The immune system (according to Wikipedia) is formed by a set of mechanisms that protect the infections organism by means of the identification and elimination of pathogenic agents. Because the pathogenic ones include from virus up to worms intestinal parasites, this task is extremely complex and the threats must be detected by absolute especificidad distinguishing the pathogenic ones of the cells and normal textiles of the organism. To it it is necessary to add the evolutionary capacity of the pathogenic ones that allows them to create ways of avoiding the detection for the immune system and of infecting the organism host. A ello hay que sumar la capacidad evolutiva de los patógenos que les permite crear formas de evitar la detección por el sistema inmunológico e infectar al organismo hospedador.

To be protected, the living organisms have developed several mechanisms to recognize and to neutralize pathogenic. Even the simple microorganisms — as the bacteria — possess a system of enzymes that protect them against viral infections. Other basic immune mechanisms evolved in the ancient cells eucariotas they remain today in its modern progeny: plants, fish, reptiles and insects. These mechanisms include péptidos antimicrobial called defensinas, the process of fagocitosis and the system of the complement. Nevertheless, the most sophisticated mechanisms developed more recently in common with the evolution of the vertebrates [1]. The immune system of the vertebrates — since that of the human beings — comprises several types of proteins, cells, organs and textiles, which interact in an elaborated and dynamic network. This most complex immune answer that is evident in the vertebrates includes the aptitude to adapt itself this way to recognize pathogenic concrete in more efficient form. The adaptation process believe immune memoirs and it allows to offer a more effective protection during future meetings with these pathogenic. This process of acquired immunity is the base of the vaccination. Otros mecanismos inmunológicos básicos evolucionaron en las antiguas células eucariotas permanecen hoy en sus descendientes modernos: plantas, peces, reptiles e insectos. Estos mecanismos incluyen péptidos antimicrobianos llamados defensinas, el proceso de fagocitosis y el sistema del complemento. Sin embargo, los mecanismos más sofisticados se desarrollaron más recientemente de forma conjunta con la evolución de los vertebrados[1] . El sistema inmunológico de los vertebrados —como el de los seres humanos— comprende varios tipos de proteínas, células, órganos y tejidos, que interactúan en una red elaborada y dinámica. Esta respuesta inmune más compleja que se manifiesta en los vertebrados incluye la capacidad de adaptarse para así reconocer patógenos concretos en forma más eficiente. El proceso de adaptación crea memorias inmunológicas y permite brindar una protección más efectiva durante futuros encuentros con estos patógenos. Este proceso de inmunidad adquirida es la base de la vacunación.
