Brazilian scientists are going to begin clinical tests on humans for a new low-cost and effective dengue fever vaccine next month.
A leading Sao Paulo-based biomedical research institute, Butantan, said that the vaccine is being developed to combat the four closely related strains of dengue viruses that have been identified around the world, News24 reports.
