#Neutralization of #SARS-CoV-2 #KP1, #KP11, #KP2 and #KP3 by #human and murine #sera

Source: npj Vaccines, AbstractWe report SARS-CoV-2 KP.1, KP.1.1, KP.2 and KP.3 neutralizing antibody titers. They displayed increased immune evasion compared to JN.1, especially KP.1 and KP.3, for participants who experienced BF.7/BA.5.2 breakthrough infection or received bivalent (delta/BA.5) vaccine boosting. Second XBB sub-variants breakthrough infection enhanced the neutralization…
