Hi, we are Pablo and Bruno. We are going to present our project of the first vaccine. We are not going to talk all about the first vaccine. We are going to talk also about medicine. The first vaccine was discovered on May 14, 1796 by Edward Jenner to fight the smartpox.

Medicine has had a long-run evolution since prehistory. In prehistory, they used preparations made of plants, animals and minerals.
00:00:22
In the mid-19th century, the microbiologist Pasteur explained why the diseases didn't develop spontaneously.
00:00:32
Thanks to this discovery, sterilization techniques were introduced into the operating rooms of many hospitals.
00:00:42
During the First and Second World War, many nurses suffered blisters and cracks in their
00:00:50
hands for strongly washing their hands with cold water and soap, in order to avoid infections
00:00:57
when taking care of wounded soldiers.
00:01:04
The first blood transfusion attempts were made in the 17th century, the first being
00:01:07
in 1665 between two dogs. The four different types of blood are A, B, AB and 0, were discovered
00:01:13
in 1901 by Carl Laffsener.
00:01:24
Another rediscovery in medicine was the organ transplant in 1906, before that the anaesthesia
00:01:27
in 1946 or the DNA in 1969.
00:01:35
One of the most deadly diseases in developed countries was the diabetes.
00:01:41
To fight this disease, insulin was discovered in 1922 and commercialized one year later.
00:01:45
If we break a bone today, we should go to the hospital to have an X-ray played.
00:01:52
The X-ray was made by accident in 1995 by William Conrad.
00:01:59
her to our present time in 1971, a combined vaccine against the Maslis, the mumps and
00:02:06
the rubella was discovered by Maurice Hillman.
00:02:24
Thanks for listening.
00:02:28
I hope you like it.
