preventions

• small pox - before vaccines


  INNOCULATION - infected person deliberately infected a healthy person

  problems = it increased the amount of people who had the virus - some people spread it, some people died
• Edward Jenner - cowpox


  1798 - milkmaids get cowpox - they don't get small pox

  tested on an 8year old - work -> tested it on 23 people = worked

  1798 - Vaccinations
• edward Jenner - vaccinations


  1798 - paliment gave him £30,000 to open a vaccination clinic

  1852 - gov made them compulsory

  initially they were opposed - your deliberately giving yourself a cow disease, jenner couldn't prove why it worked, dangerous(people mixed up smallpox and cowpox)
• vaccines further developed


  pasteur - specific microbes could be isolated then vacinated

  1829 - weakend strands of chicken cholera -> stopped chicked getting infected

  antibodies

  Koch + Behring - inspired by Pasteur to find vaccines for humans
