Malaria vaccine based on self-assembling protein nanoparticles

Abstract

Despite recent progress with GSK’s RTS,S malaria vaccine, there remains a desperate need for an efficient malaria vaccine. We have used a repetitive antigen display technology to display malaria specific B cell and T cell epitopes in an effort to design a vaccine against Plasmodium falciparum malaria. Our protein sequence when assembled into a nanoparticle induces strong, long-lived and protective immune responses against infection with the parasite. We are confident that the clinical trials with our most developed vaccine candidate will show good protection in a controlled human malaria infection trial.
