Assessment of vaccine efficacy using a combination of Rv21 with viral-vectored vaccines expressing P. vivax TRAP (vvTRAP) or an unrelated transgene (vvControl). (A) Table indicating the vaccination components in an 8-week prime-boost regimen, utilized to compare the efficacy against a sporozoite challenge with a combination of a P. vivax VLP (Rv21), a P. falciparum VLP (R21) with vvTRAP, or an unrelated nonmalaria antigen vvControl. (B) Survival of mice (n = 6) after a sporozoite challenge with the vaccination regimens described in panel A. (C) Titer of anti-PvCSP antibodies by Rv21 or a combination of Rv21 plus vvTRAP. (D) Ex vivo IFN-γ responses against TRAP measured by ELISpot assay. SFU, spot-forming units.
