‼️Does the updated XBB.1.5 vaccine protects against the SARS-CoV-2 variant JN.1 ? A short🧵
@EricTopol @kakape @ewencallaway @DrEricDing @PeterHotez @jbloom_lab @BenjMurrell @RajlabN @LongDesertTrain @PeacockFlu @siamosolocani @ACasadevall1 @MarionKoopmans @RobiVil
JN.1 is the fittest descendant of BA.2.86*, the “Pirola clan” as named by @TRyanGregory Image
At first @yunlong_cao used JN.1-pseudotyped VSV to show that sera from (BA.5+XBB)- or XBB-infected subjects poorly neutralize infection of Huh-7 cells (mean titers 65 and 24), & that JN.1 fully resists to sotrovimab (S309) but maybe not to the upcoming AZD3152 (Omi-42) monoclonal Image

With 4 great studies out so far in #Pirola and it’s 1st sublineage designated, it’s time to summarize findings, crosscheck predictions, solve discrepancies, & exhibit more tools. A🧵
@EricTopol @DrEricDing @TRyanGregory @ewencallaway @kakape @MarionKoopmans @florian_krammer
How fast is BA.2.86 spreading? (84 seqs so far). Variant seekers are reporting (@shay_fleishon, @LongDesertTrain, @OliasDave and @JosetteSchoenma paved the way), @RajlabN has a great time trend @HNimanFC has light-fast reporting and maps. @jampei2 has a Re model based on Denmark Image
How infectious is BA.2.86 for cells ? Data from @SystemsVirology and @yunlong_cao shows it’s not too bad in the current landscape Image

‼️SEP 3 UPDATE Spike convergent evolution in XBB.*
New FLip members: HK.8, HK.10, JJ.1.
HS.1.1 joins 456L+478R family
FL.1.5.1 recombined w/ “last of Cerberus” BQ.1.2.2
🧵
@RajlabN @LongDesertTrain @yunlong_cao @jbloom_lab @SystemsVirology @EricTopol @SolidEvidence @BarouchLab Image
This chart shows how common S:K478X acquisition has been so far in XBB* compared to former Omicron lineages… /2 Image
And the same is true for S:F456L, the propedeutic step to the S:L455F FLip first described by @yunlong_cao (see his preprint here: ) /3 biorxiv.org/content/10.110…
