A common misconception about vaccines purports that they are the primary reason why infectious disease rates saw a rapid and steady decline throughout the early-to-mid 20th century. But an honest look at the figures reveals that diseases like polio, typhoid, measles, and tuberculosis were already in significant decline long before vaccines were ever even invented, this being the result of improved hygiene and diet.

Data compiled by the National Health Federation (NHF), and relayed by Cynthia A. Janak of RenewAmerica.com, tells the real story about how virtually every major infectious disease of the 20th century was already on its way out long before its associated vaccine came onto the scene. This fact is clearly illustrated in these powerful visual graphs created by NHF that contain vital statistics from official U.S. public health records.
