Detailed explanation-1: -Healthy people would inhale a powder made from the crusts of smallpox scabs in order to protect themselves from the disease. They might show mild symptoms, but they were usually resistant to any subsequent exposure. The practice was called inoculation.
Detailed explanation-2: -Early in the 18th century, variolation (referred to then as ‘inoculation’) was introduced to Britain and New England to protect people likely to be at risk of infection with smallpox.
Detailed explanation-3: -One of the first methods for controlling smallpox was variolation, a process named after the virus that causes smallpox (variola virus).
Detailed explanation-4: -In Asia, practitioners developed the technique of variolation-the deliberate infection with smallpox. Dried smallpox scabs were blown into the nose of an individual who then contracted a mild form of the disease. Upon recovery, the individual was immune to smallpox.
Detailed explanation-5: -The ancient practice of variolation (named for smallpox, also known as variola or ‘la variole’) was widely used in Asia and some parts of Africa.
Detailed explanation-6: -Variolation was the method of inoculation first used to immunize individuals against smallpox (Variola) with material taken from a patient or a recently variolated individual, in the hope that a mild, but protective, infection would result. Variolation is no longer used today.
