Abstract: | Recent advances in scientific research and clinical trials have shown promise for vaccine development against enteric pathogens. Identification of new virulence factors, such as the two distinct shigella enterotoxins, has allowed the development of new immunogen or new attenuated strains. Improved knowledge facilitated the development of safer attenuated live microorganism and construction of multivalent vaccines. Finally, an important advantage is the use of nonreplicating plasmid DNA vectors to express protective antigens in the host. |
