For the past decade, Sughra Ayaz has traveled door to door in southeastern Pakistan, pleading with parents to permit children to be vaccinated against polio as a part of a worldwide campaign to wipe out the paralytic disease. She hears their demands and fears. Some are practical – families need basics like food and water greater than vaccines. Others are simply unfounded – the oral doses are supposed to sterilize their kids.
Amid rampant misinformation and immense pressure for the campaign to succeed, Ayaz said, some managers have instructed staff to falsely mark children as immunized. And the vaccines, which have to be kept cold, aren’t all the time stored accurately, she added.
“In lots of places, our work isn’t done with honesty,” Ayaz said.
The World Health Organization and partners launched into their polio campaign in 1988 with the daring goal of eradication — a feat seen just once for human diseases, with smallpox in 1980. They got here close several times, including in 2021, when just five cases of the natural virus were reported in Pakistan and Afghanistan. But since then, cases rebounded, hitting 99 last yr, and officials have missed at the least six self-imposed eradication deadlines.
Afghanistan and Pakistan remain the one countries where transmission of polio — which is extremely infectious, affects mainly children under five, and may cause irreversible paralysis inside hours — has never been interrupted. The worldwide campaign has focused most of its attention and funding there for the past decade.
But in its quest to eliminate the disease, the Global Polio Eradication Initiative has been derailed by mismanagement and what insiders describe as blind allegiance to an outdated strategy and a problematic oral vaccine, in line with staff, polio experts and internal materials obtained by The Associated Press.
Officials have falsified vaccination records, chosen unqualified people to dole out drops, didn’t send out teams during mass campaigns, and dismissed concerns concerning the oral vaccine sparking outbreaks, in line with documents shared with AP by staffers from GPEI – certainly one of the biggest and costliest public health campaigns in history, with over $20 billion spent and nearly every country on the planet involved.
In Afghanistan and Pakistan – which share a border, harbor widespread mistrust of vaccines, and have weakened healthcare systems and infrastructure – local staffers like Ayaz have for years flagged problems to senior managers. But those issues, together with concerns by staffers and outdoors health officials, have long gone unaddressed, insiders say.
Officials tout the successes – three billion children vaccinated, an estimated 20 million individuals who would have been paralyzed spared – while acknowledging challenges in Pakistan and Afghanistan. Distant villages are hard to achieve, some cultural and spiritual authorities instruct against vaccination, and tons of of polio staff and security staff have been killed due to their alignment with a Western-led initiative.
Dr. Jamal Ahmed, WHO’s polio director, defended progress in those two countries, citing staff’ tailored response in resistant pockets.
“There’s so many children being protected today due to work that was done over the past 40 years,” he said. “Let’s not overdramatize the challenges, because that results in children getting paralyzed.”
Ahmed said he believes authorities will end the spread of polio in the subsequent 12 to 18 months. Its latest goal for eradication is 2029. The campaign says about 45 million children in Pakistan and 11 million in Afghanistan have to be vaccinated this yr. Children typically need 4 doses of two drops each to be considered fully immunized.
Dr. Zulfiqar Bhutta, who has served on advisory groups for WHO, the Gates Foundation and others, said campaign officials should take heed to the criticism of its tactics.
“Continuing blindly with the identical strategies that we’ve got relied on since eradication began is unlikely to steer to a unique result,” he said.
Documents show yearslong problems on polio vaccination teams
Internal WHO reports reviewing vaccination drives in Afghanistan and Pakistan over the past decade – given to AP by current and former staffers – show that as early as 2017, local staff were alerting significant problems to senior managers.
The documents flagged multiple cases of falsified vaccination records, medical experts being replaced by untrained relatives and staff improperly administering vaccines.

On quite a few occasions, WHO officials noted, “vaccinators didn’t find out about vaccine management,” citing failure to maintain doses properly cold. Additionally they found sloppy or falsified reporting, with staff noting “more used vaccine vials than were actually supplied.”
In accordance with an August 2017 report from Kandahar, Afghanistan, local government authorities and others interfered in selecting vaccinators, “leading to the choice of underage and illiterate volunteers.”
Vaccination teams worked “in a hurried manner,” reports said, with “no plan for monitoring or supervision.” A team in Nawzad, Afghanistan, covered just half of the intended area in 2017, with 250 households missed entirely. Village elders said nobody visited for at the least two years.
Vaccine staff and health officials in Afghanistan and Pakistan confirmed the problems within the documents and told AP it’s hard for campaign leadership to understand the difficulties in the sector. Door-to-door efforts are stymied by cultural barriers, unfounded stories about vaccines, and the region’s poverty and transience.
“More often than not once we go to vaccinate and knock on the door, the top of the home or the person isn’t at home,” said one employee, speaking on condition of anonymity because they weren’t authorized to refer to the press. “Many individuals find it offensive that a stranger knocks on the door and talks to a lady.”
Some staff find families have moved. Occasionally, they are saying, the encounter abuse.
“We have now shared these problems with our senior officials,” the employee told AP. “They find out about it.”
In an email response to AP’s questions on officials’ knowledge of the problems, WHO polio director Ahmed noted “operational challenges” in Afghanistan and Pakistan and said this system has “robust monitoring and evaluation processes.”
Employee Ayaz described “fake finger marking” — placing the ink used to indicate a toddler is vaccinated on their pinky even when no vaccine has been given.
“There’s a lot pressure,” Ayaz said.
Critics point to continued use of the oral polio vaccine
Before the primary polio vaccine was developed in 1955, the disease — spread mostly from individual to individual, through contaminated water and via fecal particles — was among the many world’s most feared, paralyzing tons of of hundreds of kids annually. People avoided crowded places during epidemics, and hospital wards full of children encased in iron lungs after the virus immobilized their respiration muscles.
Polio is principally spread when individuals are exposed to water infected with the virus. In countries with poor sanitation, children often grow to be infected once they come into contact with contaminated waste.
WHO says that so long as a single child stays infected, kids in all places are in danger.
Eradication demands near-perfection – zero polio cases and immunizing greater than 95 per cent of kids.
But public health leaders and former WHO staffers say campaign efforts are removed from perfect, and plenty of query the oral vaccine.
The oral vaccine – proven to be protected and effective — has been given to greater than three billion children. But there are some extremely rare negative effects: Scientists estimate that for each 2.7 million first doses given, one child might be paralyzed by the live polio virus within the vaccine.
In even rarer instances, the live virus can mutate right into a form able to starting latest outbreaks amongst unimmunized people where vaccination rates are low.
Worldwide, several hundred vaccine-derived cases have been reported annually since at the least 2021, with at the least 98 this yr.
Most public health experts agree the oral vaccine must be pulled as soon as possible. But they acknowledge there simply isn’t enough injectable vaccine — which uses no live virus and doesn’t include the risks of the oral vaccine — to wipe out polio alone. The injectable vaccine is also dearer and requires more training to manage.
Greater than two dozen current and former senior polio officials told AP the agencies involved haven’t been willing to even consider revising their technique to account for a number of the campaign’s problems.
Dr. Tom Frieden, a former director of the U.S. Centers for Disease Control and Prevention who sits on an independent board reviewing polio eradication, said it will be not possible to eliminate polio without the oral vaccine. But he’s urged authorities to seek out ways to adapt, resembling adopting latest methods to discover polio cases more quickly. Since 2011, he and colleagues have issued regular reports about overall program failures.
“There’s no management,” he said, citing an absence of accountability.
Last yr, former WHO scientist Dr. T. Jacob John twice emailed WHO Director-General Tedros Adhanom Ghebreyesus calling for a “major course correction.” John shared the emails with AP and said he’s received no response.
“WHO is persisting with polio control and creating polio with one hand and attempting to manage it by the opposite,” John wrote.
In his response to AP, WHO polio director Ahmed said the oral vaccine is a “core pillar” of eradication strategy and that “almost every country that’s polio-free today used (it) to realize that milestone.”
“We’d like to step back and really take care of the people,” he said. “The one way we are able to try this in large parts of the world is with oral polio vaccine.”
Ahmed also pointed to the success WHO and partners had eliminating polio from India, once considered an almost not possible task. Within the 4 years before polio was wiped on the market, medical experts delivered about 1 billion doses of the oral vaccine to greater than 170 million children.
Today, nearly the entire world’s polio cases — mostly in Africa and the Middle East — are mutated viruses from the oral vaccine, apart from Afghanistan and Pakistan.
Scott Barrett, a Columbia University professor, called for an inquiry into how things went so flawed – particularly with a failed effort in 2016, when authorities removed a strain from the oral vaccine. They miscalculated, resulting in outbreaks in greater than 40 countries that paralyzed greater than 3,000 children, in line with an authority report commissioned by WHO. Last yr, a mutated virus traced to that effort paralyzed a baby in Gaza.
“Unless you have got a public inquiry where all of the evidence comes out and WHO makes serious changes, it is going to be very hard to trust them,” he said.
Mistrust of the polio eradication effort persists
With an annual budget of about $1 billion, the polio initiative is amongst the most costly in all of public health. This yr, the U.S. withdrew from WHO, and President Donald Trump has cut foreign aid. WHO officials have privately admitted that sustaining funding can be difficult without success.
Some say the cash can be higher spent on other health needs.
“We have now spent greater than $1 billion (in external polio funding) within the last five years in Pakistan alone, and it didn’t buy us any progress,” said Roland Sutter, who formerly led polio research at WHO. “If this was a non-public company, we’d demand results.”
Villagers, too, have protested the associated fee, staging tons of of boycotts of immunization campaigns since 2023. As an alternative of polio vaccines, they ask for medicine, food and electricity.
In Karachi, locals told AP they didn’t understand the federal government’s fixation on polio and complained of other issues — dirty water, heroin addiction. Employees are accompanied by armed guards; Pakistani authorities say greater than 200 staff and police assigned to guard them have been killed because the Nineteen Nineties, mostly by militants.
The campaign is also up against a wave of misinformation, including that the vaccine is comprised of pig urine or will make children reach puberty early. Some blame an anti-vaccine sentiment growing within the U.S. and other countries which have largely funded eradication efforts and say it’s reaching even distant areas of Afghanistan and Pakistan.
In suburban southwest Pakistan, Saleem Khan, 58, said two grandchildren under five were vaccinated over his family’s objections.
“It ends in disability,” said Khan, without citing evidence for his belief. “They’re vaccinated because officials reported our refusal to authorities and the police.”
Svea Closser, professor of international health at Johns Hopkins University, said Pakistan and Afghanistan were less proof against immunization a long time ago. Now, individuals are indignant concerning the give attention to polio and lack of help for diseases like measles or tuberculosis, she said, spurring conspiracy theories.
“Polio eradication has created a monster,” Closser said. It doesn’t help, she added, that on this region, public trust in vaccine campaigns was undermined when the CIA organized a fake hepatitis drive in 2011 in an try and get DNA and ensure the presence of Osama bin Laden or his family.
Employees see that continued mistrust each day.
In a mountainous region of southeastern Afghanistan where most individuals survive by growing wheat and raising cows and chickens, a mother of 5 said she’d prefer that her children be vaccinated against polio, but her husband and other male relatives have instructed their families to reject it. They consider the false rumors that it is going to compromise their children’s fertility.
“If I allow it,” the lady said, declining to be named over fears of family retribution, “I might be beaten and thrown out.”
