According to a press release by Sanofi, the results of the clinical trials have been very encouraging, especially because scientists have been struggling to develop a dengue vaccine for the past seven decades. The report further said that is the final trial also goes well, the vaccination can be available in the market by 2015.
The trials conducted so far have proved that the vaccine is safe for use. Although other drug companies are working on developing similar, Sanofi is the first company to come up with highly positive results. Dengue is a disease which is caused by an infected mosquito.
