Safety and Immunogenicity of Locally Manufactured Oral Cholera Vaccine

Summary

To evaluate and compare the safety and immunogenicity of the Cholvax with ShancholTM, Investigators will conduct a clinical trial study Bangladeshi healthy adults and children. Cholvax is locally produced orally administered whole cell inactivated bivalent cholera vaccine. Incepta vaccine Limited, a leading pharmaceutical company in Bangladesh is now producing the oral cholera vaccine, Cholvax with technological support from International Vaccine Institute (IVI). Cholvax meets international Good Manufacturing Practice (GMP) standards and WHO production guidelines. Cholvax has the same formulation as ShancholTM in terms of strains and formulation. By this transfer of technology, it expected that the vaccine will become available for use in public health programs in Bangladesh and in the future in other cholera-affected countries in Asia and Africa to control endemic cholera, as well as to help control large-scale epidemics and outbreaks. Investigators will also evaluate and compare the safety and immunogenicity of 3 Cholvax lots (lot-to-lot consistency).
