"Anomalies and Curiosities of Medicine"

De Curco
introduced vaccination into Vienna, where its beneficial results
were displayed on a striking scale; previously the average annual
mortality had been about 835; the number now fell to 164 in 1801,
61 in 1802, and 27 in 1803. After the introduction of vaccination
in England the mortality was reduced from nearly 3000 per million
inhabitants annually to 310 per million annually. During the
small-pox epidemic in London in 1863, Seaton and Buchanan
examined over 50,000 school children, and among every thousand
without evidences of vaccination they found 360 with the scars of
small-pox, while of every thousand presenting some evidence of
vaccination, only 1.78 had any such traces of small-pox to
exhibit. Where vaccination has been rendered compulsory, the
results are surprising. In 1874 a law was established in Prussia
that every child that had not already had small-pox must be
vaccinated in the first year of its life, and every pupil in a
private or public institution must be revaccinated during the
year in which his or her twelfth birthday occurs. This law
virtually stamped small-pox out of existence; and according to
Frolich not a single death from small-pox occurred in the German
army between 1874 and 1882.
