15 August 2016 - One of Africa's biggest-ever emergency vaccination campaigns starts this week in Democratic Republic of the Congo with the aim to protect millions of people against yellow fever before the rainy season begins in late September.

Working with Ministries of Health in the 2 countries, WHO is coordinating 56 global partners to vaccinate more than 14 million people against yellow fever in more than 8000 locations. The yellow fever outbreak has found its way to dense, urban areas and hard-to-reach border regions, making planning for the vaccination campaign especially complex.
