DENV-specific CD4+ T-cell responses in adults and/or adolescents in the US, Thailand and Puerto Rico. DENV-specific CD4+ T-cell responses after immunization with the F17 or F19 vaccines are presented for the overall sample subset of adults in the US and Thailand, and adolescents and adults in Puerto Rico (a), and for US subjects stratified by their DENV priming status at baseline, with numbers of evaluated subjects as indicated (b). Blood samples were obtained prior to each dose (Day [D] 0 and month [M] 6), 1 and 3 months after both the first dose (M1 and M3) and the second dose (M7 and M9). Data are presented in box-and-whiskers plots as percentages of DENV-specific CD4+ T cells expressing (after in vitro stimulation) at least two immune markers among IFN-γ, IL-2, TNF-α and CD40L of all CD4+ T cells, with medians, first and third quartiles, and minimum/maximum values presented.
