Prince Abdulaziz Bin Majed Bin Abdul Aziz, Emir of Madina, will personally administer the first two vaccines to one girl and one boy on Saturday as he launches the campaign for the eradication of polio in the region. The campaign, part of the nationwide drive to tackle polio, involves oral doses of vaccine, according to Abdul Razak Hafez of Madina's Health Directorate. “The first doses will be given out over a three-day period by medical staff, while the second round will be administered at primary health care centers across the region,” Hafez said.
