The charismatic former Pakistan captain was born in Khyber district, which is part of the militant-infested tribal belt, and campaigners hope his Pashto credentials can persuade parents to inoculate their children.

“It is a noble cause and I am happy to be part of smashing polio from Pakistan which has crippled many children,” Afridi told AFP.

He said the main target was remote areas of Pakistan, such as the Al-Qaeda and Taleban infested tribal belt on the Afghan border.

“I am from that area and speak their language, so I will try to go door-to-door to remove any negative concept about the campaign and I hope this will help us raise healthy future generations,” added Afridi.

The campaign is being run by Pakistan and UNICEF. Aseefa, the younger daughter of President Asif Ali Zardari and assassinated ex-prime minister Benazir Bhutto, is also an ambassador for the cause.

“It’s my duty to help mankind as the Almighty has given me stature, so I am ready to do any social work which helps human beings,” said Afridi.

Local Taliban and Pakistani warlord Hafiz Gul Bahadur, whose loyalists are fighting the Americans in Afghanistan, have banned anti-polio vaccinations in the tribal region of Waziristan to protest against US drone attacks.

They say the drone strikes kill civilians and have condemned the immunisation campaign as a cover for espionage.

Pakistani doctor Shakeel Afridi was jailed for 33 years in May after helping the CIA find Osama bin Laden through a fake hepatitis vaccination programme.

Pakistan is one of just three countries where polio remains endemic, along with Afghanistan and Nigeria.

The highly infectious disease affects mainly the under-fives and can cause paralysis in a matter of hours. Some cases can be fatal.
