"Publications by the World Health Organization show that diphtheria is steadily declining in most European countries, including those in which there has been no immunization. The decline began long before vaccination was developed. There is certainly no guarantee that vaccination will protect a child against the disease; in fact, over 30,000 cases of diphtheria have been recorded in the United Kingdom in fully immunized children."
Leon Chaitow, Vaccination and Immunization, p. 58. "Pertussis (whooping cough) immunization is controversial, as the side effects have received a great deal of publicity. The counter claim is that the effectiveness and protection offered by the procedure far outweigh the possible ill effects... annual deaths, per million children, from this disease over the period from 1900 to the mid-nineteen seventies, shows that from a high point of just under 900 deaths per million children (under age 15) in 1905, the decline has been consistent and dramatic. There had been a lowering of mortality rates of approximately 80% by the time immunization was introduced on a mass scale, in the mid-nineteen fifties. The decline has continued, albeit at a slower rate, ever since. No credit can be given to vaccination for the major part of the decline since it was not in use."
