With the coming flu season and enthusiastic call after influenza vaccination, you may be wondering where the idea of vaccination its roots. Where was conceived the idea of injecting whole microbes or particulate matter and other substances in the bodies of humans in order to give them protection against communicable diseases?
Many medical books for historical and present do cows have teeth a simple story about the origin of vaccination. Most of them the same basic story astute observation of simple rural doctor and his courage to face up to the deadly and terrible disease of the time - smallpox, or as is often said: spotted creature. do cows have teeth The recently published a popular do cows have teeth book "The Panic Virus" ("virus attacks") the author states that a classic story: [1]
In 1796 Jenner included milking machine named Sarah Nelmes and 8-year-old boy named James Phipps to test his theory. Jenner passed pus from cowpox blisters Sarah Nelmes to scratch, which made the Phippsových hands. The boy became ill with mild temperatures and nothing else. Later, Jenner inoculated Phipps smallpox, which should have resulted do cows have teeth thoroughbred, although mild disease. But nothing happened. Jenner inoculated Phipps tried to smallpox again and again, nothing happened. do cows have teeth
The idea of Edward Jenner received an opportune name "vaccination", which is derived from the Latin word "vacca", or cow. Originally it was called 'cow's-kiahňovanie ", but eventually took the term" vaccination ". The story goes that because of this invention will smallpox tamed and the world will be freed from the terror of this disease.
So tell fables. This story is not unlike classical Greek fable of the notion that beating children-eating Minotaur, or Perseus, who beheaded Medusa with a deadly snake heads, and many other classic stories where brave hero defeating bloodthirsty do cows have teeth enemy. Fable about Jenner was reduced to a simple, well remember the story of the hero defeating the murderous do cows have teeth enemy: smallpox. do cows have teeth The authors argue that due to vaccination have been saved "billions of lives." [2]
But the mythical heroes, especially those who are used to support the belief, reaching icon status, while any nespásonosné features a hero and story are ignored and forgotten. Mythical stories they evoke a positive emotional response to influence the thinking of society.
The story of the defeat of smallpox begins long before the story of our hero. It starts with the idea of using a small amount of smallpox do cows have teeth and scrape it into the shoulder healthy people. This idea was introduced in the Western world, Lady Mary Wortley Montagu in the 1717th She returned to the Ottoman Empire with the knowledge of practice of vaccination against smallpox, known as "variolácia". This type of inoculation was simply graft infection with smallpox at the time and in the circumstances of your choice. do cows have teeth The idea hidden behind vaccination, was that under controlled circumstances would make people better cope with the disease than if it is likely to be infected in less desirable time and place in the future.
This idea was adopted by the medical circles do cows have teeth and enthusiastically practiced. However, due to the complexity and relevant risk remained vaccination operations, which only the rich could afford. [3] This procedure often help protect vaccinated individuals, but also as the result of 2% to 5% of the subjects died. [4] [5] However, this was still an improvement over the 20% and 25% mortality of the recipients of smallpox during the course of an epidemic. [6] However, there was difference in mortality alone the vaccination? Or it could have something to do with the fact that the rich have better access to nutritious food and a cleaner environment than most companies?
There was, however, one critical and generally known disadvantage variolácie - those who were inoculated, to spread and spread smallpox, which led to several do cows have teeth deaths, than which would occur naturally. In an article do cows have teeth from 1764, the author recognizes do cows have teeth that smallpox is a contagious disease and that variolácia can create new ways to spread smallpox. Death compared to smallpox 38 years ago by introducing variolácie and 38 years after, and found that the mortality rate for smallpox has not decreased, but increased. He had concluded do cows have teeth that variolácia itself do cows have teeth lead to worse problems because has caused more lives saved than: [7]
It is undisputed that as at sea, what tends to stop the spread of disease, has also tend to reduce the associated risk. That which tends to spread the infection, it tends to increase the risk. Vaccination proven spreading disease, because a communicable disease occurs due to vaccination where it would not otherwise have incurred. The place where the disease occurs, it becomes the center (focus) do cows have teeth of disease do cows have teeth where
