We compared the abilities of the six internal RNA segments of two avian influenza viruses, A/Mallard/Alberta/88/76 (H3N8) and A/Mallard/NY/6750/78 (H2N2), to confer attenuation on wild-type human influenza A/Bethesda/1/85 (H3N2) virus in seronegative adult volunteers. Live avian-human influenza A reassortant virus vaccines derived from either avian virus parent were comparable in the following properties: safety, infectivity, immunogenicity, and genetic stability. Since the avian influenza A/Mallard/Alberta/76 virus offered no clear advantage as a donor virus, we will conduct our future evaluations on live influenza A virus reassortants derived from the more extensively characterized avian influenza A/Mallard/NY/78 virus.
我们比较了两种禽流感病毒A/野鸭/艾伯塔/88/76(H3N8)和A/野鸭/纽约/6750/78(H2N2)的六个内部RNA片段,在血清阴性成年志愿者中使野生型人甲型流感病毒A/贝塞斯达/1/85(H3N2)减毒的能力。源自任一禽病毒亲本的活禽-人甲型流感重组病毒疫苗在以下特性方面具有可比性:安全性、感染性、免疫原性和遗传稳定性。由于禽流感A/野鸭/艾伯塔/76病毒作为供体病毒没有明显优势,我们将对源自特征更广泛的禽流感A/野鸭/纽约/78病毒的活甲型流感病毒重组体进行未来评估。
