Antibody responses to individual and optimal combinations of P. vivax recombinant proteins in naturally-exposed populations help to identify correlates of protective immunity, and establish a clear path to testing a multicomponent P. vivax vaccine.
Optimised genome editing in P. knowlesi enables transgenic expression of a lead P. vivax vaccine candidate, revealing roles in host cell tropisms and providing tools for scalable vaccine efficacy testing.
Under sustained malaria control in PNG, the incidence of distinct blood-stage infections quantifies heterogeneity in transmission, significantly predicting risk of both P. falciparum and P. vivax malaria episodes at a population and individual scale.
Plasmodium parasite transcription shifts dramatically along asexual development, and transmission stages variably express important immune evasion genes, suggesting much interesting biology has until now been hidden by bulk analyses.
The structure of the promising malaria blood-stage vaccine candidate antigen PfCyRPA and the characterization of a protective epitope are facilitating research on its essential role in parasite invasion, and will guide future epitope-focused vaccine design.
