Although rare today, cowpox was widespread in 18th-century Europe, where it was common knowledge that milkmaids who had been infected with cowpox — which is generally mild — were then immune to the far more deadly smallpox.
By 1800, cowpox vaccinations (the word "vaccine" is from the Latin word for "cow") were commonplace, primarily because they caused fewer side effects and deaths than did variolation with smallpox itself.

His thesis "that the Cow-pox protects the human constitution from the infection of the Small-pox" was tested by vaccinating patients with fluid from pustles of cowpox-infected patients and then showing that these subjects were immune to smallpox.
This was a critical observation as it made it possible to obtain a continual supply of vaccine - this because cowpox infection in cows was sporadic and rare.
Even when the source of the vaccine was from true cowpox exudates, some reported failures could be attributed to degradation of the vaccine through improper storage and bacterial decomposition.

During the late 18th century, English folklore and some dairy-maids believed that if they caught cowpox, they would be immune to smallpox.(43) Cows are sometimes infected with a rash on their udders that can be transmitted to dairymaids when they milk the animals.
Jenner now insisted that these men were immune to smallpox, and that children would forever be protected from the disease if they were injected with cowpox after the cow was infected with the rancid secretions from horses' heels.
He carefully discriminated it from plain cowpox, which, he admitted, had no protective virtue.(50) But the public was appalled by Jenner's recommendations.

 NOVA Online | Bioterror | Making Vaccines: Smallpox
To create this vaccine, you begin with another virus that is similar to the smallpox virus, yet different enough not to bring on the smallpox disease once it enters your body.
The smallpox vaccine is a live vaccine; the cowpox viruses it contains will invade cells in your body, multiply, and spread to other cells in your body, just as the smallpox viruses would.
Then, if cowpox or the similar smallpox ever enters the body, the immune system will quickly get rid of the invaders.

 Spurious cowpox
Spurious cowpox, he explained, wasn't meant to describe irregularities on the part of the cow, but rather certain quirks in the action of cowpox on the part of the vaccinated.
Jenner at once asserted that the Cowpox in such instances must have been spurious, for Smallpox after genuine Cowpox was impossible; and Spurious Cowpox was thenceforward freely used to baffle inquirers and to account for failures.
Genuine Cowpox was said to be harmless —it was the Spurious that was ineffective or worked mischief; and the Inoculators plied the terror of Spurious Pox against Vaccination.
