New from today's @UKHSA report is the finding that Omicron has faster vaccine effectiveness waning vs symptomatic infection than Delta (N for Moderna small) https://t.co/viVjY37rNQ which is a replication of what has been seen in Israel @BarakRaveh

In neutralization assays, @BalazsLab observes only a 4-fold or 6-fold reduction in titer going from wild-type to Omicron after booster relative to 43-fold or 122-fold after initial mRNA vaccine series (https://t.co/EuHC1fuHWP). 4/14

71.9% of cases in London with specimens from 13 December were Omicron. Overall London cases are already reaching the maximum values ever seen in the pandemic.

Under existing control measures, we project a wave of infections resulting from Omicron that exceeds the January 2021 levels, for all four scenarios. In the optimistic scenario, hospital admissions are projected to remain below Jan 2021 levels.

I wanted to share one more figure from the #Omicron pre-print that I think offers some additional support for the idea that mRNA boosting doesn't just increase the total neutralizing response but instead "broadens" it to enable Omicron neuralization:

This graph shows relationship between time, viral load and transmissibility - and why Sensitivity against PCR looks horrible, even if the test is 100% sensitive to catch infectious people. The infectious period is days. PCR is not specific for this & stays pos for weeks 10/

I've redrawn this concept here. We have viral abundance on the x-axis in arbitrary units of 0% to 100% and population immune pressure on the y-axis also in arbitrary units. Viral adaptation is plotted by color and is just abundance × immune pressure. 4/19

Grenfell et al. 2004 (https://t.co/1uq4qZvP2f) lays out the conceptual foundations for thinking about this problem. This figure is a bit hard to parse, but basically vaccination will increase population immunity and move rightward on the x-axis. 2/19
