Vaccination
In the years following 1770 there were at least six people in England and Germany (Sevel, Jensen, Jesty 1774, Rendell, Plett 1791) who had successfully tested the possibility of using the cowpox vaccine as an immunization for smallpox in humans. But Edward Jenner was the first who successfully performed the vaccination in 1796Jenner's Initial Theory: The initial source of infection was a disease of horses, called "the grease", and that this was transferred to cows by farmworkers, transformed, and then manifested as cowpox.
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.
The first vaccine was created by Edward Jenner in 1796. He developed the smallpox vaccine by using material taken from cowpox lesions, demonstrating that exposure to cowpox could provide immunity against smallpox. This groundbreaking work laid the foundation for the field of immunology and vaccination, ultimately leading to the eradication of smallpox.
Smallpox was on the First Fleet in the form of bottles of dried innoculation materials. Such material was used to protect people against smallpox before Jenner's vaccination became available. No case of active smallpox disease was reported during the First Fleet voyage. However a seamen from the First Fleet caught smallpox (from local natives) over a year after arrival at Sydney Cove.
The doctor who inoculated Catherine the Great against smallpox was British. His name was Thomas Dimsdale, and he was an English physician. Dimsdale performed the inoculation in 1768, making Catherine one of the first Russian leaders to undergo the procedure. This event helped promote the practice of vaccination in Russia.
Edward Jenner in 1796 used the cowpox virus (vaccinia) to confer protection against smallpox, a related virus, in humans. Prior to this use, however, the principle of vaccination was applied by Asian physicians who gave children dried crusts from the lesions of people suffering from smallpox to protect against the disease.
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.

He did not discover much about the actual disease, but he came up with the vaccine. the first EVER vaccine.
Vaccination is the method used to prevent diseases like smallpox by introducing a weakened or killed form of the pathogen into the body to stimulate the immune system to produce antibodies against it.
Vaccination effect of the small pox last for life time. You need to consider vaccinating the whole population against the small pox. It gives some protection against the HIV infection, probably.
