World's first dengue vaccine beats three virus strains

The world's first vaccine against dengue fever has protected against three of the virus's four strains in a keenly awaited clinical trial in Thailand.

French drugmaker Sanofi says the proof of efficacy is a key milestone in the 70-year quest to develop a viable dengue shot.
The company says the results also confirm the safety profile of its vaccine candidate.
The mosquito-borne disease is a threat to nearly 3 billion people and is caused by four different types of virus.
Sanofi's vaccine generated an antibody response for all four dengue virus types, but evidence of protection was only demonstrated against three of the four strains circulating in Thailand.
