How do you protect millions of people from a deadly disease in the space of a few weeks?
That has been the challenge after a yellow fever outbreak has killed more than 400 people in Angola and neighbouring Democratic Republic of Congo.

Eight-year-old Yungi was among the first to receive the vaccination at one of the hundreds of stations set up across the city.

A worldwide shortage of the vaccine, which takes up to 18 months to produce, has forced those behind the campaign to improvise…

…so nurses have been giving people one-fifth doses of the vaccine. This smaller dose still provides protection from yellow fever for a year, but not for life, as with a full dose. This emergency approach is backed by the World Health Organization.

With limited supplies of yellow fever vaccine, every vial is precious. They have to be handled with care and kept cold at all times, a challenge in a country where daytime temperatures regularly exceed 30C.

Residents of Kinshasa, like Barmany and her daughter Malux, have received the vaccine free as part of the government-funded programme.

In Binza Ozone, a suburb of Kinshasa with a population of around 350,000 people, vaccines are taken from a central storage point to more than 100 vaccination sites spread across the community.

They are transported in 4×4 vehicles to distribution centres. The city, which has a population of more than 10 million, lacks proper sanitation and is filled with puddles of standing water – the perfect breeding ground for the mosquitoes that spread yellow fever.

Hundreds of thousands of people have been heading to vaccination sites in Kinshasa, joining the early-morning queues. Charity Save the Children says it reached more than 200,000 people in one suburb of Kinshasa in the space of four days.
