title: Oral bacterial vaccine vectors for the delivery of subunit and nucleic acid vaccines to the organized lymphoid tissue of the intestine.
abstract: Bacterial vaccine vectors have the potential to deliver a number of antigens from bacterial, protozoan and viral pathogens. To further develop the utility of bacterial vaccine vectors we are currently evaluating three model systems: 1. A Salmonella-ETEC Vaccine Vector; 2. A Salmonella-HIV Vaccine Vector, and 3. Novel Live Bacterial Nucleic Acid Vaccine Vectors. Through our studies, and those of others, significant progress has been made toward bacterial vaccine vector systems that effectively deliver subunit and nucleic acid vaccines to the organized lymphoid tissue of the intestine. The practical reality of these findings is discussed.
