ISLAMABAD: Pakistan has vaccinated approximately 36.4 million children as the third nationwide polio vaccination campaign of the year entered its fourth day today, Thursday, the country’s polio program said.

Around 400,000 frontline workers, including 225,000 women vaccinators, are driving the campaign launched on Monday to vaccinate 45 million children under the age of five. The drive will conclude on June 1. 

Polio is a paralyzing disease with no cure. Multiple doses of the oral polio vaccine, along with the completion of the routine immunization schedule for all children, are essential to ensure strong immunity against the disease.

Pakistan and Afghanistan are the last two countries in the world where polio remains endemic. Pakistan has reported 10 polio cases so far this year, compared to 74 cases in 2024.

“In the first three days, 81 percent of (45 million) children across the country have been vaccinated,” the National Emergency Operations Center (NEOC) said in a statement.

“85 percent in Punjab, 68 percent in Sindh, 86 percent in Khyber Pakhtunkhwa and 74 percent of children in Balochistan have been vaccinated.”

The report said 63 percent of children were administered polio drops in the federal capital, Islamabad, 93 percent in Azad Jammu and Kashmir and 91 percent in Gilgit-Baltistan.

In the early 1990s, Pakistan reported around 20,000 polio cases annually but in 2018 the number dropped to eight cases. Six cases were reported in 2023 and only one in 2021. 

Pakistan’s polio program began in 1994, but efforts to eradicate the virus have been repeatedly undermined by vaccine misinformation and resistance from some religious hard-liners who claim that immunization is a foreign plot to sterilize Muslim children or a cover for Western espionage.

Militant groups have also frequently targeted polio vaccination teams and the security personnel assigned to protect them, often resulting in deadly attacks.

A Pakistani police officer was killed earlier this week when gunmen opened fire on a team of health workers carrying out a polio vaccination drive in the volatile Balochistan province on the second day of a door-to-door campaign.
