Malaria Vaccine Development

Developing vaccines against malaria-causing parasites, including the dormant form of Plasmodium vivax

Technology Overview

Dr. Noah SatherDr. Noah Sather

Approximately 1/3 of the world’s population is at risk for contracting malaria.  Malaria is caused by infection with Plasmodium parasites, including P. falciparum, the deadliest form, and P. vivax, the most geographically widespread form. Both forms of malaria exact a massive human and economic toll.  The Sather lab is focused on the development of a vaccine to prevent both forms of malaria.  In the case of P. vivax, vaccine development is complicated by the existence of a dormant liver form that can activate years after initial infection, causing a relapse of symptomatic, blood-stage, transmissible disease. In fact, most cases of active, blood-stage P. vivax malaria are caused by reactivation of dormant parasites. Therefore, targeting this stage of the disease could reduce illness and dramatically curb or eliminate transmission.

A major focus of Dr. Sather’s research is vaccine and therapy development, including the prevention of primary infection with P. falciparum and clinical relapse infection with P. vivax. The Sather lab is actively developing novel vaccine candidates and evaluating their ability to prevent infection.  To bolster these efforts, they and their collaborators developed a recombinant antibody that distinguishes between the dormant and replicating forms of P. vivax.This tool will help advance research on P. vivax liver-stage disease.

In addition to his expertise in analyzing host-pathogen interactions at the molecular level and developing technologies and tools for researching these interactions, Dr. Sather has experience designing novel immunogens and analyzing their immunogenicity. His collaborators include clinical partners in countries where malaria is endemic.

Dr. Sather is interested in exploring partnerships that advance preclinical vaccine development for Plasmodium falciparum and Plasmodium vivax malaria. Examples of partner projects include: 1) developing malaria vaccine formulations with clinical-grade adjuvants; 2) exploring nanoparticles as carriers for malaria vaccines, and 3) working on malaria vaccine development with partners with good manufacturing practice (GMP) facilities.
