【热门产品推介】Research Grade Anti-RSV F/Fusion glycoprotein F0 (01.4B)
理想的RSV疫苗须诱导针对多个中和位点的高效价抗体,并将诱导突变毒株的可能性降至最低,最佳预防效果是否须同时诱导血清IgG、黏膜IgA和细胞免疫,尚不明确。安全性和免疫原性是RSV疫苗研发面临的主要挑战。

已有研究表明,很难设计一种适合所有目标人群的RSV疫苗,须根据不同人群的特点研制不同的RSV疫苗。减毒活疫苗、病毒载体疫苗、纳米颗粒疫苗、亚单位疫苗是目前处于临床研究阶段的主要疫苗类型。病毒非复制型RSV疫苗(如亚单位疫苗)针对孕妇以及其他非幼稚人群(大年龄儿童、老年人);6月龄以上RSV血清阴性儿童适合接种复制型疫苗(减毒活疫苗或载体疫苗)。目前,许多疫苗还处于临床前研发阶段,2020年Biagi等总结:目前有30余种候选RSV疫苗已进入临床试验阶段,其中儿童疫苗21种,包含14种减毒活疫苗、4种载体疫苗、2种颗粒疫苗、1种嵌合疫苗;老年疫苗9种,包含4种载体疫苗、3种亚单位疫苗、2种颗粒疫苗;孕妇疫苗4种,包含3种亚单位疫苗、1种颗粒疫苗。
