Solution
The finding that was essential for Edward Jenner's vaccination process is "Exposure to a milder disease form may produce immunity."
Edward Jenner is known as the founder of immunology. His major contribution to medicine was the development of the smallpox vaccine. He discovered that milkmaids who had contracted a milder disease called cowpox did not get smallpox. Jenner hypothesized that the cowpox protected the milkmaids against smallpox.
To test his hypothesis, he inoculated a boy with cowpox. After the boy recovered, Jenner exposed him to smallpox, and the boy did not get sick. This experiment was the beginning of the development of modern vaccines. So, the concept that exposure to a milder form of a disease may produce immunity was essential for Jenner's vaccination process.
