The infectivity and immunogenicity of live attenuated A/Washington/897/80 cold-adapted reassortant virus vaccine was evaluated in seronegative (hemagglutination inhibition titer, less than or equal to 1:4) and seropositive (hemagglutination inhibition titer, greater than 1:4) adult volunteers. The vaccine was efficient in infecting seronegative volunteers (94%). Moreover, 51% of seropositive vaccinees were infected by the virus. After live virus vaccination, greater than 83% of both seronegative and seropositive vaccinees achieved a level of nasal wash antibody previously associated with resistance to infection with influenza A virus. These findings indicate that both seronegative and seropositive vaccinees can benefit from live virus vaccination.
在血清阴性(血凝抑制效价小于或等于1:4)和血清阳性(血凝抑制效价大于1:4)的成年志愿者中评估了减毒活A/华盛顿/897/80冷适应重配病毒疫苗的感染性和免疫原性。该疫苗能有效感染血清阴性志愿者(94%)。此外,51%的血清阳性接种者被该病毒感染。接种活病毒疫苗后,血清阴性和血清阳性接种者中均有超过83%的人达到了先前与甲型流感病毒感染抗性相关的鼻腔冲洗抗体水平。这些发现表明,血清阴性和血清阳性接种者均可从活病毒疫苗接种中获益。
