[Development of oral cholera vaccine and its vaccination].

The application of the cholera vaccine is one of the cholera prevention and control strategies. Cholera vaccines stimulate mucosal immune to play the role of antibacteria and antitoxin. When the cholera toxin B subunit is added in the cholera vaccine, it could also defend against some diarrhea associated pathogens by cross-protection. Oral inactivated cholera vaccines are commercially available now. The oral live vaccine candidates are under development. The development of cholera vaccine is not only on the technical aspect, based on the situations of epidemic areas and population, cost, storage and transportation condition should also be considered. Though the argument on the use of cholera vaccine in epidemic areas and population in high risk existed previously, its vaccination has reached agreement now based on the clinical trials and evaluations during epidemic period.
