Cases and hospitalizations by vaccination status

Look at the dates and how much change there has been in the unvaccinated hospitalization rate versus the vaccinated. 30 per 100k compared with 2 per 100k currently. I think a lot of the change has to do with the study they did recently that found that an unvaccinated person who recovered had good protection against previous variants but that the protection is significantly reduced with this variant:
Controlling for vaccine status, age, sex, ethnicity, asymptomatic status, region and specimen date, Omicron was associated with a 5.40 (95% CI: 4.38-6.63) fold higher risk of reinfection compared with Delta. To put this into context, in the pre-Omicron era, the UK “SIREN” study of COVID infection in healthcare workers estimated that prior infection afforded 85% protection against a second COVID infection over 6 months. The reinfection risk estimated in the current study suggests this protection has fallen to 19% (95%CI: 0-27%) against an Omicron infection.
The Omicron variant largely evades immunity from past infection or two vaccine doses according to the latest Imperial modelling.
