用雪貂严重急性呼吸综合征(SARS)-CoV感染模型评价腺病毒疫苗的效力。使用来自表达刺突蛋白的人血清型5和黑猩猩衍生的腺病毒(人AdHu 5和黑猩猩AdC 7)的载体对动物进行异源初免-加强,然后用SARS-CoV鼻内攻击。接种疫苗导致病毒载量大幅降低,并防止未接种疫苗的动物出现严重肺炎。同样的初免-加强策略在恒河猴中有效地引发SARS-CoV特异性免疫应答。这些数据表明,基于异源腺病毒的初免-加强疫苗策略可以安全地刺激强烈的免疫力,这可能是完全保护免受SARS-CoV感染所需的。
A ferret model of severe acute respiratory syndrome (SARS)-CoV infection was used to evaluate the efficacy of an adenovirus vaccine. Animals were subjected to heterologous prime-boost using vectors from human serotype 5 and chimpanzee derived adenoviruses (human AdHu5 and chimpanzee AdC7) expressing spike protein followed by intranasal challenge with SARS-CoV. Vaccination led to a substantial reduction in viral load and prevented the severe pneumonia seen in unvaccinated animals. The same prime-boost strategy was effective in rhesus macaques in eliciting SARS-CoV specific immune responses. These data indicate that a heterologous adenovirus-based prime-boost vaccine strategy could safely stimulate strong immunity that may be needed for complete protection against SARS-CoV infection.
