在市场上常见的猪用疫苗中,按疫苗种类分类大致分为全病毒灭活苗、减毒活疫苗、基因工程苗(包括亚单位苗.载体疫苗,核酸疫苗)等,传统的疫苗是用全病毒,全知菌来制备,而基因工程疫苗是通过生物技术分析病毒.細菌的结构,找到能够发挥免疫保护作用的基因片段,将目的基目片段插入新的载体,使之充分表达,经純化后而制得的疫苗,純蛋白含量是评估基因工程疫苗貭量标准的指标之一。作为现代分子生物学和分子免疫学的一个主要发展方向,基因工程疫苗在猪群中的各大疾病的免疫预防方面发挥着越来越大的作用。2014年10月青岛易邦生物工程有限公司(以下称“青岛易邦”)研发的猪圆环病毒2型基因工程亚单位疫苗(易固净)上市,2017年正值易圓净上市三周年之际,本刊有幸采访到青岛易邦猪苗事业部总经理张丽宏女士,就易圆净的研发和三年来的销售情况进行了详細地了解!
Commonly used in the market for swine vaccines, vaccine categories are broadly divided into the whole virus inactivated vaccine, attenuated live vaccine, genetic engineering vaccine (including subunit vaccine. Vector vaccine, nucleic acid vaccine), the traditional vaccine is to use Whole virus, all know bacteria to prepare, and genetically engineered vaccine is the biotechnology analysis of viruses. Bacterial structure, to find the gene can play an immune protective effect of the fragment, the purpose of the target fragment inserted into the new vector, make it fully expressed, purified The resulting vaccines, pure protein content is one of the indicators to assess the standard of genetic engineering vaccine. As a major development in modern molecular biology and molecular immunology, genetically engineered vaccines are playing an increasingly important role in immunological prevention of major diseases in pig herds. In October 2014, the porcine circovirus type 2 genetic subunit vaccine developed by Qingdao Ebon Bioengineering Co., Ltd. (hereinafter referred to as “Qingdao Ebon”) was launched in 2017, On the occasion of the third anniversary, we have the honor to interview Ms. Zhang Lihong, the General Manager of Pig Industry Department of Qingdao YiBang, who has a detailed understanding of the research and development of YiYuanJing and the sales in the past three years!
