WHO | 2024年南半球流感毒株信息已發布
流感不同于普通感冒,是由每年都在變異的最新(xīn)型流感病毒感染而發作(zuò),症狀也比普通感冒嚴重很(hěn)多(duō),會全身酸痛、咳嗽、流涕、發燒等,甚至可(kě)以直接導緻死亡,因此接種流感疫苗成為(wèi)預防流行病爆發的必要手段。
流感病毒變異性不确定,世界衛生組織(WHO)每年都會預測南北半球候選流感病毒,作(zuò)為(wèi)各疫苗企業生産(chǎn)疫苗的風向标。WHO會通過英國(guó)國(guó)家生物(wù)制品檢定所(NIBSC)來向全世界分(fēn)發流感病毒。
近日,WHO更新(xīn)了南半球2024年候選流感病毒株和相關抗原抗血清标準品:
Egg-based vaccines
• an A/Victoria/4897/2022 (H1N1)pdm09-like virus;
• an A/Thailand/8/2022 (H3N2)-like virus; and
• a B/Austria/1359417/2021 (B/Victoria lineage)-like virus.
Cell culture- or recombinant-based vaccines
