...death rate has been cut in half? from 2% to 3% before 1900 to less than 1.2% now. In 1900 more than 16 of 100 babies died before they were one year old. Now only 7 of 100 die. By teaching the public to use typhoid-paratyphoid vaccines and diphtheria antitoxins and toxin-antitoxins mortality in these diseases has been...
Currently there are slightly less diphtheria, infantile paralysis, measles and typhoid in the U. S. than at this period last year, and slightly more meningitis, scarlet fever.

At the same period there were 676 deaths from influenza and pneumonia, much less than last year...

Until 1894 there was no exact method of curing diphtheria. That year the German, Emil A. von Behring, progressing along research lines which Louis Pasteur and Robert Koch had opened, discovered that the poisons which the diphtheria germ gave out stimulated, if injected into an animal, antitoxins in the animal's blood. Such antitoxins, injected into an active case of diphtheria, counteracted the effects of the toxins, cured the disease...
Later Dr. Theobald Smith, of the Rockefeller Institute, found that if a little diphtheria toxin were added to antitoxin the mixture would immunize animals against the disease. At once Dr. William Hallock Park, director of New York City's health department laboratories, and his associate, the late Dr. Abraham Zingher, began to immunize children with the toxin-antitoxin mixture. That mixture is what the "healthmobiles" were administering last week. Three to six months are necessary before immunity is established...
