Model systems to evaluate the use of transgenic haematophagous insects to deliver protective vaccines

Insect vector control has proved an effective method for reducing the transmission of disease-causing organisms to human populations in many tropical countries. We are interested in employing direct genetic manipulation of insect vector genomes to use them in beneficial ways so as to have a profound and long-lasting effect on disease transmission. Our research focuses on assessing whether haematophagous insects may be used as a means to deliver protective proteins, such as an antimalarial vaccine, when they take a blood meal. The progress which has been made towards assessing this concept using a number of model systems is described.
