Historical Perspective of VACCINE

     Many toxins, viruses, etc. were created at the beginning of the creation of life or even before. As a result, from the beginning of the creation of living beings until today, living beings are damaged, diseased, or dying due to the attack of all those substances. The organism tries to develop an immune system in its body against those foreign substances, by which it can protect itself from those substances or viruses. One way to artificially build this type of immunity in the body is through the use of vaccines.

     What is vaccination? The vaccine is a suspension of dead or inactivated and non-infectious disease-causing micro-organisms which, when introduced into the vertebrate body, act as antigens to induce specific immunity in the body.

     The young British physician Edward Jenner (1796) found out while treating, that woman who had previously suffered from cowpox never suffered from smallpox later on. For the test, Jenner collected a needle sample from a cow's rash and injected a small portion of the sample into an eight-year-old boy's arm through a scratch. Jenner saw that the boy's cut was swollen and the boy was slightly ill (These types of tests are currently prohibited without special permission).
Six weeks after this incident he cut the boy's arm in a similar manner with a thorn infected with smallpox. He observed that the boy was subsequently never affected by cowpox and smallpox. Vaccination is the process of increasing the body's immune system against diseases caused by bacteria by artificially introducing bacteria or germs into the body of vertebrates including humans.
The Latin word 'vacca' means 'cow'. Scientist Louis Pasteur coined the term 'vaccine' in honor of Jenner's discovery.
