Clinical Trial Summary

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.
