Cuban scientists have developed a new cholera vaccine and are ready to do "field testing" in Africa before it is marketed worldwide, officials said.
The vaccine is derived from a live strain of a genetically modified bacillus that transmits cholera. It was successfully tested on 100 healthy subjects at Cuba's prestigious Instituto Finlay. Officials at the institute say research shows the antigen is safe and highly effective.
The next step will be to test whether immunization with the new vaccine maintains its efficacy in countries with high incidences of cholera, and where people have secondary conditions like malnutrition, malaria or AIDS.
