The primary objectives of the study are: - To describe the safety profile of the different formulations in all participants - To describe the hemagglutinin inhibition (HAI) and seroneutralization (SN) antibody responses against hemagglutinin (H1, H3, B/Victoria, and B/Yamagata) antigens present in the control vaccine in all groups at all timepoints. The secondary objectives 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 SN antibody responses in each group against each of the H3 antigens. - To compare H3 HAI and SN antibody responses for the groups with quadrivalent recombinant influenza vaccine (RIV) formulations with H3 antigens to those of the quadrivalent RIV control group. - To compare the HAI and SN antibody responses for the groups with quadrivalent RIV formulation with adjuvant to the group without adjuvant.

Participants with isolated primary (essential) hypertension are allowed - Moderate or severe acute illness/infection (according to investigator judgment) on the day of vaccination or febrile illness (oral 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, or identified as an immediate family member (ie, parent, spouse, natural or adopted child) of the investigator or employee with direct involvement in the proposed study - Personal or family history of Guillain-Barré syndrome - History of chronic kidney disease - Current or past diagnosis of thyroid disease (eg, thyroiditis [including Hashimoto's thyroiditis], hyperthyroidism, and hypothyroidism) The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial. |
