The Reach of Yellow Fever

Yellow fever is transmitted by mosquitos, with endemic viral circulation in 47 countries across Africa and Central and South America. Unvaccinated travelers can catch the infection while visiting these areas and even bring the disease back to their home countries.2

Protecting People Worldwide

Sanofi is part of the EYE Strategy which supports routine vaccination programs and Preventive Mass Vaccination Campaigns.  We’re proud to be a major supplier to GAVI’s Global international stockpile to fight epidemics, where we commit to deliver doses within 72h.

We’re also investing in a new generation vaccine which would aim to support strong global supply.
