【正文】 疫苗種類、特點(diǎn)及核酸疫苗制備方法摘要：疫苗可分為減毒疫苗、滅活疫苗、亞基疫苗、遺傳改良活疫苗、遺傳改良亞基疫苗、抗獨(dú)特型疫苗、合成多肽類疫苗、核酸疫苗。免疫功能包括免疫防御、免疫穩(wěn)定與免疫監(jiān)視三者。當(dāng)機(jī)體處于正常狀態(tài)時(shí)，它對(duì)機(jī)體有益；在異常狀態(tài)下，也可損害集體。傳統(tǒng)疫苗有細(xì)菌培養(yǎng)、病毒培養(yǎng)、支原體培養(yǎng)、免疫血清制備等基本技術(shù)。現(xiàn)代疫苗以基因工程方法修飾疫苗。新技術(shù)下有核酸疫苗問(wèn)世。關(guān)鍵詞：疫苗、核酸疫苗、遺傳改良Abstract：Vaccine includes attenuated vaccine，inactivated vaccine，subunit vaccine，genetic improvement live vaccine，genetic improvement subunit vaccine，antiidiotype vaccine，synthetic polypeptide vaccine，nucleic acid vaccine. Immunity includes immunologic defense,immunologic homeostasis and immunologic surveillance. When the body is in normal, it is beneficial to body。while in the abnormal condition, it can also damage the collective. There are bacteria, viruses, and mycoplasma cultivation, the basic technology of serum immunization preparation in the traditional vaccines. Modern vaccine modified vaccine by genetic engineering. By the new technology to the nucleic acid vaccine has published.Keywords：vaccine ，nucleic acid vaccine，genetic improvement 一、疫苗的種類及特點(diǎn)疫苗，是指為了預(yù)防、控制傳染病的發(fā)生、流行，用于人體預(yù)防接種的疫苗類預(yù)防性生物制品。生物制品，是指用微生物或其毒素、酶，人或動(dòng)物的血清、細(xì)胞等制備的供預(yù)防、診斷和治療用的制劑。預(yù)防接種用的生物制品包括疫苗、菌苗和類毒素。其中，由細(xì)菌制成的為菌苗；由病毒
