Hold on second, I'm confused!

How can your immediately prior trend plot for Europe show cross-over with XFG in mid-December, yet this next one shows XFG at 40% and both NB.1.8 & BA.3.2 at 30% each??

Something amiss here? (Even if it is only my comprehension!)

All prior trends appear to change *dis-continuosly* at start of Jan 2026, which makes me worry data-lag is complicating most recent trends? So, taking conservative position, am mentally cutting at Jan-1st with BA.3.2 at 20% & rising, XFG falling, and NB rising gently. @josetteschoenma.bsky.social

Any chance you could tell us the full list of amino acid mutations present in the XGA Spike?

And how do you know it is "fast"?

Thanks.

I'm on BlueSky at last!
