Amid anthrax vaccine's success, Pasteur introduced rabies vaccine (1885), the first human vaccine since Jenner's smallpox vaccine (1796). On 6 July 1885, the vaccine was tested on 9-year old Joseph Meister who had been bitten by a rabid dog but failed to develop rabies, and Pasteur was called a hero.

A transitional period began in the late 1850s with the work of Louis Pasteur. This work was later extended by Robert Koch in the 1880s. By the end of that decade, the miasma theory was struggling to compete with the germ theory of disease. Viruses were initially discovered in the 1890s.
1868 – Busch discovered that a sarcoma patient being surgically intervened to remove the tumor, after being exposed to a patient suffering from erysipelas, got a skin infection and her tumor disappeared. He inoculated some other cancer patients with many successes. [7] [4]
He realised that he had discovered a new form of virus and later coined the term "bacteriophage". [23] [24] Between 1918 and 1921 d'Herelle discovered different types of bacteriophages that could infect several other species of bacteria including Vibrio cholerae. [25]
Readily visible alterations of the skin surface have been recognised since the dawn of history. Among the first to take an interest in skin diseases were the Mesopotamian peoples, who sought to understand the reasons for these problems, often resorting to explanations rooted in religion, astrology and divination, and were the first to observe and define various dermatopathies.
