Africa has been certified free of wild poliovirus — one of the most significant public health achievements in the continent’s history. The Africa Regional Certification Commission made the announcement after confirming that more than 95% of Africa’s population had been immunized, a threshold the commission required before granting certification. A disease that paralyzed more than 75,000 children across the continent in a single year has been stopped in its tracks.
At a glance
- Wild poliovirus: Africa has been cleared of all wild strains of the virus, leaving only Afghanistan and Pakistan as remaining reservoirs of wild polio worldwide.
- Vaccination campaign: More than 95% of Africa’s population is now immunized, following decades of village-to-village outreach that delivered billions of oral polio vaccines.
- Cases averted: Since 1996, the Africa-wide effort is estimated to have prevented 1.8 million cases of wild poliovirus paralysis across the continent.
Twenty-five years of work
The road to this milestone began in earnest in 1996 C.E., when Nelson Mandela launched the “Kick Polio Out of Africa” programme. Millions of health workers fanned out across the continent, going village to village to hand-deliver vaccines. The effort was backed by a broad coalition that included Rotary International, which had been driving polio vaccination since the 1980s.
Two key tools made eradication possible. The injectable polio vaccine, developed in 1952 C.E. by Dr. Jonas Salk, showed the world that children could be protected. Then in 1961 C.E., Albert Sabin pioneered the oral polio vaccine — cheaper, easier to deliver, and now used in national immunization programs across the globe.
Two of the three strains of wild poliovirus have already been eradicated worldwide. This certification covers the final remaining strain on the African continent.
Nigeria’s hard-won victory
Nigeria was the last African country to be declared free from wild polio — and arguably faced the steepest climb. Less than a decade ago, Nigeria accounted for more than half of all global polio cases. The last confirmed case of wild polio on the continent was recorded in 2016 C.E. in Borno state, in Nigeria’s remote northeast and the epicenter of the Boko Haram insurgency.
Reaching children in that region required extraordinary commitment. Frontline workers — 95% of them women — navigated conflict zones and remote waterways, crossing Lake Chad by boat to deliver vaccines. Some were killed in the process, including nine female vaccinators in two shootings in Kano in 2013 C.E.
Misinformation added another layer of difficulty. In 2003 C.E., several northern Nigerian states suspended immunizations after religious leaders spread false claims that the vaccine contained an anti-fertility agent. Nigerian scientists dismissed the accusations after laboratory testing, and campaigns resumed the following year — but rebuilding trust took time.
That trust was ultimately rebuilt, in part, by polio survivors themselves. Misbahu Lawan Didi, president of the Nigerian Polio Survivors Association, described the approach simply: survivors traveled to resistant communities, sometimes crawling long distances, to make the case in person. “We ask them: ‘Don’t you think it is important for you to protect your child not to be like us?'”
What the certification means — and what remains
The certification is a formal, independent verification by the World Health Organization’s Africa region, not just a self-reported milestone. It reflects sustained surveillance, high coverage rates, and years without any detected wild poliovirus transmission.
Still, the job is not finished. A separate challenge — vaccine-derived poliovirus — remains active in parts of Africa. This rare form occurs when the live virus in the oral vaccine mutates and spreads in under-immunized communities. In 2020 C.E., 177 cases had been identified, with the WHO tracking outbreaks in Nigeria, the Democratic Republic of the Congo, the Central African Republic, and Angola. Newer oral vaccines designed to reduce this risk are now being deployed.
There is also the ever-present threat of reimportation. Angola defeated wild polio in 2001 C.E. despite decades of civil war, then saw cases return in 2005 C.E., likely brought in from outside the country. The WHO has been clear: vaccination and surveillance must continue until global eradication is achieved. Wild polio can travel across borders quickly in under-immunized populations, making complacency the main remaining enemy.
What this certification does mark, unambiguously, is the end of an era. A disease that shaped — and cut short — millions of lives across Africa has been driven from the wild. The coalition that did it crossed every boundary of language, religion, politics, and geography to reach children one by one.
That, on its own, is worth remembering.
