The development of a blood-stage malaria vaccine has largely focused on the subunit approach. However, the limited success of this strategy, mainly due to antigenic polymorphism and the failure to maintain potent parasite-specific immune responses, indicates that other approaches must be considered. Whole parasite (WP) vaccines offer many advantages over sub-units; they represent every antigen on the organism, thus limiting the effects of antigenic polymorphism, and similarly they compensate for individual Immune-Response (Ir) gene-regulated non-responsiveness to any particular antigen. From a development perspective, they negate the need to identify and compare the relative efficacies of individual candidate antigens. WP vaccines induce protective immunity that is largely cell-mediated.
