COVID-19 Incidence and Death Rates Among Unvaccinated and Fully Vaccinated Adults with and Without Booster Doses During Periods of Delta and Omicron Variant Emergence 25 U.S. Jurisdictions, April 4December 25, 2021. Over the study period, age-adjusted VE against COVID-related hospitalization was relatively steady, from 91.9% to 95.3%. The fall in the share of deaths that are among unvaccinated people could also be explained by changes in the unvaccinated population. That means about 78.5% of the new confirmed COVID cases were among the unvaccinated. Average weekly incidence rates and rate ratios are provided by age group, primary series vaccine type, and overall; overall and vaccine-specific rates were standardized by age, according to the enumerated 2000 U.S. Census age distribution.

High Intent mothers had younger children overall than Already Vaccinated mothers (41.9% of High Intent vs. 18.2% of Already Vaccinated had an 11-year-old child, p<0.001). But by January 2022, as we showed in an analysis posted on the Peterson-KFF Health System Tracker, about 4 in 10 deaths were vaccinated or boosted. The age-standardized IRR for cases in unvaccinated versus fully vaccinated persons was 13.9 during AprilMay and progressively declined to 8.7 during June, 5.1 during JulyNovember, and 3.1 during December, coinciding with the periods of Delta emergence, Delta predominance, and Omicron emergence, respectively. The added benefits of booster doses were especially prominent among persons aged 5064 and 65 years. More transmission can also lead to more deaths. From other data, we know there continue to be more overall deaths than there were before the pandemic (excess deaths).

In all jurisdictions, local health authorities review data to determine whether the death was associated with COVID-19 (through a review of vital records, cause of death, and/or other public health investigations or data sources), though methods vary by state or jurisdiction. Analysis periods were determined based on variant proportion estimates in the United States. Age-specific vaccine administration data were used for incidence rate denominators; numbers of unvaccinated persons were estimated by subtracting the numbers of fully and partially vaccinated persons from 2019 U.S. intercensal population estimates. A continuity correction assumed at 5% of each age group and jurisdiction would always be unvaccinated (i.e., fully vaccinated coverage 95%).
