BACKGROUND
After continuous exposure to malarial infections in regions of Africa where malaria is hyperendemic, children attain clinical immunity. This immunity results, in part, from the acquisition of antibodies against a large repertoire of variant antigens expressed on the surface of infected
The Plasmodium merozoite surface antigen 2 (MSA2) is one of several candidates for a protective vaccine against malaria. Previous studies have shown that antibodies directed against the MSA2 variable region are not protective and that constant regions are non-immunogenic. However, modified peptides
Multiple antigen peptide constructs (MAPs) have been used to obtain defined multimeric peptide molecules useful in the development of possible synthetic malaria vaccines. In this context, a method was developed, named double dimer constructs (DDCs), involving the direct synthesis of a dimeric
Invasion of human erythrocytes by Plasmodium vivax requires interaction between Duffy binding protein (PvDBP) and the Duffy blood group antigen. The receptor-binding domain of PvDBP lies in a conserved N-terminal, cysteine-rich region, region II (PvRII). PvRII is a valuable malaria subunit vaccine
