研究免疫反应的科学叫免疫学。免疫不仅与传染病有密切关系,而且与非传染病或一些过去病因不明的疾病也有关系。过去一直把免疫学看作是微生物学的一个分枝。现在对免疫及免疫学的认识比过去深得多,认为免疫是机体为保持内在环境的稳定,对内、外源性异物进行斗争而发生的生理、病理现象的总和,可发生或不发生自身组织损害。 The science of immune response is called immunology. Immunization is not only closely linked to infectious diseases, but also to non-communicable diseases or diseases whose past etiology was unknown. In the past have been immunology as a branch of microbiology. Immune and immunological awareness is now much deeper than in the past, that immunity is the body in order to maintain the stability of the internal environment, the fight against internal and foreign foreign body, the total physiological and pathological phenomena, may or may not occur Tissue damage.
