On 22 and 30 August a second person, condemned to death, with a plethoric constitution and of strong build was inoculated with blood. The first time in a fold of the left arm and in the right groin area, the second time in the opposite positions. On the area of the vaccination only the natural reddening and infections caused by the vaccination instrument appeared, nothing else. * * * * * “A third person condemned to death was inoculated with the fluid taken from a Plague Bubo in the groin and in the shoulder. This same person had dressed in the clothes of a plague patient 20 days previously and had contracted the plague with all its severe symptoms. The skin and tissue of this experimental subject remained refractory towards any absorption of the poison. Even when the inoculation with blood was repeated 8 days later, no disease resulted.” * * * * * _SMALLPOX_ In 1791, the teacher Plett of Holstein successfully vaccinated three of his landlord’s children in Starkendorf near Kiel. Later on when an epidemic occurred they did not contract the disease, while their brothers and sisters which had not been vaccinated fell sick. 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.
