项目摘要
Avian influenza (AI) viruses of H5N1 and H9N2 subtypes cause severe losses in poultry and pose risks for zoonotic infections. Currently available inactivated vaccines against these viruses are produced in embryonated eggs and have several disadvantages. We have developed a novel live virus vector-based vaccine exploiting herpesvirus of turkeys (HVT) as vaccine vector. The vaccine was prepared in cultured cells, and a single dose of vaccine delivered into eggs before hatch or after hatch induced life-long immunity in vaccinated chickens. Vaccinated birds showed protection against both highly pathogenic AI and Marek's disease when challenged at six week post vaccination. This project will enhance potency and efficacy of the HVT-based AI vaccines that will protect birds at an early age (within three weeks of hatch). In addition, we plan to develop a trivalent vaccine that will protect vaccinated chickens against both H5 and H9 subtypes of avian influenza viruses and Marek's disease.
H5N1和H9N2亚型禽流感(AI)病毒造成家禽严重损失,并构成人畜共患感染的风险。目前可用的针对这些病毒的灭活疫苗是在含胚蛋中生产的,并且具有几个缺点。我们已经开发了一种新的活病毒载体为基础的疫苗利用火鸡疱疹病毒(HVT)作为疫苗载体。该疫苗在培养细胞中制备,并且在孵化前或孵化后将单剂量疫苗递送到蛋中诱导接种鸡的终身免疫。接种疫苗的鸡在接种疫苗后6周进行攻击时,显示出对高致病性禽流感和马立克氏病的保护。该项目将提高基于HVT的AI疫苗的效力和功效,以保护早期(孵化后三周内)的鸟类。此外,我们计划研制一种三价疫苗,可保护已接种疫苗的鸡只免受H5和H9亚型禽流感病毒及马立克氏病的感染。
