"The existence of any vaccines directly contradicts this point, since after all, a vaccine prevents you from ever getting the condition in the first place. Just think all the medical services we could sell if we got rid of the polio vaccine."My sister, her husband, myself and my spouse are all of a generation that didn't receive the polio vaccine, because it had been "cured". My niece and nephew both have polio. I had my daughter vaccinated for it.Polio is on the rise, because companies would rather make a profit on the cost of care, then eliminate the disease. I'm sure we're going to start seeing small pox outbreaks again for the same reason.
