Indeed, in the long search for a vaccine against malaria, successful clinical trials have been performed using chimeric nanoparticle antigens containing epitopes from the circumsporozoite protein (CSP) of the Plasmodium falciparum (P. falciparum) malaria parasite genetically fused either to HBcAg [59] (in Malarivax) or to HBsAg (in Mosquirix) [60]. The gene discussed is DNAJC5; the disease is malaria.
