The experiments are great, but it cannot explain why XDV.1, a hyper-variant with mostly XBB and JN.1-Spike and without R346T, Q493E or 31del, wins against FLiRT, FLuQE, DeFLiRT and DeFLuQEs in China.

However, in those who received inactivated vaccines or were infected with BA.5/BF.7 before XBB/JN.1 infection, we observed much more similar neutralization results over variants. The recent KP.3.1.1 (S31del) showed the strongest immune escape ability.(7/
