We have posted data providing real-time measurement of human neutralizing antibody landscape to seasonal influenza.

Data explain spread of subclades K (H3N2) & D.3.1.1 (H1N1), identify subclade K subvariants w reduced neutralization, & can inform choice of strains for next vaccine.

In new study led by @bdadonaite.bsky.social, we show many influenza HAs (H5, H7, H9, H1, H2, H3) can use avian or human MHC-II to enter cells.

We then use novel combo of deep mutational scanning & cryoEM to define how H5 HA binds to avian MHC-II.
