1) The Balmis Expedition was a three-year mission that set off from La Coruña, Spain in 1803 with the goal of vaccinating thousands in the Americas against smallpox. 2) They transported the smallpox vaccine across oceans using a "cold chain" method of keeping it cold with ice and plastic boxes to preserve it. 3) The vaccine was transported by infecting children with cowpox pustules and propagating the disease from child to child as a way of preserving the vaccine across long distances.


 Name: Edward Jenner
 Born: 17th of May 1749, in Berkeley, Gloucestershire

3. BALMIS

 The Balmis Expedition was a three-year mission to
the Americas with the aim of vaccinating thousands
against smallpox. Vaccination, a much safer way to
prevent smallpox.
 The Balmis expedition set off from La Coruña on
30th November 1803. It may be considered the first
international health-care expedition in history.


 The name of vaccine comes from cow because he
discovered the smallpox through a young boy that
works with cows

 Jenner decided to test this empirical
idea of ​inoculating healthy people with cowpox to confer
immunity against the dreaded disease.
 On May 14th, 1796 he extracted pus from a pustule on the
hand of Sarah Nelmes, a milkmaid who had contracted
smallpox from his dairy cow, and inoculated a healthy 8 year
old boy named James Phipps.
 The young boy developed a mild illness between the 7th and
the 9th day. A vesicle formed at the points of inoculation,
which disappeared without any complication. On July 1st, he
inoculated the boy with the dreaded smallpox, but he didn’t
fell sick. THE VACCINE HAD BEEN DISCOVERED.
