As many as 3.44 million children under the age of five would be vaccinated against polio during the anti-polio campaign launched in 13 districts of the province, including Peshawar, Swat, Hangu and Kohat.
Pakistan and neighboring Afghanistan are the only two countries in the world where polio remains endemic.
Pakistan's polio cases are declining, with just 54 cases of wild polio virus reported last year, down more than 80 per cent from 2014.
A total of 10029 teams have been constituted comprising 19,256 vaccinators and 2,101 Area Incharges to reach out to the target population, he added.
He said that teams have been given special training to cope with the programmatic challenges and to successfully achieve the target.
Moreover, he said that special security measures have been taken to ensure security cover to the teams and smooth running of the campaign.
The attacks on polio health workers intensified after a Pakistani doctor was arrested on charges of running a fake vaccination campaign in Abbottabad as a cover for a CIA-backed effort to obtain DNA samples from Osama bin Laden ahead of the 2011 US raid that killed him.
The most recent deadly attack came in January when at least 15 people, mostly security officials, were killed and over 20 others injured when a Taliban suicide bomber blew himself up outside a polio vaccination centre in restive Balochistan's capital Quetta.
