New data from our lab @BarouchLab on the Neutralization Escape of BA.2.86, FL.1.5.1, EG.5.1, and XBC.1.6. We had a well-defined cohort of 66 participants, with people who did and did not receive bivalent mRNA vaccines. A thread🧵.
This was a massive effort from the @BarouchLab members, especially from @airisyc @jesslmiller17 @mrowe1625 @trisha_anand31 @CamilleRMazurek @BIDMC_CVVRTrial and the ever wonderful @bettekorber1!

We first looked at the nAbs induced by bivalent mRNA vaccines against BQ.1.1, XBB.1, and XBB.1.5 at baseline, 3-weeks-post boost and 3 months post boost. nAb levels peaked at week 3 post-boost, but waned over a period of time.
