An official with Cuba's biotechnology program says his country may develop a bird flu vaccine.
Carlos Borroto, with Cuba's Center for Genetic Engineering and Biotechnology, made the comment Thursday. But he said officials do not want to raise expectations because they are still studying the project's feasibility.
The official also said the two drugs now in use against avian flu are effective, but were not being produced in sufficient quantities.
The remarks come as Cuba prepares to host an international biotechnology conference in Havana. An estimated 500 scientists from 35 countries are expected at the talks, beginning November 27 in Havana.
Cuba's biotechnology industry is one of the most advanced in the developing world.
