Edward Jenner, an English country doctor from Gloucestershire,
administers the world’s first vaccination as a preventive treatment for
smallpox, a disease that had killed millions of people over the
centuries.
While still a medical student, Jenner noticed that milkmaids who had
contracted a disease called cowpox, which caused blistering on cow’s
udders, did not catch smallpox. Unlike smallpox, which caused severe
skin eruptions and dangerous fevers in humans, cowpox led to few ill
symptoms in these women. On May 14, 1796, Jenner took fluid from a
cowpox blister and scratched it into the skin of James Phipps, an
eight-year-old boy. A single blister rose up on the spot, but James soon
recovered. On July 1, Jenner inoculated the boy again, this time with
smallpox matter, and no disease developed. The vaccine was a success.
Doctors all over Europe soon adopted Jenner’s innovative technique,
leading to a drastic decline in new sufferers of the devastating
disease.
In the 19th and 20th centuries, scientists following Jenner’s model
developed new vaccines to fight numerous deadly diseases, including
polio, whooping cough, measles, tetanus, yellow fever, typhus, and
hepatitis B, and many others. More sophisticated smallpox vaccines were
also developed and by 1970 international vaccination programs, such as
those undertaken by the World Health Organization, had eliminated
smallpox worldwide.
