When Jenner introduced vaccination he knew nothing of the infectious agents that cause disease: it was not until late in the 19th century that Robert Kock proved that infectious diseases are caused by microorganisms, each one responsible for a particular disease, or pathology. We now recognize four broad categories of disease-causing [[microorganism]]s, or [[pathogen]]s: these are [[virus]]es; [[bacteria]]; pathogenic [[fungi]]; and other relatively large and complex eukaryotic organisms collectively termed [[parasite]]s.

The discoveries of Koch and other great 19th century microbiologists stimulated the extension of Jenner's strategy of vaccination to other diseases.
