隨著時間的推進，武漢肺炎病毒亦變異出不同品種。1059Please respect copyright.ＰＥＮＡＮＡ9iYy0nIym0

陸續亦有研究發現，武肺變異品種其躲避疫苗或感染武肺最初版本抗體的能力有所增強。1059Please respect copyright.ＰＥＮＡＮＡPwbdqD4gBg

（圖2）簡略來說，我們身體應對病毒入侵有著兩大招數，抗體及Cytotoxic T cell。1059Please respect copyright.ＰＥＮＡＮＡ7ZxpgL5hoo

抗體其中之一的功用是能夠阻礙病毒進入人體細胞，使細胞免受病毒感染。1059Please respect copyright.ＰＥＮＡＮＡdP3T1mG9ZY
1059Please respect copyright.ＰＥＮＡＮＡXNRr5G4Vvl
而Cytotoxic T cell其中之一的功用是殺滅已受病毒感染的細胞，情形如同是消防員前往滅火，把已發生的災害清除。1059Please respect copyright.ＰＥＮＡＮＡz8q0rk8maZ

（圖3）有研究拿取注射兩劑瑞輝人士三星期後的血液，發現抗體辨認武漢肺炎病毒(巴西變種)的能力約降低了三倍，但負責製造相應Cytotoxic T cell的能力，其沒有因為變種而有所減低。1059Please respect copyright.ＰＥＮＡＮＡxivDZSOmKz

儘管抗體的辨認能力減弱，但這並非等於疫苗如同是廢了一樣，皆因抗體的數量亦是重要的指標，其數量足夠的話大可彌補辨認能力的缺失。1059Please respect copyright.ＰＥＮＡＮＡ9jxKyEG4JS
打個比喻來說，假設我們有20元在手，就算不小心丟掉了3元，還有17元在手，可足以購買10元的蘋果日報。1059Please respect copyright.ＰＥＮＡＮＡf3esw08qbm

再加上疫苗促使的Cytotoxic T cell產生能力並沒有因變種而有所減弱，可見疫苗亦有其充足的防禦作用。1059Please respect copyright.ＰＥＮＡＮＡx8jFEjHTfX
