The increasing number of reports of direct transmission of avian influenza viruses to humans underscores the need for control strategies to prevent an influenza pandemic. Vaccination is the key strategy to prevent severe illness and death from pandemic influenza. Despite long-term experience with vaccines against human influenza viruses, researchers face several additional challenges in developing human vaccines against avian influenza viruses. In this Review, we discuss the features of avian influenza viruses, the gaps in our understanding of infections caused by these viruses in humans and of the immune response to them that distinguishes them from human influenza viruses, and the current status of vaccine development.
禽流感病毒直接传播给人类的报告数量不断增加,凸显了采取控制策略以预防流感大流行的必要性。接种疫苗是预防大流行性流感导致严重疾病和死亡的关键策略。尽管在针对人类流感病毒的疫苗方面有长期经验,但研究人员在开发针对禽流感病毒的人类疫苗时仍面临若干其他挑战。在本综述中,我们讨论了禽流感病毒的特征、我们对这些病毒在人类中引起的感染以及与之不同的针对它们的免疫反应的理解方面的差距,以及疫苗开发的现状。
