Study Endpoints
Primary Endpoints
Safety evaluation of OVX836 (180µg and 480µg)
From enrollment to the end of trial at 180 days.

Description: Proportion of subjects reporting: - solicited local and systemic symptoms within 7 days after vaccine administration - unsolicited AEs within 29 days after vaccine administration - SAEs during the entire study duration - ILIs and RT-PCR confirmed influenza A or B (overall and occurring more than 14 days post-vaccination, i.e., vaccine failure), RSV and/or SARS-CoV-2.

Secondary Endpoints
Cell-mediated immune response to OVX836 (180μg and 480μg) in term of NPspecific IFNγ spot forming cells frequencies in peripheral blood (ELISPOT)
at Days 1, 8 and 29
Frequencies of NP-specific CD4+ and CD8+T-cells expressing IL-2, TNFα and/or IFNγ, measured by flow cytometry, following in vitro stimulation of PBMC
at Days 1, 8 and 29
Cross-reactivity of the NP influenza-specific responses by IFNγ ELISPOT against selected circulating and emerging strains of influenza
at Days 1, 8 and 29
