Edward jenner’s smallpox inoculation experiment was based on an observation by a dairymaid that she could not get smallpox because she had already had cowpox. how did jenner form his hypothesis from this observation?

He asked what would happen if he deliberately inoculated someone with cowpox fluid from another person. He tested several to see if they prevented smallpox. He observed the cows with cowpox before forming his hypothesis. He then drew a conclusion based on his result

Hope this helped! :3
