Well, the “vaccine” comes from “vaccinia, the Latin name of cow pox disease, and it comes from” Vacca “, the Latin word for” cow “, the animal which has been instrumental in developing the first vaccine against smallpox by Edward Jenner in Britain in 1796. Vaccinia was a milder form of smallpox that were cows.Details below.

Attractions in science: why it says the vaccine vaccine?

A disease that killed 400,000 people each year in Europe was smallpox. Twice as many survived, but remained with sequelae after contacting the disease. Edward Jenner noticed however that the contact form lăptărele related to smallpox, but weaker, namely bovine smallpox taken from cows, no more ill of smallpox. It is true that the bovine form of smallpox, and it was a disease that results in temperature, wounds on the body and so on. But not in death and after a few days away on their own person. After curing, the person and not remain immune to human smallpox, the deadly?

Edward Jenner tested this in 1796, when the liquid collected from the wounds of a smallpox lăptărese cattle and placed on the skin of a boy of just 8 years. He fell ill with smallpox bovine stayed in bed a few days but then recovered completely. When Edward Jenner attributed to a deadly dose of smallpox (!), But … child has had absolutely no symptoms.

Thus was created the first procedure of immunization against deadly diseases. And the procedure for inoculation with material from other diseases to become immune to a disease other was described by Edward Jenner “vaccination” from the word “vaccine” which in Latin means “taurine smallpox,” because “Vacca” in Latin which means “cow.” And now you understand why your.

Later, the great Louis Pasteur immunologist generalized this term not only to the substance obtained from the cow, but in general any substance which helps to immunization for other diseases.

The first vaccine against smallpox was created in 1796, and smallpox was eradicated as a disease of the Earth in 1977.
