  What is already known about this topic? COVID-19 vaccines are highly effective against severe SARS-CoV-2–associated outcomes, including those caused by the Delta Variants.
  
  What is added by this report? As of January 8, 2022, during Omicron predominance, COVID-19 incidence and hospitalization rates in Los Angeles County among unvaccinated persons were 3.6 and 23.0 times, respectively, those of fully vaccinated persons with a booster, and 2.0 and 5.3 times, respectively, those among fully vaccinated persons without a booster. During both Delta and Omicron predominance, incidence and hospitalization rates were highest among unvaccinated persons and lowest among vaccinated persons with a booster.
  
  What are the implications for public health practice? Being up to date with COVID-19 vaccination is critical to protecting against SARS-CoV-2 infection and hospitalization.
