German report showing they still have very low omicron (omikron!) but rising, but nothing like at double rates seen elsewhere, re-enforcing that lockdown works.
One thing though
186 Patientinnen und Patienten waren ungeimpft, 4.020 waren vollständig geimpft, von diesen wurde für 1.137 eine Auffrischimpfung angegeben
186 patients unvaccinated, 4020 vaccinated of which 1137 boosted as well. So over 95% vaccination, this despite ~70% total vaccination. However I think the lockdown might impact this more than suggested as those still able to be out and about enough to be infected may well be more likely to be vaccinated? If not then prior infection does appear to be significantly better at preventing infection in Germany.
Mostly the news is that lockdown still does prevent omicron spread.
