This week, more than 138,000 vaccinators will fan out across five African countries in the Lake Chad area in a push to eliminate polio in Africa and rid the world of this terrible disease forever.
They will take boats across fast-flowing rivers, ride jeeps along sandy ravines, walk crowded streets in towns and cities and navigate cramped quarters of refugee camps to ensure that every child is immunised. Traveling for hours a day, these dedicated women and men will visit children in homes, schools, train stations, and transit points across Nigeria, Niger, Chad, Cameroon, and the Central African Republic.
This also marks World Immunisation Week, a coordinated effort to make sure that people everywhere understand the importance of getting immunised to protect against vaccine-preventable diseases.
And by coincidence, it was almost seven years ago that the two of us first met in a hotel conference room in Abuja, Nigeria’s capital. We were there as part of a diverse group—public officials, religious leaders, business people, polio survivors, and journalists—to discuss how we could work together to stop polio in Nigeria.
At the time, Nigeria had done an amazing job tackling polio—reducing reported cases by 95 percent in just one year. But it was still circulating in six Nigerian states. While 95 percent might seem like success, as long as a single child remains infected, children across Africa and around the world are at risk.
Thanks to the effort of so many, Nigeria’s Borno State is now the only place in Africa today where polio is still circulating. It will take ingenuity to end polio there, and it will take persistence to continue reaching children in the surrounding areas with vaccines to protect them from the disease until it is eradicated. But we’re confident it can be done. And when that happens, Africa will celebrate one of the biggest victories ever in public health.
Since our first meeting in 2010, the two of us have worked together on a range of other projects to help improve health in Nigeria and across Africa.
We supported the establishment of emergency operations centres in Nigeria and other countries to keep polio from spreading. This turned out to be a blessing during the 2014 Ebola outbreak in West Africa. When the disease first appeared in Nigeria—an international travel hub that is home to more than 180 million people—the staff of an emergency operations centre set up in Lagos jumped into action and stopped the disease in its tracks. It’s almost unimaginable to think what would have happened without them.
In the state of Kano, we are working with the government to ensure that children can get essential childhood immunisations against tetanus, pneumonia, liver cancer and measles. And when parents bring their children into a clinic for vaccinations, health workers can address other health issues, too, like nutrition, care for pregnant mothers and newborns and malaria prevention and treatment. We have since widened the programme to several other states.
Vaccines are also one of the best tools to save lives in an epidemic, such as the meningitis C outbreak happening now in Nigeria and other West African countries.
And because of the devastating impact malnutrition has on Nigeria’s children – leading to 300,000 deaths annually and causing stunted growth and development in millions more – we have expanded our partnership to include nutrition programmes across 12 states.
Earlier this year, we also helped launch the End Malaria Council, a group of influential public and private sector leaders committed to ensuring that malaria eradication remains a top global priority.
Underlying all these efforts is our belief that strengthening health systems is the key to breaking the cycle of extreme poverty and disease—and kick-starting a virtuous cycle of health, productivity, and prosperity.
In our work together, we have learnt a few important lessons.
First, improving the health of communities depends on a successful partnership between government, communities, religious and business leaders, volunteers, and NGOs. This ensures that everyone is rowing in the same direction. And it is essential to building trust so parents have the confidence that vaccines are safe and will protect their children from life-threatening diseases.
Second, we must keep innovating to speed up progress. This month, for example, vaccinators will test a new vaccine carrier that keeps the temperature of vaccines stable for up to five days, even in blistering heat. This breakthrough will enable vaccinators to finally reach children in extremely remote areas with life-saving vaccines.
Last, accurate and reliable data is central to any effort to improve health. Data can tell a health officer which communities are running low on vaccine supplies, where there are gaps in vaccination coverage, and which new mothers need reminders to take their babies to the health clinic to be immunised.
An Africa without polio is within reach. So is the vision of getting life-saving vaccines to every child. Success will generate more enthusiasm and support from across different sectors – government, business, civil society, the media – to tackle other killer diseases and the underlying conditions that affect people’s health, including fixing broken health systems.
We know that strengthening health systems takes time and diligence. We are optimistic that Africa can achieve the future it aspires to. That future depends on people working together—across national borders and across socioeconomic strata—to build the better world we all want.
