Campaign aims to leave no child unvaccinated in 19 countries

More than 85 million children under five years old will be immunized against polio in 19 countries across west and central Africa in a massive example of cross-border cooperation aimed at stopping a year-long polio epidemic.
Over 400 000 volunteers and health workers will take part in the campaign, which is part of an ongoing response to the epidemic that first spread from polio-endemic Nigeria to its polio-free neighbours in 2008 and is still paralysing children in west and central Africa. Nine countries – Burkina Faso, Cameroon, Chad, Guinea, Liberia, Mali, Mauritania, Senegal and Sierra Leone – are considered to have active outbreaks of polio (i.e. cases within the last six months). The campaign kicks off on March 6 in these countries as well as Nigeria, Ghana, Benin, Central African Republic, Gambia, Cape Verde and Guinea Bissau. Niger, Togo and Cote d’Ivoire will join at a later date due to political transitions or elections.

This complex logistical operation is largely made possible by US$ 30 million in extraordinary funding released by Rotary International, a major partner in the global effort to stop polio.

WHO Regional Director for Africa, Dr Luis Gomes Sambo, said the synchronized campaign showed Africa’s determination to be free of polio. “From the top leadership to local district administrators in every country,” he said, “we are each accountable to the African child – to vaccinate every child and achieve high coverage.”

A previous round of campaigns in 2009 did not stop the outbreak completely, as not enough children were vaccinated to stop polio transmission. After years with no polio cases, some countries lacked the necessary skills and experience to respond adequately to the outbreak. New approaches being introduced this year include standardized, independent monitoring of whether children have been reached, better training for vaccinators to carry out the plans fully and appropriate deployment of experienced staff.

UNICEF’s Regional Director for West and Central Africa, Dr Gianfranco Rotigliano noted: “With better coverage that leaves no child unvaccinated, these campaigns can succeed in making West and Central Africa polio-free.”

Getting real-time campaign coverage data

The Global Polio Eradication Initiative is implementing new approaches to improve the quality and impact of eradication strategies. One critical step is to obtain complete and rapid data on supplementary immunization activities (SIAs), so that mid-course corrections can be made if any gaps are found.

To this end, the GPEI is exploring the feasibility of consolidating internationally-available independent monitoring data within 10-14 days of an SIA. The WHO Regional Office for Africa has seized the opportunity of the recent campaigns in west Africa for this pilot. The report focuses on six countries of west Africa which are currently experiencing an outbreak following importation of wild poliovirus of Nigerian origin.

While some of the low numbers of missed children demonstrate that refinements are needed, the basic elements of a real-time independent monitoring report are present. These include the number and source of independent monitors, the number of children monitored, the percentage whose fingers were marked to prove they were vaccinated and the proportion of districts monitored.

Once reviewed, adjusted and endorsed by the Advisory Committee on Poliomyelitis Eradication in November, this process will be adapted for scale-up beyond the pilot phase. Real-time, independent monitoring data will reliably answer the question, “How many children did we reach with vaccine?” and allow course corrections rapidly to cover missing children and stop polio transmission more swiftly.
