Who discovered the smallpox and cowpox vaccines?

Edward Jenner is the one who brought the vaccine idea to life. He noticed that milkmaids who got cowpox seemed protected against smallpox, so he tested whether a milder infection could confer immunity to the deadly one. In 1796 he inoculated a healthy boy with material from a cowpox lesion and later exposed him to smallpox; the boy did not develop smallpox. This showed that immunity could be achieved using a less dangerous virus, leading to the vaccination concept—the term comes from vaccinia, the cowpox virus. Jenner’s work contrasted with variolation, which used smallpox material and carried greater risk. The other names listed contributed to different areas—Anton van Leeuwenhoek in microbiology, James Blundell in blood transfusion, and William Occam in philosophy—so Jenner is the correct figure for discovering the vaccines.
