Here's the latest variant+mutation picture for BA.1 with the Spike R346K mutation, aka BA.1.1 or "OmiRick".

BA.1.1 was classified quite recently, and has not yet flowed out to databases and websites as a lineage.

That mutation is understood to give increased immunity escape
🧵

Canada, the USA and France are reporting the highest frequencies.

The Frequency is calculated for each country independently, comparing to all the recent samples sequenced in that country.

Linear and Log Y-axis presented - log axis helps compare growth rates.

Canada has recently displaced Switzerland in the top 5 countries (by BA.1.1 samples shared).

Here's the breakdown of the top Canadian provinces reporting BA.1.1. New Brunswick seems the epicentre.

Here's the breakdown of the top US states reporting BA.1.1.

The highest frequency is reported in Colorado.

Here's the next 5 US states reporting BA.1.1.

Ohio is reporting the highest lineage among this set of smaller states.

Here's the breakdown of the top French regions reporting BA.1.1.

Auvergne-Rhône-Alpes is reporting the highest frequency.

Here are the next 5 countries in Europe reporting BA.1.1.

Belgium, the Netherlands and Switzerland are reporting the highest frequencies.

The study discussed in this pre-print found:
"...the entire panel of antibodies [every combination of natural immunity and/or vaccine] was essentially rendered inactive against this minor form of the Omicron variant."
