Nigeria starts largest yellow fever mass vaccination Nigeria will begin a Yellow Fever vaccination campaign to inoculate 25 million people. The Nigerian government, along with the WHO and UNICEF, plan to carry out the mass campaign in 2018, making it the country's largest ever vaccination drive. It is part of a wider global effort to eradicate Yellow Fever outbreaks by 2026 and will begin in Nigeria in Kogi, Kwara and Zamfara states. Nigeria is currently battling an outbreak of yellow fever, which began in the west in September 2017. In late 2017, it vaccinated more than three million people, but this did not stop the spread of the disease. About 45 people have so far died from Yellow Fever this year.
