text1: Currently, there is no specific treatment available against dengue fever, which is the most widespread tropical disease after malaria. Sanofi Pasteur is collaborating with the Communicable Disease Center in Singapore and the Pasteur Institute in Vietnam to conduct these clinical studies in children and adults. "Controlling the mosquitoes that transmit dengue is necessary but not sufficient to fight against the disease. A safe and effective vaccine has been long awaited to prevent dengue epidemics," said Professor Leo Yee Sin, director of the Communicable Disease Center in Singapore. "Clinical studies in Singapore are critical steps to advance the development of a vaccine for the prevention of dengue in Asia. We are happy to contribute to scientific research that would benefit the entire region."
