About this study

This randomized, double-blind, placebo-controlled, Phase 1 trial will enroll up to 22 malaria-naïve, adult participants to test safety, tolerability, immunogenicity, and efficacy of the genetically attenuated Plasmodium falciparum sporozoite vaccine (PfSPZ-LARC2) Vaccine. PfSPZ-LARC2 Vaccine is a late-arresting, replication-competent whole Plasmodium falciparum sporozoite product. We hypothesize that the PfSPZ-LARC2 Vaccine will be safe from breakthrough infection by virtue of deletion of two key parasite genes Mei2 and LINUP and may be more immunogenic and protective than previously tested early arresting sporozoite vaccines. The primary objective is to assess the tolerability and safety of administration of PfSPZ-LARC2 Vaccine, with special attention to the adequacy of attenuation.
