一项评估接种 H5N1 流感疫苗或未接种 H5N1 流感疫苗的成人一次或两次加强疫苗接种的安全性和免疫原性的研究
一项评估使用 MF59 佐剂、细胞培养衍生的 H5N6 流感疫苗接种一次或两次异源加强疫苗接种的安全性和免疫原性的 2 期随机研究,该疫苗已接种 MF59 佐剂、细胞培养衍生的 H5N1 流感疫苗或未接种疫苗
这是一项针对大约 300 名接受 2 剂 aH5N1c 或安慰剂并在 <65 岁队列中完成父母研究 V89_18 的成年人进行的 2 期、随机、多中心研究。 该研究调查了两次初免剂量的 MF59 佐剂 H5N1 细胞培养衍生疫苗 (aH5N1c),然后间隔 3 周接种一或两次 MF59 佐剂 H5N6 细胞培养衍生疫苗 (aH5N6c) 是否会引发对所用抗原的免疫反应用于在第一次和第二次异源加强疫苗接种后进行初免 (H5N1) 和加强 (H5N6)。
在父研究 V89_18 中接受 2 剂 aH5N1c 的合格受试者以 1:1 的比例随机接受两次 aH5N6c 疫苗接种,间隔 3 周(第 1 组)或在第 1 天接种 aH5N6c 疫苗并在第 22 天接种生理盐水安慰剂(第 2 组)。 在父母研究中接受安慰剂的合格受试者将接受两次 aH5N6c 疫苗接种,间隔 3 周(第 3 组)。 第二次接种疫苗后,将对受试者进行大约 6 个月的安全性和抗体持久性监测。 每个科目的总学习时间约为 7 个月。
