrivalent Influenza Vaccine or Adjuvanted Trivalent Influenza Vaccine
GMT was measured for each influenza strain using HAI assay method for 4 strains: A/H1N1, A/H3N2, B/Victoria lineage, and B/Yamagata lineage.
Geometric Mean Titers of Influenza Antibodies (Measured by Seroneutralization [SN] Assay) Following Vaccination With Either High-Dose Quadrivalent Influenza Vaccine or Standard-Dose Quadrivalent Influenza Vaccine or Adjuvanted Trivalent Influenza Vaccine
GMT was measured for each influenza strain using SN assay method for 4 strains: A/H1N1, A/H3N2, B/Victoria lineage, and B/Yamagata lineage.
Geometric Mean Titers Ratio of Influenza Antibodies (Measured by Seroneutralization Assay) Following Vaccination With Either High-Dose Quadrivalent Influenza Vaccine or Standard-Dose Quadrivalent Influenza Vaccine or Adjuvanted Trivalent Influenza Vaccine
GMTRs of anti-influenza antibodies were measured using SN assay method for 4 strains: A/H1N1, A/H3N2, B/Victoria lineage and B/Yamagata lineage. GMTRs were calculated as the ratio of GMTs post vaccination and pre-vaccination.
Number of Participants With Neutralization Antibody Titers Above Pre-Defined Thresholds
Neutralizing Antibody titer was measured for each influenza strain with SN assay method for 4 strains: A/H1N1, A/H3N2, B/Victoria lineage, and B/Yamagata lineage at pre-defined thresholds of >=20, >=40 and >=80 (1/dilution).
Number of Participants With Two-Fold and Four-Fold Increase in Neutralization Antibody Titer
Neutralizing Antibody titer was measured for each influenza strain with SN method for 4 strains: A/H1N1, A/H3N2, B/Victoria lineage, and B/Yamagata lineage. 2-fold and 4-fold rise was defined as the computed value = post-vaccination computed value / pre-vaccination computed value.
Number of Participants With Solicited Injection Site Reactions
A solicited reaction was an expected adverse reaction (sign or symptom) observed and reported under the conditions (nature and onset) prelisted (i.e., solicited) in the CRB and considered as related to the administered vaccination. Solicited injection site reactions included tenderness/pain, erythema, swelling, induration and bruising.
Number of Participants With Solicited Systemic Reactions After Any Vaccination

To describe the antibody response induced by each dosage of QIV-HD used in the study compared with unadjuvanted QIV-SD by virus seroneutralization (SN) measurement method. To describe the antibody response induced by the highest acceptable dosage of QIV-HD compared with adjuvanted trivalent influenza vaccine (TIV) by HAI and virus SN measurement methods.
Detailed Description
Study duration per participant was approximately 180 days for participants who received one dose of vaccine and 208 days for participants who received two doses of vaccine.

For previously influenza vaccinated participants: Previous vaccination against influenza in the preceding 6 months with either the study vaccine or another vaccine. For previously influenza unvaccinated participants: Any influenza vaccination (from birth to the day of inclusion) with either the study vaccine or another influenza vaccine. For previously influenza unvaccinated participants: Any previous laboratory confirmed influenza infection (from birth to the day of inclusion) Receipt of immune globulins, blood or blood-derived products in the past 3 months. Known or suspected congenital or acquired immunodeficiency; or receipt of immunosuppressive therapy, such as anti-cancer chemotherapy or radiation therapy, within the preceding 6 months; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks within the past 3 months).
