serum 隻顯示1/3中和功能。serum作用主要是抗體？T cells作用不變？

All serum samples were able to neutralize the viruses but were about two-thirds weaker against the B1351 spike protein. However, the authors said that because the vaccines also produce other types of immune responses, such as from T cells, they may be more effective in real life than in the lab.

所有跟帖： 

• 沒錯啊，即便中和效價不如對原株的效價，還是有保護作用啊。其它疫苗更糟啊 -fuz- ♂ (0 bytes) () 03/25/2021 postreply 11:44:41

• serum作用主要是抗體？是不是serum含有抗體不含T細胞？ -huntridge- ♂ (0 bytes) () 03/25/2021 postreply 11:49:24

• 中和抗體可以用血清滴度測量；細胞免疫發生在個體內，很難在體外測試。總不能拉幾個人來打變異株吧，那太不人道了 -fuz- ♂ (0 bytes) () 03/25/2021 postreply 11:53:18
