Malaria Transmission Blocking Vaccines, Lukasz Jacek Sewera

Master's Theses

Malaria affects 198 million people and kills 584,000 each year, predominantly in Sub-Saharan Africa (WHO). The most severe form of malaria is caused by the protozoan parasite Plasmodium falciparum. Development of a vaccine against P. falciparum has been hindered by its complex life cycle with multiple antigenically distinct human and mosquito stages. To effectively prevent disease and reduce the parasite burden in populations, a vaccine will need to target multiple stages, including blocking transmission at the mosquito stage.

Antibodies generated against P. falciparum mosquito stage antigen Pfs25 can prevent parasite transmission from humans to mosquitoes. However, Pfs25 is poorly immunogenic …
