Small Pox and Polio diseases were significantly decreasing in numbers as sanitation and plumbing infrastructure was being built in the United States. If one was to compare all the regions where this occurred, these diseases were dropping off remarkably. The vaccine industry came out with their vaccines after these significant drops in small pox and polio were occurring. Then they took credit for it. In reality it was clean potable water, proper sanitation treatment of human waste and improved nutrition during these years. The polio vaccine killed and maimed more people than the disease itself. Good sanitation, clean potable water, and good nutrition provides the best defense against any disease because it supports a healthy and strong immune system. A healthy immune system is infinitely better than all the vaccines ever made. It renders them useless.
