In ancient India
and China ,
it was known that people could protect themselves from smallpox by taking scabs
from a victim, crushing them into a powder, and swallowing or scratching it
into the skin. This unsavoury sounding practice called ‘variolation’ was
prevalent in India
and slowly spread to the western world in around 1600 AD. The practice though
was not widely adopted, because there was a chance of accidently contracting
full-blown smallpox and dying. In 1774, a smallpox epidemic broke out in Dorset County , England . A prosperous farmer called
Benjamin Jesty, who lived in Dorset , was
worried for his family. Although unproven, it was a well known fact in the
farming community that milkmaids, who contacted cowpox, were never affected by
the deadly smallpox. Cowpox caused pustules on cow udders and reduced milk
production. It also caused pustules on milkmaid’s skin, along with fever and
headaches. But they would recover in a few days. Two of Jesty’s servants had
been infected with cowpox and despite caring for two boys, with small pox, they
never contracted smallpox. Jesty had this fact in mind and he decided to take a
leap of faith. He took his family to Farmer Elford’s pasture, which had a cow
with cowpox. Jesty then took his wife’s stocking needles, dipped its tip on an
open cowpox lesion and then inoculated his entire family with the infectious
cowpox material. Jesty’s family survived the epidemic and his two sons remained
free of smallpox for the rest of their lives. People viewed Jesty’s action of
mixing human and animal substances as “abomination” against God. He was
scorned, ridiculed and even pelted with stones. As a young boy, Edward Jenner
too had heard about cowpox protecting people from smallpox. In 1772, after
completing his medical training the 23 year-old Jenner was still intrigued by
the connection. Unfortunately no one had studied it and so Jenner began
collecting case reports of people who had been infected with cowpox. When he
presented his case study to his medical colleagues, they insisted that his
ridiculous idea was merely an old wives’ tale. Undiscouraged, Jenner took
matters in his own hands and on May 14, 1796 performed the first vaccination on
eight year old James Phipps. Jenner inoculated the boy with infectious cowpox
“matter” taken from the hand of a milkmaid named Sarah Nelmes, who had picked
up the infection from a cow named Blossom. Just like Benjamin Jesty, Jenner too
faced criticism and ridicule and his data was not accepted by the medical
community. In 1798, there was another outbreak of smallpox and Jenner
inoculated several children, and all of them survived the outbreak. Rather than
approach the medical community, Jenner published his findings in a
self-published 64 page paper, in which the word ‘vaccination’ was first used.
The practice of vaccination began to spread really fast and within a few years
vaccination was administered not only in England
but also throughout Europe and America .
Vaccination for small pox continued for years and on October 26 1977, a
hospital cook in Merka , Somalia became the last person to
be infected by small pox. Smallpox became the first disease to be completely
eliminated from the face of the earth.
