The smallpox vaccine was developed by Edward Jenner, an English physician. He noticed that dairywomen who had caught cowpox - a related disease - did not catch smallpox. So he inoculated people with weakened cowpox, their bodies built up the antibodies to cowpox which then also protected them against smallpox.Cowpox is known as Variolae Vaccinae (vacca = cow in Latin) and hence the name.
Catherine the Great was in at least two wars against Turkey.
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.
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.
In the spring of 1721, the people of Boston were alarmed by the news that there were several cases of smallpox in town. They knew that the disease could spread like wildfire and that a great many people would suffer or die from the dreadful illness. Cotton Mather, a religious leader from Boston, had read about a new process that could provide a defense against the killer disease. It was called inoculation, and involved putting infected matter from a smallpox sore into a cut made in a healthy person's skin. Nearly all physicians in the community opposed the inoculation of healthy people, because the process actually gave those inoculated a milder case of the disease. They saw it as a means of spreading the already disastrous epidemic among even greater numbers of people. Finally, however, Mather and a few of his followers won out. While thousands fled to the countryside and others lay suffering and dying, they proceeded to inoculate many of the townspeople. By the time the epidemic was over, 240 persons had been inoculated and only 6 of them had died. Thanks to the scientific interest of Cotton Mather, a new defense against smallpox had been found.

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.
Both Catherine of Siena and Catherine of Sweden are the patron saints against miscarriages.
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.
