SARS-CoV-2 #JN1 variant (#BA28611), arising from BA.2.86.1 with spike protein (S) substitution S:L455S, outcompeted previously predominant #XBB lineages by beginning of 2024. Subsequently, JN.1 subvariants including #KP2 (JN.1.11.1.2) & #KP3 (JN.1.11.1.3), which acquired additional S substitutions (eg, S:R346T, S:F456L, and S:Q493E) have emerged concurrently (appendix pp 19–20).2
