Identification of serological markers of protection and risk for dengue vaccines and natural infection

Project Summary Dengue remains stubbornly endemic in many countries. Vaccine development efforts have been hampered by a poor understanding of the immune response. We do know that pre-existing immunity from vaccination or historic infections is key to driving disease risk, however, accurate markers of risk or protection are lacking, including how they change over multiple years. Less is known about the role of non-neutralizing antibody functions, such as antibody-dependent cell cytotoxicity, and antibody-dependent enhancement in driving disease risk. Neutralizing and non-neutralizing antibody responses have not been characterized alongside cellular immune responses that have been identified…
