  Smallpox
This practice, called variolation, induced an active case in the recipient, but usually the case was less severe than if the disease had been contracted in the normal way (by inhalation as it turned out).
Variolation was introduced into England and the American colonies early in the 18th century.
The variolated person often became quite ill and the mortality rate, although only a fraction of that for people who contracted the disease in the normal way, was nonetheless appreciable.

In India, variolation took several forms, the most common of which was the application of scabs or pus from a person with smallpox to the intact or scarified skin of a healthy person (30).
She called it "ingrafting"; it was a procedure done by old women, who made four or five scratches or a slight puncture on the arm and introduced material taken from smallpox pustules from patients who had mild cases of the disease (19).
Two to three percent of variolated persons died of smallpox; became the source of a new epidemic; or developed other illnesses from the lymph of the donor, such as tuberculosis or syphilis (39).

Variolated persons were, after all, at some considerable risk of contracting a serious case of smallpox from the procedure, and there was even a 1% to 4% risk of actually dying from the procedure.
Edward Jenner himself was inoculated by variolation in 1757 at the age of eight.

The risk of death from variolation was around 2%, a risk but a considerable improvement on the death rate for uncontrolled infection.
There was still a risk of death, variolation could potentially spread the disease as inoculated people were temporarily carriers for smallpox and the greatest resistance came from the church who condemned the practice as heathen and immoral.
He was well aware of the practice of variolation and he was also aware of the belief in the rural community that infection with cowpox led to immunity against smallpox.

 Smallpox:
This method of immunization was named variolation and involved taking samples (vesicles, pus from pustules, or ground scabs) from patients in whom the disease had been benign and introducing this material into other persons through the nose or skin (28).
The technique of variolation was spread by the caravaners (merchants traveling by caravan to sell their wares); for these persons, protection against smallpox was obviously a great advantage.
Variolation became widespread in the colonies of New England and especially in the city of Philadelphia, and it contributed to the notable growth in population in the second half of the 18th century.

In China variolation was done by having people inhale dust that had been produced by crushing the dried scabs collected from the pock scars of people with variola.
Negligible, of course, to those who did not become seriously ill. In immunological terms, variolation relies on a phenomenon known as herd immunity; the more people in a community (the herd) who are immune to an infectious disease, the less chance there is for the disease agent to establish an full-blown epidemic.
Variolation was introduced into England in 1718 by Lady Mary Wortley Montague, spouse of the British Ambassador to Turkey, and the practice was used in England until the end of that century.

For centuries, variolation, a technique by which a healthy individual is inoculated with pus taken from a patient with smallpox, was employed in both the East and the West for the purpose of inducing natural immunity against the disease, long before vaccination with cowpox was introduced by Edward Jenner in 1796.
Mather was the foremost advocate of variolation in America, perhaps because the terrible disease had changed his own life so dramatically: two of his children and his wife succumbed to it.

If variolation is to be considered the current standard of treatment, then inoculation with cowpox did not seem to present any greater risk than inoculation with virulent smallpox.

 Issues in Medical Ethics
It is usually overlooked that variolation (direct introduction of smallpox virus- containing material to induce or increase immunity) antedated the birth of Christ and the Christian era.
However, it should be emphasized that the introduction of new approaches to the prevention or management or treatment of a given disease involves nothing short of heroism on the part of the experimental subjects who subject themselves to the new approach before its safety and benefit.
Although accurate data are not available, this led to the widespread use of variolation, particularly since accurate epidemiologic records of morbidity and mortality from variolation were not kept.

 Vaccines--How and Why?
Although the effects of variolation varied, ranging from causing a mild illness in most individuals to causing death in a few, the mortality and morbidity rates due to smallpox were certainly lower in populations that used variolation than in those that did not.
One person who experienced variolation as a child in the late 1700s was Edward Jenner, a young boy who survived the process and grew up to become a country doctor in England.
As a country doctor, Jenner noticed a relationship between the equine disease known as "grease" and a bovine disease known as "cow pox." He saw that farmers who treated horses with grease lesions often saw the development of cow pox in their cows, complete with blisters similar to those seen in smallpox infection.

While variolation could provide protection and prevent the terrible disfigurement a naturally occurring case of the disease almost inevitably caused in the Eighteenth Century, it was not without its drawbacks.
Variolation was introduced into Europe just as smallpox was undergoing a resurgence and increase in virulence.
One contemporary account described the situation: "When smallpox is epidemic, entire villages are depopulated, markets ruined and the face of distress spread over the whole country." In areas of central Europe in the Eighteenth Century a new born baby was not given a name until after he or she had experienced smallpox and survived.

Variolation was a form of smallpox inoculation in which scabs or pus from smallpox victims were powdered and inhaled or inserted under the skin to confer immunity.
This method of inoculation was centuries old already when it came to Europe from Asia around 1720.
Variolated persons suffered from a mild case of the disease (1 or 2% mortality), but could still infect others with full-blown smallpox (25 to 60% mortality).

variolation Early form of vaccination in which part of the lesions produced by smallpox were used to try and trigger immunity to the disease
The Chinese were the first to put this observation into practice through an early form of vaccination called variolation, which was carried out as early as the 10th century and particularly between the 14th and 17th centuries.
The aim was to prevent smallpox by exposing healthy people to matter from the lesions caused by the disease, either by putting it under the skin, or, more often, inserting powdered scabs from smallpox pustules into the nose (see picture, below).

Variolation is the practice of inhaling material from the dried pox scabs or inoculating this material directly beneath the skin.
This method was effective, but had the disadvantage of producing smallpox when the material was active and not providing full immunological protection in some recipients.

Interestingly, many Africans had practiced primitive variolation for centuries, and this slave population was far less likely to be stricken by the dreaded pox (1).
While knowledge of variolation for protection against smallpox grew from a great reservoir of medical folklore, its popularization in England and Europe is often credited to Lady Mary Wortley Montagu, a high-spirited and witty literary figure of the early 1700s.
