Jenner And Smallpox

  1. 1. Smallpox: The fight begins against infectious diseases. Mr McDonald
  2. 2. What we will learn today: <ul><li>Why was smallpox so deadly. </li></ul><ul><li>Who was Edward Jenner. </li></ul><ul><li>What was his theory? </li></ul><ul><li>What was the significance of his idea. </li></ul>
  3. 3. Smallpox <ul><li>In the eighteenth century, smallpox was a killer disease. </li></ul><ul><li>The victims who contracted the disease had frightening symptoms. </li></ul><ul><li>The symptoms were a high fever, sores over the body and when the disease spread to the organs it was a certain death. </li></ul><ul><li>People who survived were terribly scarred. </li></ul>
  4. 4. Inoculation <ul><li>One idea to combat smallpox was inoculation. </li></ul><ul><li>This was when people deliberately infected themselves with a weakened version. </li></ul><ul><li>It did not often work. </li></ul>
  5. 5. Edward Jenner (1749 – 1823) <ul><li>Doctor from rural Gloucestershire. </li></ul><ul><li>Studied under a great doctor (James Hunter) in scientific observations. </li></ul><ul><li>Jenner noted that an old tale that milk maids did not catch smallpox appeared to be true. </li></ul>
  6. 6. The Theory in Practice <ul><li>In 1796, Jenner decided to test out his theory by experimentation. He heeded the words of his mentor John Hunter “don’t think – try the experiment.” </li></ul><ul><li>He needed two things for his experiment. </li></ul><ul><li>Someone who has never had either cowpox or smallpox. </li></ul><ul><li>And the diseases </li></ul>
  7. 7. The experiment <ul><li>Sarah Nelmes , milkmaid had cowpox matter taken from her hand and placed via a cut into James Phipps, an 8 year old. </li></ul>
  8. 8. The experiment <ul><li>The boy caught cowpox and was ill. Six weeks later, he was given smallpox by Jenner. </li></ul><ul><li>He had no symptoms – he was vaccinated. </li></ul><ul><li>The term Vaccination comes from Vacca meaning cow – Blossom the cow was famous! </li></ul>
  9. 9. Reaction <ul><li>Not everyone welcomed it. </li></ul><ul><ul><li>Some people thought that they would turn into cows </li></ul></ul><ul><ul><li>Others argued that as Jenner did not know why it worked they feared it would not. </li></ul></ul><ul><ul><li>Doctors who got rich by inoculation did not like it. </li></ul></ul>
  10. 10. Reaction to smallpox vaccine
  11. 11. Long term reaction <ul><li>By 1800, 100,000 people had been vaccinated. </li></ul><ul><li>Napoleon vaccinated his entire army in 1805. </li></ul><ul><li>In 1980, smallpox was deemed to have been eradicated by the WHO (World Health Organisation). </li></ul>
