Clinical Trial Summary

The aim of the study was to describe the safety and immunogenicity of the 2016-2017 formulations of Fluzone Quadrivalent vaccine in children 3 to < 9 years of age and in adults 18 to < 65 years or age, and of the 2016-2017 formulation of Fluzone High-Dose vaccine in adults ≥65 years of age.

Primary Observational Objectives

• To describe the safety of the 2016-2017 formulation of Fluzone Quadrivalent vaccine in children 3 to < 9 years of age and adults 18 to < 65 years of age, and the safety of the 2016-2017 formulation of Fluzone High-Dose vaccine in adults ≥ 65 years of age.

Observational Objectives:

• To describe the immunogenicity of the 2016-2017 formulation of Fluzone Quadrivalent vaccine in children 3 to < 9 years of age and adults 18 to < 65 years of age, and the immunogenicity of the 2016-2017 formulation of Fluzone High-Dose vaccine in adults ≥ 65 years of age.

• To submit available sera from approximately 90 participants (30 participants 3 to < 9 years of age and 30 participants 18 to < 65 years of age who receive Fluzone Quadrivalent vaccine, and 30 participants ≥ 65 years of age who receive Fluzone High-Dose vaccine) to Center for Biologics Evaluation and Research (CBER) for further analysis by the World Health Organization (WHO), the Centers for Disease Control and Prevention (CDC), and the Food and Drug Administration (FDA) to support formulation recommendations for subsequent influenza vaccines.

Description:

All participants received a 0.5-mL intramuscular dose of their assigned vaccine at Visit 1. For participants 3 to < 9 years of age for whom 2 doses of influenza vaccine were recommended per Advisory Committee on Immunization Practices (ACIP) guidance, a second dose of Fluzone Quadrivalent vaccine (of the same volume) was administered during Visit 2.

Solicited adverse reaction (AR) information was collected for 7 days after vaccination. Unsolicited non-serious adverse event (AE) and serious adverse event (SAE) information was collected from Visit 1 to Visit 2 or from Visit 1 to Visit 3 for those participants receiving 2 doses of study vaccine.

Immunogenicity was evaluated in all participants prior to vaccination on Day 0 (Visit 1) and after the final vaccination on Day 28 for 3 to < 9 year olds and Day 21 days for adults 18 years and older.

To be considered of non-childbearing potential, a female must be pre-menarche, or post-menopausal for at least 1 year, or surgically sterile.

• Participation at the time of study enrollment (or in the 30 days preceding the first trial vaccination) or planned participation during the present trial period in another clinical trial investigating a vaccine, drug, medical device, or medical procedure.

• Receipt of any vaccine in the 30 days preceding the first trial vaccination, or planned receipt of any vaccine before Visit 2 for participants receiving 1 dose of influenza vaccine or Visit 3 for participants receiving 2 doses of influenza vaccine.

• Previous vaccination against influenza (in the 2016-2017 influenza season) with either the trial vaccine or another vaccine.

• 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 vaccine used in the trial or to a vaccine containing any of the same substances.

• Thrombocytopenia, which may be a contraindication for intramuscular vaccination, at the discretion of the Investigator.

• Bleeding disorder, or receipt of anticoagulants in the 3 weeks preceding inclusion, contraindicating intramuscular vaccination.

• 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, is at a stage where it might interfere with trial conduct or completion.

• Moderate or severe acute illness/infection (according to Investigator judgment) on the day of planned vaccination or febrile illness (temperature =100.4°F [38.0°C]). A prospective participant should not be included in the study until the condition has resolved or the febrile event has subsided.

• Identified as an Investigator or employee of the Investigator or study center with direct involvement in the proposed study (participants =18 years of age) or identified as an immediate family member (i.e., parent, spouse, natural or adopted child) of the Investigator or employee with direct involvement in the proposed study (all participants).

• History of serious adverse reaction to any influenza vaccine.

• 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 developmental delay (at the discretion of the Investigator), neurologic disorder, or seizure disorder.

• Known seropositivity for human immunodeficiency virus, hepatitis B, or hepatitis C.
