Mingora- At least 27 minors were admitted to hospital after getting measles vaccines in the Swat district of Khyber-Pakhtunkhwa, where health authorities were already struggling to remove misconceptions about polio vaccination.According to officials, measles vaccination was being provided in a private school of Swat valley when condition of 27 students became serious. The students were shifted to Sadu Sharif hospital in unconscious condition. "All the children were treated at the emergency ward. We don't know anything about the vaccines they were given," said medics. Earlier in July 2012, expired measles vaccines have claimed three lives in the Swat district of Khyber-Pakhtunkhwa.
