In the early 1900s an astute Indiana physician, Dr. W.B. Clarke, stated “Cancer was practically unknown until compulsory vaccination with cowpox vaccine began to be introduced. I have had to deal with two hundred cases of cancer, and I never saw a case of cancer in an unvaccinated person.”
There is a widely held belief that vaccines should not be criticized because the public might refuse to take them. This is valid only if the benefits exceed the known risks of the vaccines.
