Heterotypic immunity to influenza virus in ferrets operated against heterotypic influenza viruses but not heterologous viruses. Contrary to prior reports, the protection conferred lasted for at least 18 months. This type of immunity limited virus shedding but did not prevent infection. These results suggest that this phenomenon could play a role in determining the severity of infections caused by type A influenza viruses in humans.
雪貂对流感病毒的异型免疫作用于异型流感病毒而非异种病毒。与先前的报道相反,所提供的保护持续了至少18个月。这种免疫类型限制了病毒传播,但并未阻止感染。这些结果表明,这种现象可能在决定甲型流感病毒在人类中引起的感染严重程度方面发挥作用。
