[Correspondence] #Antiviral humoral #immunity induced by #JN1 monovalent #mRNA #vaccines against SARS-CoV-2 omicron subvariants including #JN1, #KP311, and #XEC https://www.thelancet.com/journals/laninf/article/PIIS1473-3099(24)00810-7/fulltext?rss=yes
Our data suggest that the receptor-binding domain of JN.1 S can effectively induce antiviral humoral immunity against JN.1 subvariants and XEC comparable to the full-length JN.1 S.

Robust #antiviral humoral #immunity induced by #JN1 monovalent #mRNA #vaccines against a broad range of #SARS-CoV-2 #Omicron subvariants including #JN1, #KP311 and #XEC
Source: BioRxIV, AbstractAs of November 2024, SARS-CoV-2 Omicron JN.1 subvariants, such as KP.2 (JN.1.11.1.2), KP.3 (JN.1.11.1.3), KP.3.1.1 (JN.1.11.1.3.1.1), and XEC, a recombinant lineage between KS.1.1 (JN.13.1.1.1) and KP.3.3 (JN.1.11.1.3.3), have been circulating in several countries. To control…

Neutralizing #antibody #evasion of #SARS-CoV-2 #JN1 derivatives #KP3, #KP311, #LB1, and #XEC
Source: BioRxIV, AbstractThe emergence of SARS-CoV-2 variants poses ongoing challenges to vaccine efficacy. We evaluated neutralizing antibody responses against JN.1 and its derivatives (KP.3, KP.3.1.1, LB.1, and XEC) in healthcare workers who received seven doses of BNT162b2, including XBB.1.5 monovalent vaccine. In COVID-19-naive individuals, KP.3.1.1 and LB.1 showed…

#Impact of #JN1 #booster #vaccination on #neutralisation of #SARS-CoV-2 variants #KP311 and #XEC
Source: BioRxIV, {Excerpt} Conclusion Collectively, we found that the XEC S protein retains the ability to efficiently engage ACE2 and drive cell entry, although entry into Calu-3 lung cells was reduced. Both KP.3.1.1pp and XECpp were generally less well neutralised compared to JN.1pp, indicating elevated immune evasion. Importantly, JN.1-booster vaccination significantly…
