The First Major Discoveries That Laid The Foundation For...

The first major discoveries that laid the foundation for technological advances in the world of vaccinations were that of Edward Jenner and Louis Pasteur. In 1796, Jenner took on smallpox. He had been informed that milkmaids seemed to be immune to the disease, however, upon further inspection he realized that the women all had a lesser form of smallpox, called cowpox, on their hands. He began to theorize that cowpox played a role as to why the women never contracted the deadly disease. To test his theory, he rubbed pus from a cowpox wound into a laceration of a young boy and then exposed him to smallpox. Weeks later, the boy still hadn’t contracted the more lethal disease, smallpox. He called this a vaccine, however, he had no idea as to why this was or what the connection was between the two diseases. As such, people of this age were skeptical to test the new vaccine. In 1885, Louis Pasteur decided to take on rabies. Well aware of Jenner’s studies, he began to create a vaccine from the spinal cords of infected rabbits. The method was first tested on a young boy who was bitten by an infected dog. Unknown if the vaccine was effective, the boy survived and there was now scientific evidence to back both theories. However, Pasteur, like Jenner had no idea as to why these methods worked. As the 20th century took off, technological advances in the field of medicine began to shed light as to why Jenner and Pasteur’s vaccines worked so well and it was their discoveries so earlyShow MoreRelatedThe Impact of Microorganisms on Human Affairs4185 Words   |  17 Pageseverywhere and have a large impact on the world. It all started when one of the most important discoveries in history was made in 1665. Englishman, Robert Hooke discovered â€Å"little boxes† or â€Å"cells† in a slice of cork through the microscope and explained that these were life’s smallest structural unit (Tortora et al, 2010). This event marked the beginning of the cell theory, that all living things are composed of cells.
