Sanofi will work on developing a vaccine against Zika virus, the mosquito-borne pathogen whose explosive spread has touched off a global public health emergency.

The French drugmaker plans to harness its work against dengue fever to attack Zika, a virus from the same family, Sanofi said in a statement on Tuesday. The Paris-based company’s Sanofi Pasteur vaccines unit won approval in December in Brazil and Mexico for the world’s first inoculation against dengue.
