Abstract

Despite the growing use of poxvirus vectors as vaccine candidates for multiple pathogens and cancers, their innate stimulatory properties remain poorly characterized. Here we show that the canarypox virus-based vector ALVAC induced distinct systemic proinflammatory and antiviral cytokine and chemokine levels following the vaccination of rhesus monkeys compared to the vaccinia virus-based vectors MVA and NYVAC. These data suggest that there are substantial biological differences among leading poxvirus vaccine vectors that may influence resultant adaptive immune responses following vaccination.

摘要

尽管痘病毒载体作为多种病原体和癌症的疫苗候选物的使用日益增加,但它们的固有刺激特性仍未得到很好的描述。在这里,我们表明与基于牛痘病毒的载体 MVA 和 NYVAC 相比,基于金丝雀痘病毒的载体 ALVAC 在恒河猴接种后诱导了不同的全身性促炎和抗病毒细胞因子和趋化因子水平。这些数据表明,领先的痘病毒疫苗载体之间存在着实质性的生物学差异,这可能会影响接种后的适应性免疫反应。
