BREAKING🔔 Here I want to quickly report our new results from G2P-Japan🇯🇵 before the preprint publication. We have elucidated the virological characteristics of SARS-CoV-2 KP.3.1.1 - a progeny of JN.1. Please RT🔥 1/

BREAKING🔔 A new study from G2P-Japan🇯🇵 is out at bioRxiv @biorxivpreprint. We elucidated the virological characteristics of SARS-CoV-2 KP.2 - a progeny of JN.1. Please RT🔥 1/ biorxiv.org/cgi/content/sh…
Cf. This is KP.2 (aka JN.1.11.1.2). In spike, KP.2 = JN.1 + S:R346T, S:F456L & S:V1104L).
We remember that R346T was observed in BQ.1.1 and XBB lineages, while F456L is a hallmark of EG.5 lineage. 2/
Transmissibility/fitness (Re): molecular phylogenetic-epidemic dynamics modeling led by Jumpei @jampei2 and Kaho showed that the Re of KP.2 is ~1.2-fold greater than that of JN.1. 3/
