新型传染性法氏囊病疫苗研究进展

摘要

In recent years, the traditional inactivated or attenuated vaccines could not provide enough protection because of the emerging of antigentic variant IBDV strains and very virulent IBDV strains (vvIBDV), which have been been increasing difficulty against prevention and cure of IBD. Therefore, the development of more effective and safe has become an urgent need for new vaccines. In this paper, new vaccines research for infectious bursal disease reviewed in recent years.%传染性法氏囊病（IBD ）病毒变异株及超强毒株的频频出现使IBD 常规疫苗的免疫失败不断发生。因此，发展更为有效、安全的新型疫苗己成为迫切需要。本文就近年来新型传染性法氏囊病疫苗研究进展作以综述。
