> For individuals who have had COVID-19 previously, the risk of reinfection with Omicron is significantly higher, relative to prior variants.
These numbers show (as one would expect) that prior infection makes you less likely to get Omicron, and that prior infection with more recent strains does so more effectively. (Which might be because they're more Omicron-like, or because the infection was more recent. I'm guessing more the latter.)
