An English doctor by the name of Edward Jenner. He noticed that milkmaids got cowpox which was similar to smallpox, but much milder, and after a milkmaid had had cowpox, she did not get smallpox. So Dr Jenner tried to scratch the skin of volunteers with a needle dipped in to cowpox germs. The volunteer got a transient mild illness and did not get smallpox after vaccination.
When Dr Jenner's vaccine was shown to be so effective, vaccination against smallpox became compulsory. Smallpox is now almost entirely eradicated and most counties stopped making smallpox vaccination compulsory in the late 70s and early 80s.

Vaccination
Immunization against smallpox has, for centuries, been infection with live vaccinia virus.
A doctor named Jenner.
Edward Jenner developed vaccine against smallpox in 1798. He used cowpox virus containing fluid for the same.
The smallpox vaccine is an injection to prevent one from contracting smallpox. It has been used to help the body to develop immunity against the disease.
No. After you get a disease like smallpox, your body is able to develop permanent defenses against it. This makes you "Immune" to the disease. This is the principle on which vaccines work.

Edward Jenner was a medical doctor, surgeon and scientist. He is also called the "father of immunology" for his work in producing a smallpox vaccine. The smallpox vaccine was actually a cowpox variation but it did provide protection against smallpox.
Smallpox was one of the first sucess-stories of vaccinations. So many people had the vaccine that Smallpox mostly died out. It is now only found in laboratories, and maybe in some poorer countries.
Antibodies to cowpox virus
