81. (LV. 220) JENNER started from these premises. (Jenner, quoted from Paschen, K.Kr.U., Manual on pathological micro-organisms, T. VIII, 1, P821). In his first test, he inoculated with variola 16 persons who had suffered from cowpox previously. They did not fall sick.
In 1796, a milkmaid who suffered from a finger injury contracted an infection when milking a cow sick with cowpox. She developed a case of cowpox. With the contents of one pustule, Jenner vaccinated a boy. The boy developed typical vaccine pustules at the vaccination area of his arm. Two weeks later, Jenner carefully inoculated the boy on both arms with new pustule matter. No sickness ensued, and a second inoculation also was negative. Thus, clear proof was furnished that cowpox transmitted to human beings possessed the same protective value as that produced in animals.
However, another epidemic was necessary before Jenner’s success was recognized. In this instance he inoculated 6 children directly from the cow. They developed a slight infection, and a subsequent inoculation failed.
The success of Jenner’s experimental infections on human beings have resulted in a blessing for all mankind inasmuch as his fundamental experiments on human beings have caused the extermination of variola in all countries that have compulsory vaccination.
