Eligibility Criteria:
Inclusion criteria :~* Aged 6 months to 17 years on the day of inclusion.~* Assent form was signed and dated by the participant (7 to 17 years of age) and informed consent form was signed and dated by the parent(s) or guardian(s) and by an independent witness, if required by local regulations.~* Participant and parent/guardian were able to attend all scheduled visits and complied with all study procedures.~* For participants aged \<24 months: Born at full term of pregnancy (greater than or equal to \[\>=\] 37 weeks) and/or with a birth weight \>=2.5 kilogram.~Exclusion criteria:~* Participant was pregnant, or lactating, or of childbearing potential and not using an effective method of contraception or abstinence from at least 4 weeks prior to vaccination until at least 4 weeks after vaccination. To be considered of non-childbearing potential, a female must be pre-menarche.~* Participation at the time of study enrollment (or in the 4 weeks preceding the first study vaccination) or planned participation during the present study period in another clinical study investigating a vaccine, drug, medical device, or medical procedure.~* Receipt of any vaccine in the 30 days preceding the first study vaccination, or planned receipt of any vaccine before Visit 3 for participants receiving 1 dose of influenza vaccine or Visit 5 for participants receiving 2 doses of influenza 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).~* Known systemic hypersensitivity to any of the vaccine components, or history of a life-threatening reaction to the vaccines used in the study or to a vaccine containing any of the same substances.~* Thrombocytopenia or bleeding disorder, contraindicating IM vaccination based on Investigator's judgement.~* Deprived of freedom by an administrative or court order, or in an emergency setting, or hospitalized involuntarily.~* Current alcohol abuse or drug addiction.~* Chronic illness that, in the opinion of the investigator, was at a stage where it might interfere with study conduct or completion.~* Moderate or severe acute illness/infection (according to investigator judgment) on the day of vaccination or febrile illness (temperature \>=38.0°Celsius \[\>=100.4°Fahrenheit\]). A prospective participant should not be included in the study until the condition had resolved or the febrile event had subsided.~* Identified as an immediate family member (i.e., spouse, natural or adopted child, grandchild, nephew, or niece) of the Investigator or employee with direct involvement in the proposed study.~* Personal history of Guillain-Barré syndrome.~* Any condition that in the opinion of the Investigator would pose a health risk to the participant if enrolled or could interfere with the evaluation of the vaccine~* Personal history of clinically significant development delay (at the discretion of the Investigator), neurologic disorder, or seizure disorder.~* Known seropositivity for hepatitis B or hepatitis C.~The above information was not intended to contain all considerations relevant to a participant's potential participation in a clinical trial.

Study Arms:
- Group 1: QIV-HD 30 μg (US: 6 months to 17 years) (Type: EXPERIMENTAL): Participants from United States (US) (aged 6 months to 17 years) received single injection of 30 microgram (μg) QIV-HD, intramuscularly (IM) at Day 0. Participants for whom 2 doses of influenza vaccine were recommended, a second dose was administered at Day 28.
- Group 2: QIV-HD 45 μg (US: 6 months to 17 years) (Type: EXPERIMENTAL): Participants from US (aged 6 months to 17 years) received single injection of 45 μg QIV-HD, IM at Day 0. Participants for whom 2 doses of influenza vaccine were recommended, a second dose was administered at Day 28.
- Group 3: QIV-HD, 60 μg (US: 6 months to 17 years) (Type: EXPERIMENTAL): Participants from US (aged 6 months to 17 years) received single injection of 60 μg QIV-HD, IM at Day 0. Participants for whom 2 doses of influenza vaccine were recommended, a second dose was administered at Day 28.
- Group 4: Pooled QIV-SD, 15 μg (US: 6 months to 17 years) (Type: ACTIVE_COMPARATOR): Pooled arm consisted of participants who were from US aged 6 months to 17 years, randomized to Groups 1, 2 and 3 and received single injection of 15 μg QIV-SD, IM at Day 0. Participants for whom 2 doses of influenza vaccine were recommended, a second dose was administered at Day 28.
- Group 5: QIV-HD, 60 μg (Canada: 6 to <24 months) (Type: EXPERIMENTAL): Participants from Canada (aged 6 to less than \[\<\] 24 months) received single injection of 60 μg QIV-HD, IM at Day 0. Participants for whom 2 doses of influenza vaccine were recommended, a second dose was administered at Day 28.
- Group 6: Adjuvanted TIV (Canada: 6 to <24 months) (Type: ACTIVE_COMPARATOR): Participants from Canada (aged 6 to \<24 months) received single injection of 7.5 μg adjuvanted TIV, IM at Day 0. Participants for whom 2 doses of influenza vaccine were recommended, a second dose was administered at Day 28.
