Who were the early pioneers in vaccinations?

Answer 1

Some well-known pioneers:

1. Louis Pasteur

   Pasteur wrote "the germs of microscopic organisms abound in the surface of all objects, in the air and in water." He figured out these microorganisms could be killed by heating liquid (55 C/130 F) for short periods of time, which is known as pasteurization, i.e., used for milk. With his work in microbiology, He showed that diseases (like rabies) could be prevented by vaccination (a term created by Pasteur!), that is, injecting an organism with weakened forms of the disease, thus opening up the field of Immunology.

2. Edward Jenner

   Jenner observed that for some odd reason milkmaids did not get smallpox. He speculated that the pus in the blisters they got from cowpox (they were around cows all day) protected them from smallpox.

   In 1796, Jenner tested his theory: He inoculated a young boy with the pus from cowpox blisters (he extracted from the hand of a milkmaid who had caught cowpox from a cow) and lo and behold! There we have our first smallpox vaccination!

Answer 2

Edward Jenner was a scientist in the 1700's and noticed that milkmaids normally did not get smallpox. He theorized that the pus in the blisters they got from cowpox protected them from smallpox. On May 14, 1796, Jenner tested his theory by inoculating a young boy with material from the cowpox blisters of the hand of a milkmaid who had caught cowpox from a cow. This produced a fever and some uneasiness but no great illness. See the related link for more information.
