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.

2
00:00:22,420 --> 00:00:32,420
Medicine has had a long-run evolution since prehistory. In prehistory, they used preparations made of plants, animals and minerals.

3
00:00:32,420 --> 00:00:42,420
In the mid-19th century, the microbiologist Pasteur explained why the diseases didn't develop spontaneously.

4
00:00:42,420 --> 00:00:50,420
Thanks to this discovery, sterilization techniques were introduced into the operating rooms of many hospitals.

5
00:00:50,420 --> 00:00:57,420
During the First and Second World War, many nurses suffered blisters and cracks in their

6
00:00:57,420 --> 00:01:04,420
hands for strongly washing their hands with cold water and soap, in order to avoid infections

7
00:01:04,420 --> 00:01:07,420
when taking care of wounded soldiers.

8
00:01:07,420 --> 00:01:13,420
The first blood transfusion attempts were made in the 17th century, the first being

9
00:01:13,420 --> 00:01:24,760
in 1665 between two dogs. The four different types of blood are A, B, AB and 0, were discovered

10
00:01:24,760 --> 00:01:27,920
in 1901 by Carl Laffsener.

11
00:01:27,920 --> 00:01:35,920
Another rediscovery in medicine was the organ transplant in 1906, before that the anaesthesia

12
00:01:35,920 --> 00:01:41,019
in 1946 or the DNA in 1969.

13
00:01:41,019 --> 00:01:45,019
One of the most deadly diseases in developed countries was the diabetes.

14
00:01:45,019 --> 00:01:52,019
To fight this disease, insulin was discovered in 1922 and commercialized one year later.

15
00:01:52,019 --> 00:01:59,019
If we break a bone today, we should go to the hospital to have an X-ray played.

16
00:01:59,019 --> 00:02:06,019
The X-ray was made by accident in 1995 by William Conrad.

17
00:02:06,019 --> 00:02:24,539
her to our present time in 1971, a combined vaccine against the Maslis, the mumps and

18
00:02:24,539 --> 00:02:27,620
the rubella was discovered by Maurice Hillman.

19
00:02:28,159 --> 00:02:29,319
Thanks for listening.

20
00:02:29,520 --> 00:02:30,479
I hope you like it.
