Brief summary

The aim of the study was to assess the immunogenicity and safety of Fluzone Quadrivalent influenza vaccine Southern Hemisphere (SH) 2015 formulation in participants aged 18 to 60 years as well as in participants 61 years or older. The objectives were: * To evaluate the compliance, in terms of immunogenicity, of the Fluzone Quadrivalent influenza vaccine SH 2015 formulation with the requirements of the European Medicines Agency (EMA) Note for guidance (NfG) CPMP/BWP/214/96 * To describe the immunogenicity of the Fluzone Quadrivalent influenza vaccine SH 2015 formulation * To describe the safety of the Fluzone Quadrivalent influenza vaccine SH 2015 formulation

Detailed description

All participants received 1 intramuscular dose of Fluzone Quadrivalent vaccine at the first visit. Immunogenicity and safety were assessed in all participants. Adverse events (AE) defined in EMA NfG CPMP/BWP/214/96 were collected for 3 days after vaccination, solicited AE pre-listed in the diary card were collected for 7 days after vaccination, unsolicited AEs were collected for 21 days after vaccination, and serious adverse event (SAE) information was collected throughout the study.

Exclusion criteria

* History of serious adverse reaction to any influenza vaccine. * Receipt of any vaccine within 30 days before receiving study vaccine, or plans to receive another vaccine before Visit 2. * Participation in another interventional clinical trial investigating a vaccine, drug, medical device, or medical procedure in the 30 days preceding the first study vaccination or during the course of the study. * Self-reported thrombocytopenia, which may be a contraindication for intramuscular vaccination, at the discretion of the Investigator. * Vaccination against influenza in the previous 12 months if administered in the context of a clinical trial or a flu vaccination campaign. * Known systemic hypersensitivity to eggs, chicken proteins, or any of the vaccine components, or a history of a life-threatening reaction to the vaccine or to a vaccine containing any of the same substances (the complete list of vaccine components is included in the Prescribing Information) . * Receipt of immune globulins, blood, or blood-derived products in the past 3 months. * Bleeding disorder or receipt of anticoagulants in the 3 weeks preceding inclusion, which may be a contraindication for intramuscular vaccination, at the discretion of the Investigator. * Participant was pregnant, or lactating, or of childbearing potential (to be considered of non-childbearing potential, a female must be post-menopausal for at least 1 year, surgically sterile, or using an effective method of contraception or abstinence from at least 4 weeks prior to vaccination and until at least 3 weeks after vaccination). * 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 Guillain-Barré syndrome. * 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). * Chronic illness that, in the opinion of the Investigator, is at a stage where it might interfere with trial conduct or completion . * Known seropositivity for human immunodeficiency virus (HIV), hepatitis B, or hepatitis C, as reported by the participant.
