Sanofi Pasteur will begin trials of its dengue vaccine in India. The trial will involve 120 adults and results should be made available by 2013. If all goes according to the set timeline, a vaccine will be available by 2015, the Times of India reports. "Sites for the vaccine's final trials will stretch from Thailand to India as this vaccine has to work on populations across countries," Sanofi ($SNY) CEO Chris Viehbacher told the news outlet. The company experienced a setback with the vaccine in September when study results showed the drug was only 30% effective against dengue fever type 2, far below the anticipated 70% efficacy rate.
