There are two licensed herpes zoster vaccines. One is a live vaccine (ZVL) based on an attenuated varicella-zoster virus (VZV). The other is a recombinant vaccine (RZV) based on the VZV glycoprotein E (gE) combined with AS01B, a multicomponent adjuvant system. RZV is superior to ZVL in efficacy, and differs from ZVL in that protection is not diminished by the age of the vaccinee and has not waned significantly during 4 years of follow-up. Immunologic studies demonstrated higher peak memory and persistence of T cell responses in RZV compared with ZVL recipients. RZV recipients also showed development and persistence of polyfunctional T cell responses. Taken together, we conclude that the immunologic data parallel and support the higher efficacy over time of RZV compared with ZVL.
有两种获得许可的带状疱疹疫苗。一种是基于减毒水痘带状疱疹病毒(VZV)的活疫苗(ZVL)。另一种是基于 VZV 糖蛋白 E(gE)与 AS01B 的重组疫苗(RZV),AS01B 是一种多组分佐剂系统。RZV 在疗效上优于 ZVL,与 ZVL 不同的是,疫苗接种者的年龄不会降低保护效果,并且在 4 年的随访中并未明显减弱。免疫研究表明,与 ZVL 受种者相比,RZV 受种者的记忆 T 细胞和持久 T 细胞反应更高。RZV 受种者还表现出多功能 T 细胞反应的发展和持续存在。综上所述,我们得出结论,免疫数据与 RZV 相对于 ZVL 的更高疗效平行且支持其更高疗效。
