In the 1720s what were people being inoculated against?
small pox, they would be injected with a small dose of a mild version of the disease.

What did Edward Jenner do in 1776?
inoculated several people with the pus from cow pox blisters and found that they developed immunity to small pox. Cow pox is not dangerous

the royal society refused to print Jenner's work so he paid to print pamphlets explaining his work

1979
The World Health Organisation (WHO) announced that small pox had been wiped out
8 of 17
Opposition to Jenner
thought it was wrong to give people and animals disease, interfered with gods plans, doctors lost money when the government offered vaccination free, some doctors didn't vaccinate people properly so it didn't work
9 of 17
Jenner's importance
his work proved that scientific methods could lead to a disease being wiped out. Saved the lives of millions
10 of 17
Jenner had success but what were some key downsides?
he didn't know why it worked, the link between small pox and cow pox was unique so didn't lead to other vaccinations, other diseases were still killing people
11 of 17
What breakthrough was announced in 1861?
Louis Pasteur published his germ theory explaining that microbes in the air (germs) caused decay
12 of 17
What did Robert Koch do?
linked bacteria to disease. Identified the specific microbe that caused anthrax in sheep, also the microbes causing TB and cholera. Discovered that chemical dyes stained bacteria which made them easier to study under a microscope
13 of 17
After work in 1879 what did Pasteur's team discover?
that a weakened version of a disease causing microbe could be used as a vaccine to create immunity from that disease
14 of 17
Pasteur and Koch's importance
their work meant the true cause of diseases had been found. These techniques could identify other microbes causing diseases and then develop vaccines to prevent and treatment to cure.
15 of 17
How did both Pasteur and Koch publishing their findings help?
they could use each others findings to help further their own investigations
16 of 17
How come Pasteur and Koch's findings didn't solve everything immediately?
took time to identify specific microbes so prevention and treatment was not immediately possible. The causes of some diseases (genetic conditions) were still unknown
