Regarding the wide-spread epidemics that decimated populations at the beginning
of the 20th century, modern research indicates that epidemics such as diphtheria,
pertussis, and tetanus died a natural death in the 1940's and 1950's without
the assistance of vaccines. How else could the epidemics have ceased in
Europe as well where there was no mass vaccination program as in the United
States? Studies today point to the fact that the decline of infectious
diseases such as diphtheria, pertussis, and tetanus, are due to better
health conditions, better nutrition, and an abatement of the overcrowded
conditions in metropolitan areas.
