Brazil to start clinical tests on new vaccine against dengue fever
SAO PAULO (AFP) - Brazilian scientists will next month begin clinical tests on humans of a new vaccine against dengue fever, a leading Sao Paulo-based biomedical research institute said on Thursday.
The vaccine is being developed to combat the four closely related strains of dengue viruses that have been identified around the world, the Butantan institute said in a statement.
Brazil is frequently afflicted with the disease, which is spread by the mosquito Aedes aegypti.
Work on the vaccine began in 2005 in partnership with the United States National Institutes of Health (NIH), Butantan said.
