The outbreaks of yellow fever in Angola, Democratic Republic of the Congo and Uganda have placed great demand on the global supply of yellow fever vaccines. The global stockpile of 6 million vaccines for emergency response (normally enough for a year) has already been replenished twice this year.
This timeline shows the demands on the global vaccine supply since early 2016.
The ongoing yellow fever outbreak in Angola is mostly in urban areas but at risk of spreading to other provinces and across borders to neighbouring countries. Extensive local transmission in the capital city Luanda, has prompted multiple vaccination campaigns in Angola as well as in Democratic Republic of the Congo and Uganda.
Read WHO’s latest guidance on communication and social mobilization methods to conduct yellow fever vaccination campaigns. The guidance also provides information on the monitoring and evaluation of communication and social mobilization techniques. These 10 points from field experience are especially useful for district-level planning. The document is available in English, French and Portuguese. A Spanish version is also in a pipeline.
Yellow fever: Facts and challenges
How is yellow fever transmitted? Is there a vaccine? Why is an urban yellow fever outbreak such a concern? Dr Sylvie Briand, Director of Pandemic and Epidemic Diseases Department at WHO gives answers to these and other questions in this short, informative video.
The Director-General of WHO, Dr Margaret Chan, went to Angola’s capital Luanda in the beginning of April 2016 for a two-day visit to assess the situation of the current outbreak of yellow fever virus.
“This is the most serious outbreak of yellow fever that Angola has faced in 30 years,” said Dr Chan, who visited a vaccination point in Luanda. “WHO is taking urgent action to support the Government to control this outbreak with a widespread vaccination campaign.”

The yellow fever outbreak, which was first reported in the capital city Luanda in December 2015, has since spread to 6 of the country’s 18 provinces.
WHO has taken urgent action to contain this outbreak, working with the Angolan Ministry of Health and partners to vaccinate people in the affected provinces, using vaccines from the International Coordination Group emergency stockpile.
