    1. Kai Kupferschmidt. (2021, December 1). If you’re curious how likely #omicron is to have spread from South Africa or Botswana to different places, @DirkBrockmann and colleagues have done some interesting calculations based on the world aviation network from 08/2021 You can see that US seems a very likely destination https://t.co/OSnZ6ZNble [Tweet]. @kakape. https://twitter.com/kakape/status/1466107074585239568

    2. Kai Kupferschmidt. (2021, December 1). @DirkBrockmann That percentage number tells you “how likely an infected passenger from South Africa or Botswana travels to each country and exits the airport there”. So: “0.9% in Germany means that out of 1000 such individuals, 9 are expected to have Germany as their final destination.” [Tweet]. @kakape. https://twitter.com/kakape/status/1466107478807097354

    1. 🇺🇦 Meaghan Kall [@kallmemeg]. (2021, December 23). VACCINES Speaking of boosters, it’s not great news I’m afraid.

    1. Ali Ellebedy. (2021, December 30). We need those who are adept at #SciComm to explain that “Omicron” is sufficiently different from the original strain that was used to make the vaccine. Therefore, the definition of “fully vaccinated” will have to be updated, but that does not mean that the vaccines have failed.

Risk of reinfection in England with #Omicron was ~5.4 fold higher compared to #Delta The relative risk were 6.36 & 5.02 for unvaxxd & vaxxd cases—Implies protection against reinfection by Omicron may be as low as 19% [Tweet]. @KrutikaKuppalli. https://twitter.com/KrutikaKuppalli/status/1482074117742288898

    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. Dr Emma Hodcroft. (2022, January 28). Just to clarify some confusion about what “Omicron” is. “Omicron” has always applied to the whole family (BA.1-3—We’ve known about them all since late-Nov/early-Dec).
