Vaccination against Dengue

In 2015, Sanofi Pasteur introduced the first dengue vaccine which is registered in several of the most endemic countries in the world. Implementation of public dengue vaccination programs should be consistent with current approved labelling for the first available dengue vaccine in each country where it is approved, as well as by updated WHO position for the vaccine as part of integrated dengue prevention efforts that include vector control, disease management and surveillance.
