昨天新發表了一篇研究結果
作者是倫敦國王學院 King's College London
結果把大家都嚇傻了....
1.原文連結:
https://www.medrxiv.org/content/10.1101/2020.07.09.20148429v1
2.原文內容:
Longitudinal evaluation and decline of antibody responses in SARS-CoV-2
infection
65個感染COVID-19的病人(59個住院 6個醫護)
抽血抽了三個月 追蹤抗體變化
超過95%的人都會產生抗體(63/65)
有兩個人沒抽到抗體就出院了
作者認為如果出現症狀十幾天後再抽應該還是會驗到抗體
幾乎所有人的IgG抗體 三個月內都會下降
有些人初始IgG本來就不高的
甚至會下降到基準值(baseline)
3.心得/評論:
作者承認沒辦法討論細胞免疫
(抗體免疫是B細胞 細胞免疫是T細胞)
所以抗體下降 並不等於 對病毒的免疫下降
或許COVID-19人體是靠T細胞在對抗
而不是只靠B細胞在產生抗體
這部分在這篇文章底下的討論就有人提出這點質疑
不過這篇文章還是提醒了科學界
1.群體免疫看來完全不可行
2.疫苗可能要需要定時boost
不在是打一次就終身好
可能需要一直定時追加
3.更有效的抗病毒藥還是有迫切發展的需要
股點了話大概就是
1.疫苗如果有做出來的疫苗股
買好買滿 可能真的是下一支微軟office
根本定期印鈔機
2.口罩大概五年內不會回到過去價格
不過口罩門檻這麼低的東西
我實在不看好口罩股
3.航空旅遊觀光業寒冬可能會更長=.=
我兒子小二
我本來預估下次帶他去日本可能已經是四年級
現在我悲觀的認為或許他小學畢業前都沒辦法在去日本了o.O
