In the last decade the European Union has experienced serious outbreaks of certain O.I.E. list A diseases such as foot-and-mouth disease, classical swine fever and avian influenza. These diseases have been controlled and eradicated by means of culling and destroying a very large number of animals, which has been very expensive and has raised ethical questions. In accordance with existing rules, emergency vaccination has also been applied under certain circumstances, but its use has often been hampered by the impossibility of distinguishing vaccinated but healthy animals from the infected ones and by its negative impact on the trade of the vaccinated animals and their products. Marker vaccines and suitable accompanying discriminatory tests may overcome these problems and be used as additional eradication tools, where appropriate. Provisions on the use of these tools have already been introduced in the legislation of the European Union.
在过去十年中，欧盟经历了某些世界动物卫生组织（O.I.E.）A类疾病的严重爆发，如口蹄疫、古典猪瘟和禽流感。这些疾病通过扑杀和销毁大量动物得以控制和根除，这一过程成本高昂，并引发了伦理问题。根据现有规定，在某些情况下也采用了紧急疫苗接种，但由于无法区分已接种疫苗但健康的动物和受感染动物，以及其对已接种疫苗动物及其产品贸易的负面影响，其使用往往受到阻碍。标记疫苗和合适的配套鉴别检测方法可能会克服这些问题，并在适当情况下用作额外的根除工具。欧盟立法中已经出台了关于使用这些工具的规定。
