ISLAMABAD: Pakistan has vaccinated more than 43.8 million children in five days of its last nationwide polio campaign of 2025, health authorities said on Saturday, as the drive entered its sixth day amid renewed efforts to curb the virus.

The campaign, running from Dec. 15 to 21, targets children under the age of five and is being conducted simultaneously in Pakistan and Afghanistan, according to Pakistan’s National Emergency Operations Center (NEOC) which oversees eradication efforts.

Pakistan and neighboring Afghanistan are the only two countries where wild poliovirus transmission has never been interrupted, keeping global eradication efforts at risk. The virus, which can cause irreversible paralysis, has no cure and can only be prevented through repeated oral vaccination.

“The last nationwide polio campaign of 2025 continues in full swing on the sixth day,” the NEOC said in a statement. “Over 43.8 million children have been vaccinated in five days so far.”

Provincial data released by the National EOC showed that around 22.7 million children had been vaccinated in Punjab province, more than 10.2 million in Sindh, approximately 6.9 million in Khyber Pakhtunkhwa and about 2.5 million in Balochistan. In Islamabad, over 450,000 children received polio drops, while more than 274,000 were vaccinated in Gilgit-Baltistan and over 714,000 in Azad Jammu and Kashmir.
