More than 190,000 polio vaccinators in 13 countries across west and central Africa will immunise more than 116 million children over the next week, to tackle the last remaining stronghold of polio on the continent.

The synchronised vaccination campaign, one of the largest of its kind ever implemented in Africa, is part of urgent measures to permanently stop polio on the continent. All children under five years of age in the 13 countries – Benin, Cameroon, Central African Republic, Chad, Côte d’Ivoire, Democratic Republic of Congo, Guinea, Liberia, Mali, Mauritania, Niger, Nigeria and Sierra Leone – will be simultaneously immunised in a coordinated effort to raise childhood immunity to polio across the continent. In August 2016, four children were paralysed by the disease in security-compromised areas in Borno state, north-eastern Nigeria, widely considered to be the only place on the continent where the virus maintains its grip.

“Twenty years ago, Nelson Mandela launched the pan-African ‘Kick Polio Out of Africa’ campaign,” Dr Matshidiso Moeti, WHO Regional Director for Africa, said yesterday in a statement. “At that time, every single country on the continent was endemic to polio, and every year, more than 75 000 children were paralysed for life by this terrible disease. Thanks to the dedication of governments, communities, parents and health workers, this disease is now beaten back to this final reservoir.”

Dr Moeti cautioned, however, that progress was fragile, given the epidemic-prone nature of the virus. Although confined to a comparatively small region of the continent, experts warned that the virus could easily spread to under-protected areas of neighbouring countries. That is why regional public health ministers from five Lake Chad Basin countries – Cameroon, Central African Republic, Chad, Niger and Nigeria – declared the outbreak a regional public health emergency and have committed to multiple synchronised immunisation campaigns.

UNICEF Regional Director for West and Central Africa, Ms Marie-Pierre Poirier, stated that with the strong commitment of Africa’s leaders, there was confidence that this last remaining polio reservoir could be wiped out, hereby protecting all future generations of African children from the crippling effects of this disease once and for all. “Polio eradication will be an unparalleled victory, which will not only save all future generations of children from the grip of a disease that is entirely preventable – but will show the world what Africa can do when it unites behind a common goal.”

To stop the potentially dangerous spread of the disease as soon as possible, volunteers will deliver bivalent oral polio vaccine (bOPV) to every house across all cities, towns and villages of the 13 countries. To succeed, this army of volunteers and health workers will work up to 12 hours per day, travelling on foot or bicycle, in often stifling humidity and temperatures in excess of 40°C.

Each vaccination team will carry the vaccine in special carrier bags, filled with ice packs to ensure the vaccine remains below the required 8°C.

“This extraordinary coordinated response is precisely what is needed to stop this polio outbreak,” said Michael K McGovern, Chair of Rotary’s International PolioPlus Committee. “Every aspect of civil society in these African countries is coming together, every community, every parent and every community leader, to achieve one common goal: to protect their children from life-long paralysis caused by this deadly disease.”

The full engagement of political and community leaders at every level – right down to the district – is considered critical to the success of the campaign. It is only through the full participation of this leadership that all sectors of civil society are mobilised to ensure every child is reached.
