Tibetian Statesman Wang Tan uses ground smallpox scabs to inoculate his one surviving child
The earliest attempts to confront the smallpox virus were based upon anecdotal observations and traditional folk medicine (Hopkins, 1983; Small & Small, 1996; Stein, 2011). In 1000 CE Tibet, it is recorded that the statesman Wang Tan had ground smallpox scabs administered by a nun with medical knowledge to his son in an attempt to save him from smallpox, which had already claimed the lives of his other children (Small & Small, 1996; CCP, 2012; Mercer, 1985).

Inoculation (variolation) used to prevent smallpox
Early inoculation, called variolation, from the time of China in 1000 CE to the late 1700’s involved the practice of using smallpox scabs from the skin of infected individuals and scraping it into the skin of healthy individuals (Hopkins, 1983; Mercer, 1985). Unfortunately, this often led to the healthy individual developing smallpox, though because there did appear to be some protective benefit, the practice had gained in popularity (Razzell, 1974 in Mercer, 1985) -
Smallpox Inoculation is introduced to the Western World
The practice of inoculation was not known to Western civilization until the 1720’s (Mercer, 1985). In 1718 Lady Mary Wortley Montague, wife of the British Ambassador to the Ottoman Empire, purportedly had her son inoculated after learning of the Eastern practice while in Istanbul.
