Some northern states opposed to the immunisation of children against polio are committing an unforgivable offence against the innocent kids and humanity, the United Nations Children’s Fund (UNICEF) has declared. At the forefront of the opposition to the use of polio vaccine are Bauchi, Niger, Kano and Zamfara states. The Nigerian Supreme Council for Sharia NSCS (NSCS) set the stage for the controversy last year when it alleged that the exercise was a western plot to make women in the North infertile.
