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。533Please respect copyright.ＰＥＮＡＮＡGqs1jvvUPX

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。533Please respect copyright.ＰＥＮＡＮＡST12jaUxz2

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。533Please respect copyright.ＰＥＮＡＮＡOReDo08jEg
2. 病毒進入人體細胞。533Please respect copyright.ＰＥＮＡＮＡqpx4PIECTm
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。533Please respect copyright.ＰＥＮＡＮＡlIDkgMfqKq
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。533Please respect copyright.ＰＥＮＡＮＡOXyTZth2KU

（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。533Please respect copyright.ＰＥＮＡＮＡdAuF79eUcy

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。533Please respect copyright.ＰＥＮＡＮＡGLrgpCrvs3
533Please respect copyright.ＰＥＮＡＮＡqsZMX0Cwep
以這方面來看，牛津疫苗的設計比康希諾技勝一籌。533Please respect copyright.ＰＥＮＡＮＡfrlZEYDyqY

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。533Please respect copyright.ＰＥＮＡＮＡ2gm4iFNtGe
