The World Health Organisation reported recently that the deaths from measles had surged in Pakistan in 2012 causing around 306 casualties and said there was a need to start an offensive to immunise children in the worst-hit areas of the country which has a poor health care system.
The outbreak of measles has been the severest in Pakistan's southern Sindh province with 212 deaths reported officially till today since last year.
"There is an inefficient state vaccination machinery resulting in a lack of coverage of the immunisation drive against measles," Dr S Akram, who works mostly in the interior of the Sindh province told PTI.
Akram is associated with HELP, a non-governmental organisation working to carry out immunisations in interiors.
Recently, WHO was also forced to suspend an anti-polio vaccine drive in Pakistan's biggest city Karachi after militants shot dead at least six health workers.
The anti-polio campaign has already run into problems in the Khyber Pakhtunkhawa province and its adjoining tribal areas where the Taliban and other militant outfits have denounced the anti-polio vaccine drive.

More than half of the children who have succumbed to measles died in the last three months of 2012.
Shah said the deaths due to measles was a reflection of the gross "mismanagement" that exists in the government-run routine immunisation for children.
He said only 65 per cent of the areas of Pakistan were covered by the present immunisation drive.
A Pakistani official of WHO also said that there was a big gap in the standard of immunisation coverage between provinces, districts and cities.
Measles, a contagious respiratory infection caused by a virus can cause lifelong disabilities including brain damage and blindness. It was a leading killer globally accounting for over 40 per cent of the 4.1 million deaths in 2002.
But as a result of major national immunisation drives, worldwide measles deaths fell from 871,000 in 1999 to an estimated 454,000 in 2004, a dramatic plunge of 48 per cent.
"It is unfortunate but other neighbouring countries like Afghanistan, Bangladesh, Nepal and India have succeeded a great deal in eradicating measles due to well managed immunisation drives which was missing in Pakistan," a leading specialist at a top private hospital said.
Sindh health minister Sagheer Ahmed said the government was alarmed by the situation and had recently launched a campaign to vaccinate 2.9 million children in affected areas.
