What pertaining or relating to cattle

The term vaccine has two widespread uses in our language. We find one of them in the field of livestock to refer to everything belonging or relating to cattle, i.e. to the cows. For example, this portfolio has been manufactured with the finest raw materials in vaccines.

Substance which is inoculated to form antibodies and generating an immune response

And the other well used applications that has the word vaccine is found in medicine and refers to the organic substance or virus, conveniently prepared, which, applied to the body, will make this to react against it, preserving it from subsequent infections. I.e., the vaccine is a substance that is specially prepared and which will generate the formation of antibodies in the body that receives it to get a positive response from the immune system, which will be that the agency that receives the vaccine not spread virus which is inoculated him through the vaccine.
Basically, the vaccine consists of a preparation of antigens, which is a substance that will allow the formation of antibodies and has the ability to generate an immune response within the organism in which it is applied. This attack response allows the development of an immunological memory, which generally will produce permanent immunity from the disease.

The first vaccine was...

The first vaccine that recorded the history dates back to the year 1796 and says that it was created by the rural physician Edward Jenner, who discovered that the cowpox immunized persons suffer smallpox human, much more deadly and serious that the animals that suffer. From this first test, eventually appeared other vaccines that fortunately came to counteract the effect of other serious diseases such as rabies, in 1882, plague, in 1897, the tuberculosis in 1927, yellow fever in 1935, flu in 1945, rubella in 1970, chickenpox in 1974 , meningitis in 1978 and that of Hepatitis A, most recently in 1998, among so many others.

Composition of vaccines and types

Vaccines can be composed of bacteria or viruses, whether live or weakened, that they were created for this purpose. But vaccines may also contain inactive organisms or purified, from the first and these products become the four traditional types of vaccines.
Inactivated, harmful microorganisms that have been treated with chemicals or heat and have lost your danger (flu, cholera, bubonic plague, Hepatitis A). This type of vaccine is usually incomplete or of limited duration, so it will be needed more than one outlet. The attenuated live, on the other hand, are microorganisms that have expressly been cultivated under conditions in which lose their harmful properties. They usually have a longer-lasting immune response (yellow fever, measles, mumps). The toxoids are inactivated toxic components from microorganisms (tetanus, diphtheria). And Subunitarias, rather than introduce a microorganism dimmed or inactive integer within an immune system, a fragment of this creates the immune response (subunitaria Hepatitis B vaccine).

A milestone in biomedical research and health care

If doubt, vaccines, constitute a milestone in the research in biomedicine because without them it would have been impossible to eradicate very serious and life-threatening illnesses and also not was had have not prevented the spread of certain viruses or diseases. Health improved on a large percentage due to the emergence of the vaccine.
By this same is that it is so important that everyone comply with the immunization schedule, because in this way we will be preventing the spread of many diseases and of course adding to the health of the population in general.
From the first months of life, the people, we must be vaccinated and along our growth you must repeat doses or well implemented new vaccines to ensure good health.
It is very important that pediatricians medical inform parents concerning this issue and indicate their patients what should be the mandatory vaccination schedule.
It is recommended that children be vaccinated as soon as their immune system is trained to deal with artificial immunization a vaccine.
But in addition to this mandatory vaccination in infancy, it is also necessary that people give is vaccines when they leave travel to some parts of the world where there are still outbreaks of diseases such as yellow fever in parts of Africa and some parts of the North of South America.
It is also recommended that pregnant and elderly people get vaccinated against influenza, pneumonia, and against rubella pregnant women.
Worth noting is that in those places where the consciousness of parents not raw material and access to health is difficult, the State, to deal with bring vaccination campaigns.
