A three-day anti-polio campaign kicked off across Sindh on Monday to meet the target of immunising over 2.24 million children under the age of five. The campaign has been launched by the Expanded Programme on Immunization (EPI), Sindh, which has mobilsed 21,000 lady health workers, 2,200 vaccinators and other health workers to visit door to door to administer polio drops to children across the province. The teams are supported by paramedics drawn from public and private sector health care centres while volunteers, associated with relevant NGOs and CBOs, have also been engaged. Sindh EPI sources said the team members were fully trained and well-versed in their jobs and had been advised not to immunize any child suffering from diarrhoea. In such a case, the child should be visited again after his recovery from the disease. The teams have been asked to see that no child was denied the right of this strong immunity against polio, said the sources.
