More than 400,000 volunteers and health workers will use special carriers to ensure the vaccine remains below the required temperature of 8 C, WHO said in a fact sheet.
Workers will travel by foot, bicycle, cars, boats and motorcycles to deliver the vaccines during the campaign, which is mainly funded by Rotary International.
An outbreak of polio that started in Nigeria in the second half of 2008 has been spreading in western Africa northward to Mauritania.
Last year in Nigeria, the only country in Africa where the polio virus is still transmitted or endemic, the number of cases collapsed.
The door-to-door vaccination strategy has helped stop the outbreak in Benin, Côte d’Ivoire, the Central African Republic, Ghana, Togo and Niger, WHO said.
Polio is a highly infectious disease caused by a virus. It invades the nervous system and can lead to irreversible paralysis, usually of the legs, in one in 200 infections, according to the Global Polio Eradication Initiative.
