    1. Meaghan Kall. (2022, February 17). BA.2 risk assessment New this week is upgrading Immune Evasion—Amber 🟨 from low to moderate that BA.2 is antigentically different to BA.1 Unsurprising given the mutation profile, with BA.2 slightly more immune evasive than BA.1 on neuts studies https://t.co/n6DWtiRaNH [Tweet]. @kallmemeg. https://twitter.com/kallmemeg/status/1494100170195312646

    1. Alastair Grant. (2022, February 16). Samples likely to be BA.2 (SGT positive in TaqPath data) now make up 34% of COVID cases in England. The proportion has roughly doubled in a week. That represents a growth in absolute numbers of BA.2, even if overall infections are falling at the same rate as reported cases https://t.co/LNr5baChby [Tweet]. @AlastairGrant4. https://twitter.com/AlastairGrant4/status/1493880986660225024

    1. Ulrich Elling. (2022, January 12). While #Omicron BA.1 leads the race, the little sister BA.2 is catching up in numbers. They are rather different with likely functional implications. BA.2 might be more immune evasive in RBD, less in NTD. And due to reduced mutation load in NTD maybe different fusion properties?

    1. Mike Honey 💉💉💉. (2022, January 27). Here’s the latest variant picture for Australia. BA.1 (Omicron) is still very dominant. The new sub-lineage BA.1.1 (with the Spike R346K mutation) is significant, but not growing rapidly.

    1. Prof. Christina Pagel. (2022, January 31). Update on growth of Omicron subvariant BA.2 in England from Wellcome Sanger data. Growing in all regions. The main Omicron variant we’ve had so far is BA.1. There is then its child BA.1.1 with an extra mutation and its brother BA.2 which is pretty different to BA.1. 1/2 https://t.co/iVxrf01P4o [Tweet]. @chrischirp. https://twitter.com/chrischirp/status/1488127760291799041
