#Virological characteristics of the #SARS-CoV-2 #KP3, #LB1, and #KP23 #variants, Lancet Infect Dis.: https://www.thelancet.com/journals/laninf/article/PIIS1473-3099(24)00415-8/fulltext?rss=yes
JN.1 subvariants such as LB.1 (JN.1.9.2.1) and KP.2.3 (JN.1.11.1.2·3), which convergently acquired a deletion at the 31st position in S (Ser31del) in addition to the aforementioned substitutions, have emerged and spread as of June, 2024 (appendix pp 12–13).

Our results suggest that S #substitutions convergently acquired in #JN1 #subvariants contribute to immune evasion, & increase their Re when compared to parental JN.1. LB.1 & KP.2.3 exhibited higher pseudovirus #infectivity & more immune resistance than KP.2. Data suggest that S:S31del is critical to exhibit +infectivity, +immune evasion, & potentially contributes to increased Re.
