Result: In addition, some changes in the RBD region, including V367F, Q409E, Q414E, I468F, I468T, Y508H, and A522V, were observed to be more susceptible to neutralization mediated by mAbs.

---

Result: It is worth mentioning that some variants including F338L, V367F, I468F, I468T, and V615L (Figure 5B) were even more sensitive to the convalescent sera compared with reference strain, whereas more variants were found to be resistant to the convalescent sera.
