#IDMastodon Analysis of the association between the new #SARSCoV2 variant EG.5 /‘#Eris’ & XBB #breakthroughinfection .BTI of XBB subvariants cannot efficiently induce antiviral #humoralimmunity against the infecting variants vs the BTI of previous #omicronvariants. clarification the characteristics of EG.5 (Eris) which is becoming increasingly prevalent around 🌎

the great majority of people infected with #SarsCoV2 recovered following asymptomatic infection or having only acute mild to moderate disease, with recovery occurring prior to the onset or peak of #humoralimmunity.The kinetics of infection with recovery in these #COVID19 cases, and that many cases are asymptomatic, underscore a major role for #innateimmunity in early control of #SarsCoV2 infection.

#IDMastodon #COVID19 : Efficacy of #antivirals & bivalent Boosters against #SARSCoV2 isolate CH.1.1 /#omicron CH.1.1 @thelancetinfdis . These results suggested although CH.1.1 effectively evades #humoralimmunity induced by bivalent boosters or natural infection, the #bivalentvaccine can enhance neutralising activities.
