PARIS (REUTERS) - The world's first vaccine against dengue, developed by French drugmaker Sanofi, has shown the ability to protect against disease caused by three of four dengue virus strains in a keenly awaited clinical trial in Thailand.
Sanofi said on Wednesday the proof of efficacy was 'a key milestone' in the 70-year quest to develop a viable dengue shot, adding the results also confirmed the safety profile of the vaccine candidate.
