30 May Havana Cuba :Scientists
here have developed a new cholera vaccine and are ready to do "field testing" in Africa before it is marketed worldwide, officials
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, said its vice president Francisco Dominguez.
"The research showed the antigen is
safe and highly effective," Dominguez said.
The next step will be to test whether
immunisation with the new vaccine maintains its efficacy in countries that have high incidences of cholera, and where people
have secondary conditions from malnutrition to malaria or AIDS, Dominguez told reporters.
Cuba has held talks with Mozambique,
Equatorial Guinea and South Africa on possible testing there.
Cholera, which had been all but wiped out in Latin America,
staged a deadly comeback in the 1990s, claiming thousands of lives.
The Instituto Finlay has been behind
a number of new vaccine developments.
It developed the only effective vaccine against type B meningitis which Cuba markets
in several countries around the world.
