The 7-day moving average of deaths is at the Delta peak. Now averaging more than 2k deaths a day.
Over 150k people are hospitalized. A pandemic record.
Over 26k people in the ICU. Higher than the Delta peak.
If you don't think vaccines and boosters matter look at the difference between the UK and US this Omicron wave. Mind you the UK's Omicron wave is about 1-2 weeks ahead of the US's and still has substantially lower hospitalizations and deaths. Look especially at how low ICU hospitalizations are in the UK.
The US has 62.6% of its population fully vaccinated. Only 25.2% boosted. The UK has 71.7% of its population fully vaccinated. 54.9% boosted.
