Cuban scientists are undertaking studies on the effectiveness of a new  candidate vaccine against tuberculosis, a disease considered as  sanitary emergency in the world since 1993.

Doctor Iliana Valdes, from the Havana-based Pedro Kouri Tropical Medicine Institute, told reporters that her experts’ team adopted the strategy to use a micro-bacterium isolated in Cuban labs since 1971, which has proven its possible protection against tuberculosis, given the results obtained from tests in animals. “We are now in the pre-clinical stage using lab animals and we still have to go through other models before considering human beings,” said the specialist.
