Altruistic vaccines: take them after you get sick and your blood becomes mosquito-poison

A dengue fever vaccine being developed with funding from the Gates Foundation takes a novel approach: it's an "altruistic" vaccine that you take after you get sick. It renders your blood poisonous to the mosquitoes who spread the disease, which means that your neighbors won't catch your fever.

Professor Young says dengue is a problem which affects millions around the world and mosquito transmitted pathogens such as dengue and malaria are a significant disease burden on the world's population.

His aim is to develop a novel vaccine approach that is based on blocking mosquito transmission of these disease agents rather than inducing pathogen-specific immunity.
