He drew a conclusion about dairymaids who got cowpox becoming immune to getting smallpox.
From the observation that dairymaids who had caught cowpox didn’t get smallpox, Jenner hypothesized that cowpox infection conferred protection against smallpox — a hypothesis he later tested experimentally (e.g., by inoculating a boy with cowpox then exposing him to smallpox).
