國藥及科興是中國兩款滅活病毒疫苗。而科興數據其可信性之高,就連公開聲稱戴口罩便沒法說話的梁卓偉院長也怕怕唔敢打。479Please respect copyright.PENANA3g0hOts9AE

大概是因為中國頭兩款疫苗過於「聲名大噪」,其第三款疫苗康希諾疫苗的關注度則相對較為低。而事實上,康希諾(Cansino)的疫苗設計其實是跟牛津疫苗非常相似。479Please respect copyright.PENANAm59qkCPfw8

1.疫苗的主要成份為已被削弱複製能力且無害的病毒,內含武肺S蛋白的DNA資訊。479Please respect copyright.PENANApMRaQAtbr5
2. 病毒進入人體細胞。479Please respect copyright.PENANAFDvBg3Ctt8
3. 人體細胞利用病毒內含的武肺S蛋白DNA資訊,製作武肺S蛋白。479Please respect copyright.PENANAUucUhYVMXX
4.免疫系統的相關細胞辨認武肺S蛋白是為外來之物,因而製作相應的抗體。479Please respect copyright.PENANAv2kA6rhli0

(圖3)因為康希諾疫苗所用的是人類常見的感冒病毒,約4-6成的人早已擁有對抗這感冒病毒的抗體,因此病毒還沒能進入細胞之前(圖2的步驟2),便早已被自身的抗體攔截。479Please respect copyright.PENANAATIHwbyYGz

而牛津所用的是黑猩猩所搵到的感冒病毒,原理上人體並沒有對應的抗體,因此亦相對上更易進入細胞。479Please respect copyright.PENANA6io9JyF53D

以這方面來看,牛津疫苗的設計比康希諾技勝一籌。479Please respect copyright.PENANAuovkuHA0VG

最近Bloomberg (Ref3)表示Cansino疫苗的保護效率達65.7%,而它跟Johnson&Johnson的疫苗一樣,均是一次性的方式注射。479Please respect copyright.PENANABiwPRgej3V
