PeshawarPakistan has recorded 3 polio cases this year.
Khyber Pakhtunkhwa is deploying 35,000 security personnel alongside 22,450 vaccination teams across 23 districts where the polio and militant maps overlap, provincial authorities said.
North Waziristan and Bannu — each with an active environmental sample — begin their campaign Monday.

THE LAST RESERVOIRS
Wild poliovirus type 1 is endemic in only two countries on Earth: Pakistan and Afghanistan. Every other nation has eliminated transmission. The virus survives in a corridor along the Durand Line where vaccination teams cannot operate freely.
WHY VACCINATORS ARE TARGETS
In 2011 the CIA ran a fake hepatitis B vaccination drive in Abbottabad to collect DNA samples confirming Osama bin Laden's family was hiding there. The operation, exposed months later, weaponized the trust polio teams had spent decades building. The TTP issued formal bans on vaccination in tribal areas; over 100 polio workers and police escorts have been killed in Pakistan since.
WHY THE ORAL VACCINE
The oral polio vaccine costs about 15 cents per dose, requires no needle, and a community health worker can administer it in seconds at a doorstep. The injectable version is safer but costs 20 times more and needs trained staff. Eradication campaigns in poor, insecure terrain are only possible because of the oral vaccine's logistics.
ENVIRONMENTAL SURVEILLANCE
Most polio infections are silent — only about 1 in 200 cases produces paralysis. By the time a child shows symptoms, hundreds in the community are already infected. Sewage sampling for viral RNA is now the early-warning system; a positive environmental sample in Bannu or North Waziristan means transmission is active even before a paralysis case appears.
THE TRIBAL BELT VACUUM
The districts named in this campaign — North Waziristan, Bannu, and the merged FATA agencies — sit in the security vacuum where the Pakistani state's writ has historically been thinnest. The 2018 merger of FATA into Khyber Pakhtunkhwa brought courts and laws on paper. The TTP's resurgence since 2021 has rolled much of that back, which is why a vaccination drive now needs one soldier for roughly every two vaccinators.
