A study of different buffers to maximize viability of an oral Shigella vaccine.

Live, whole cell killed and subunit vaccines are being developed for diarrheal diseases caused by V. cholerae, Shigella species, ETEC, and Campylobacter. Some of these vaccines can be administered orally since this route best mimics natural infection.

Combination vaccines against diarrheal diseases.

Diarrheal diseases remain a leading cause of global childhood mortality and morbidity. Several recent epidemiological studies highlight the rate of diarrheal diseases in different parts of the world and draw attention to the impact on childhood growth and survival. Despite the well-documented global burden of diarrheal diseases, currently there are no combination diarrheal vaccines, only licensed vaccines for rotavirus and cholera, and Salmonella typhi-based vaccines for typhoid fever.

Characterization of a novel fusion protein from IpaB and IpaD of Shigella spp. and its potential as a pan-Shigella vaccine.

Shigellosis is an important disease in the developing world, where about 90 million people become infected with Shigella spp. each year. We previously demonstrated that the type three secretion apparatus (T3SA) proteins IpaB and IpaD are protective antigens in the mouse lethal pulmonary model.

Enteric vaccines for pediatric use. Workshop summary.

Diarrheal diseases remain a major cause of death in children under 5 in less developed countries (LDCs). Vaccine development and implementation offers the best near-term approach to alleviating this problem. For this reason, a workshop to examine the possibilities for making enteric vaccines available to meet the specific needs of children in LDCs was convened in Virginia on April 24-26, 2004.
