This family just arrived from Pakistan with all their possessions packed in the truck – food, firewood for the winter, clothes, furniture and their cow. In October, over 31 000 returnee children were given the oral polio vaccine (OPV) and over 12 000 received injectable inactivated polio vaccines (IPV) and measles vaccines with WHO support. At this first point of entry at Torkham border, also called the “zero point”, over 50 000 children have been vaccinated with OPV since July this year by vaccination teams supported by the Ministry of Public Health, WHO and UNICEF.
