Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objectives of the study are:

* To describe the safety profile of the different quadrivalent recombinant influenza vaccine (RIV) formulations.
* To describe the hemagglutination inhibition (HAI) and seroneutralization (SN) antibody responses against hemagglutinin (HA) (H1, H3, B/Victoria, and B/Yamagata) antigens present in the control vaccine in all groups at all timepoints.

The secondary objectives of the study are:

* To describe antigenic coverage in each group by assessing the HAI and SN antibody responses against a panel of H3 antigens (not present in any of the vaccine formulations).
* To describe HAI and SN antibody responses in each group against each of the H3 antigens.
* To compare the HAI and SN antibody responses for the groups with different H3 antigens to the control group.

Exclusion Criteria

* Participant is 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 12 weeks after vaccination. 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 4 weeks preceding the 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 4 weeks preceding the study vaccination or planned receipt of any vaccine in the 4 weeks following study vaccination

* Previous vaccination against influenza in the 2019-2020 season with any licensed influenza 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)
* Have known active or recently active (12 months) neoplastic disease or a history of any hematologic malignancy
* History of influenza infection during the 2018-2019 or 2019-2020 influenza season, confirmed by laboratory tests (including rapid tests)
* Self-reported or documented seropositivity for human immunodeficiency virus, hepatitis B, or hepatitis C
* 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 intramuscular vaccination based on Investigator's judgement
* Deprived of freedom by an administrative or court order, or in an emergency setting, or hospitalized involuntarily
* Alcohol abuse or substance abuse that, in the opinion of the investigator, might interfere with the study conduct or completion
* Chronic illness that, in the opinion of the investigator, is at a stage where it might interfere with study conduct or completion or predispose to complications associated with influenza infection
