Abstract

Malaria during pregnancy is a major cause of intra-uterine growth-retardation and infant death in sub-Saharan Africa. Ideally, this could be prevented by a vaccine delivered before the first pregnancy. Antibodies against domain DBL4e{open} from VAR2CSA has been shown to inhibit adhesion of laboratory isolates to the placental receptor chondroitin sulfate A. In this study, the binding inhibitory efficacy of IgG elicited by two different DBL4e{open} recombinant proteins was tested on a panel of fresh clinical isolates from pregnant women living in Benin and Tanzania. The most promising recombinant protein elicited antibodies with similar efficacy as pooled plasma from immune multi-gravid African women.
