2020年流感季即将到来,喷鼻剂型流感疫苗Flumist或担当重要角色

2020-08-14 Allan MedSci原创

FluMist是一种喷鼻剂型流感疫苗,经鼻腔给药,是首个喷鼻剂型四价流感疫苗,可用于2至49岁的人群。

流感病毒是一种造成人类及动物患流行性感冒的RNA病毒,在分类学上,流感病毒属于正黏液病毒科,它会造成急性上呼吸道感染,并借由空气迅速的传播,在世界各地常会有周期性的大流行。流行性感冒病毒在免疫力较弱的老人或小孩及一些免疫失调的病人会引起较严重的症状,如肺炎或心肺衰竭等。从历史上看,季节性流感疫苗包含3株流感病毒株:A型流感病毒(H1N1)、A型流感病毒株(H3N2)、B型流感病毒株。

FluMist是一种喷鼻剂型流感疫苗,经鼻腔给药,是首个喷鼻剂型四价流感疫苗,可用于2至49岁的人群。FluMist疫苗能够预防甲型HINI、H3N2菌株、1或2个B型流感病毒。阿斯利康今日宣布,将在即将到来的流感季将第一批Flumist四价疫苗发送到美国。

美国疾病控制与预防中心(CDC)最近强调了在2020年流感季中流感疫苗接种率的重要性,以期减轻医疗保健系统的压力。如果在此期间COVID-19持续流行,针对流感的疫苗接种可以减轻医疗保健系统的负担。

阿斯利康还提高了Flumist的产量,比先前计划增加了25%以上。阿斯利康美国呼吸与免疫学高级副总裁Mina Makar说:“阿斯利康长期以来一直致力于保护公共健康,鉴于COVID-19的大流行,今年至关重要。为此,阿斯利康提高了生产能力并加快了疫苗开发”。
