Malaria pre-erythrocytic antigens as a fusion polypeptide and their use in the elicitation of a protective immune response in a host

摘要

The invention relates to chimeric Plasmodium antigenic polypeptides derived from pre-erythrocytic (PE) antigens and associated in a fusion polypeptide. In particular, the invention relates to antigenic fusion polypeptides of malaria parasites wherein said antigenic polypeptides exhibit a protective effect, especially that of eliciting a protective immune response in a host against challenge by Plasmodium sporozoites or a sterile response. Such identified antigenic fusion polypeptides may thus constitute active ingredients suitable for the design of a vaccine candidate, in particular a vaccine suitable for a human host.
