Nigerian polio vaccine tests give 'all clear'
Laboratory tests by Nigerian scientists have dismissed accusations that the polio vaccine given in a mass immunisation campaign in the country is contaminated with HIV and anti-fertility hormones.
The World Health Organisation drive to rid the world of polio hit a major obstacle in October when immunisations were suspended in three regions in northern Nigeria due to rumours that the vaccine was laced with HIV and hormones to render women infertile.
Some Islamic clerics suggested the vaccine is part of a Western plot to depopulate Africa. However, test results from experts recruited by the Supreme Council for Sharia in Nigeria gave the all clear on Tuesday.
