When the Global Polio Eradication Initiative launched in 1988, wild poliovirus paralyzed 350,000 children annually across 125 countries. Today, the disease survives in only two: Pakistan and Afghanistan. Pakistan's nationwide vaccination campaign from February 2-8, 2026, reached 44.3 million of 45 million targeted children under five across 159 districts—achieving over 98% coverage in the final push to eliminate a disease that would become only the second human pathogen ever eradicated, after smallpox.
The campaign concluded successfully one week ago, with provincial breakdowns: Punjab (22.9M), Sindh (10.5M), Khyber Pakhtunkhwa (7.13M), Balochistan (2.36M). Approximately 1 million children were missed due to refusals (53,000 recorded, concentrated in Karachi), amid Pakistan's cases dropping from 74 in 2024 to 30 in 2025 with no new cases since September 2025. Health officials note the low-transmission season offers the best chance to break transmission, despite ongoing challenges from vaccine hesitancy and past militant attacks.

Fictional AI pastiche — not real quote.
"The eradication of disease, like the conquest of territory, demands not merely good intentions but the willingness to enter dangerous ground where others fear to tread. Those 200 martyred health workers understood what princes often forget: that the greatest victories require men who will carry out necessary work in hostile lands, even when the populace mistakes their mercy for conspiracy. One might call it fortune that the virus now retreats—but I observe it is the persistence of the brave, not the prayers of the timid, that drives pestilence from its final strongholds."

Scenarios
1
Pakistan, Afghanistan Achieve Zero Wild Polio Cases by End of 2026
Discussed by: WHO Emergency Committee, GPEI leadership, and the Gates Foundation have identified the 2026 low-transmission season as a critical window
Pakistan's four-month streak without new cases and Afghanistan's relatively low numbers create the best opportunity in years. If synchronized campaigns maintain high coverage in border corridors and the Taliban permits expanded vaccination access, both countries could reach zero transmission. This would trigger a three-year countdown to formal eradication certification.
2
Transmission Persists in Cross-Border Corridors
Discussed by: WHO surveillance experts and epidemiologists tracking the YB3A genetic clusters
The 2,640-kilometer Afghanistan-Pakistan border has persistent transmission corridors that have resisted elimination for years. Continued Taliban restrictions on house-to-house vaccination, combined with population displacement and vaccine refusals, allow the virus to survive in hard-to-reach communities. Cases remain in double digits annually, and the 2027 eradication target is pushed back again.
3
Funding Shortfall Forces Campaign Reductions
Discussed by: GPEI leadership and donor countries concerned about the $440 million funding gap
Despite the Abu Dhabi pledges, traditional government donors have cut development assistance by 30%. If the funding gap isn't closed, campaign frequency or geographic reach may be reduced. Surveillance weakens, missed children accumulate, and gains reverse—as happened when cases spiked from 8 in 2018 to 74 in 2024.
4
Polio Becomes Second Human Disease Eradicated
Discussed by: Global health historians and WHO certification bodies
Following the elimination of wild poliovirus, intensive campaigns successfully contain vaccine-derived variants by 2029. The Global Commission certifies polio as the second human disease eradicated after smallpox—a 41-year effort that prevented an estimated 20 million cases of paralysis and saved $27 billion in treatment costs. The polio infrastructure transitions to broader immunization and disease surveillance.
Historical Context
Smallpox Eradication (1980)
1967-1980
What Happened
The World Health Organization launched an intensified eradication campaign in 1967, when smallpox killed 2 million people annually. Using a combination of mass vaccination and 'ring vaccination' (targeting contacts of infected individuals), the campaign reached the last natural case in Somalia in October 1977. The WHO declared smallpox eradicated in May 1980.
Outcome
Short Term
Vaccination programs ended worldwide, saving an estimated $1 billion annually in vaccine and administration costs.
Long Term
Remains the only human disease ever eradicated. The success provided the template and confidence for the polio campaign, demonstrating that global coordination could eliminate a pathogen entirely.
Why It's Relevant Today
Polio eradication would make it only the second human disease eliminated, using many of the same strategies—mass vaccination, surveillance, and ring containment—developed during the smallpox campaign.
India's Polio-Free Certification (2014)
1994-2014
What Happened
India once accounted for 60% of global polio cases. In 2009 alone, India reported 741 cases—nearly half the world total. Through campaigns that delivered 1 billion vaccine doses annually to 172 million children, combined with community mobilization to overcome vaccine hesitancy in Muslim communities, India achieved its last case in January 2011 and was certified polio-free in March 2014.
Outcome
Short Term
The WHO South-East Asia Region was certified wild polio-free, eliminating a major reservoir.
Long Term
India's success proved that even the most challenging environments—with dense populations, poor sanitation, and vaccine resistance—could achieve eradication. It demonstrated the biological and technical feasibility of global elimination.
Why It's Relevant Today
India's path offers a template for Pakistan: intensive door-to-door campaigns, community engagement to address vaccine hesitancy, and sustained political commitment over decades.
Africa's Wild Polio-Free Certification (2020)
1996-2020
What Happened
Nigeria was Africa's last endemic country, recording its final wild polio case in August 2016 in Borno State—an area where Boko Haram insurgency had blocked vaccination teams. Four years of sustained surveillance and vaccination, even in conflict zones, confirmed elimination. In August 2020, Africa became the fifth WHO region certified wild polio-free.
Outcome
Short Term
Five of six WHO regions achieved wild polio-free status, leaving only the Eastern Mediterranean Region (containing Pakistan and Afghanistan) with endemic transmission.
Long Term
Demonstrated that eradication is achievable even amid active insurgency, but requires sustained effort for years after the last case to prevent resurgence.
Why It's Relevant Today
Africa's experience in Borno State—eliminating polio despite militant activity—offers lessons for Pakistan's conflict-affected areas in Khyber Pakhtunkhwa and Balochistan.
