The virological characteristics
of SARS-CoV-2 KP.3.1.1
These results suggest that KP.3.1.1 has the potential to be predominant due to its higher infectivity and increased immune evasion. In particular, #S31del in spike, the common mutation in KP.3.1.1, LB.1 and KP.2.3, is likely to be a key mutation.
KP.3.1.1 (JN.1.11.1.3.1.1). This variant harbors these mutations.
KP.3.1.1 spike = KP.3 spike + S31del. 4/
