ISLAMABAD - The spokesperson of the Prime Minister House Thursday clarified that the premier announced no deadline for eradication of polio.

The spokesperson said a day earlier it was reported that the prime minister had vowed to eradicate polio from Pakistan within six months and that he would personally review the progress of the polio programme every fortnight.

However, the PM House spokesperson denied the statement, saying that the PM never gave any deadline for the eradication of polio.

The Prime Minister, however, has directed the provinces to take extensive measures against polio eradication during the months of November and April when polio virus cases were relatively low.

Nawaz furthermore directed the relevant authorities to take initiative to vaccinate every child on an emergency basis.

Pakistan is one of only three countries in the world where polio remains endemic but efforts to stamp it out have been badly hit in recent years by attacks on immunisation teams.

Some 59 people including health workers and police providing security have been killed in militant attacks on polio vaccination teams since December 2012.

The militants allege polio vaccination is a cover for espionage or Western-conspiracy to sterilise Muslims.
