About
The primary objective of the study was to provide sera (collected from participants before vaccination [Blood Sample 1] and after final vaccination [Blood Sample 2]) to the 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.
Full description
All participants received 1 intramuscular injection of the study vaccine associated with their assigned group at Visit 1. For participants 6 months to < 9 years of age for whom 2 doses of influenza vaccine are recommended per Advisory Committee on Immunization Practices (ACIP) guidance, a second intramuscular injection of Fluzone Quadrivalent vaccine was administered at Visit 2 (28 days after Visit 1).
Blood specimens were obtained from all participants prior to the first vaccination:
- At Visit 1 (Day 0) and 28 days following the final vaccination (Visit 2, if no study vaccine was administered at Visit 2; or Visit 3, if a second dose of study vaccine was administered at Visit 2), for participants 6 months to < 9 years of age (Group 1 and Group 2)
- At Visit 1 and 21 (window, 21-28) days post-vaccination (Visit 2), for participants greater than or equal to (>=) 65 years of age (Group 3) Serious Adverse Events (SAEs), suspected unexpected serious adverse reactions (SUSARs), or Adverse Event of Special Interests (AESIs) were collected from Visit 1 through Visit 2 for participants receiving 1 dose of study vaccine, and from Visit 1 through Visit 3 for participants receiving 2 doses of study vaccine.
Study duration per participant was approximately 28 days for participants 6 months to less than (<) 9 years of age, and 21 days for participants >= 65 years of age.

Exclusion criteria:
An individual who fulfilled any of the following criteria were excluded from study enrollment:
- Participation at the time of study enrollment (or in the 30 days 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 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 2019-2020 influenza season) with either study vaccine or another vaccine.
- Receipt of immune globulins, blood, or blood-derived products in the 3 months preceding planned inclusion.
- Known or suspected congenital or acquired immunodeficiency; or receipt of immunosuppressive therapy, such as anti-cancer chemotherapy or radiation therapy, within the 6 months preceding planned inclusion; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks within the 3 months preceding planned inclusion).
- Known systemic hypersensitivity to any of the vaccine components, or history of a life-threatening reaction to study vaccine or to a vaccine containing any of the same substances.

- Personal history of Guillain-Barré syndrome.
