Fears of global yellow fever epidemic grow as vaccine stocks dwindle
One of the largest emergency vaccination campaigns ever attempted aims to stop virus taking hold in central #Africa
A last-ditch effort to prevent #yellow fever spreading through Kinshasa in the #Democratic Republic of the Congo and potentially developing into a global epidemic is to be launched using vaccines containing a fifth of the normal dose because the global stockpile is so low.
Yellow fever is frequently lethal, killing half of those who develop severe symptoms. It is transmitted by the bite of the Aedes aegypti mosquito, which is also responsible for the spread of Zika virus. There is a vaccine which protects people for life, but few adults had been immunised in #Angola when yellow fever broke out there in December last year, and in the DRC, to where it has spread.
