Polio is actually increasing in India, Nigeria, Afghanistan and Pakistan. Why? Because an anti-polio fatwa by anti-Western clerics forbid Pakistani children from immunizations, because the clerics are saying the vaccine is a conspiracy to make Muslims sterile. Ironically, it’s the clerics’ plans that would produce this result, as dead/paralytic kids don’t breed all that much.
