When Edward Jenner began vaccinating for smallpox, he was not aware that he was ushering in a true miracle age. Smallpox was a dreaded and horrible disease that killed millions, and now it is gone, thanks to vaccination.In 1900, the average life expectancy in the U.S. was 47. In 2000, it was 77. Most of this incredible improvement was brought about by the development of childhood vaccines. Measles, whooping cough, and diphtheria all killed hundreds of thousands of children--no more, thanks to vaccines.
Yet scientific illiteracy threatens further progress. Anecdotal reports and misguided fears have lead to a resurgence of some childhood illnesses and many unnecessary deaths.
Stupidity and willful ignorance are not reasonable nor responsible in our day.
And for the developing world, vaccination holds one of its few hopes for a better future.
Thank you, Dr. Jenner, for your bravery and hope.
That is what I believe science is really about.
