Dataset and data visualization details:
These data were posted on November 22, 2021 and reflect cases and deaths with a positive specimen collection date through October 2, 2021. These data will be updated monthly. Please note that these provisional data are subject to change.
Vaccination status: A fully vaccinated person had SARS-CoV-2 RNA or antigen detected on a respiratory specimen collected ≥14 days after completing the primary series of an FDA-authorized or approved COVID-19 vaccine. An unvaccinated person had SARS-CoV-2 RNA or antigen detected on a respiratory specimen and has not been verified to have received COVID-19 vaccine. Excluded were partially vaccinated people who received at least one FDA-authorized vaccine dose but did not complete a primary series ≥14 days before collection of a specimen where SARS-CoV-2 RNA or antigen was detected.
Deaths: A COVID-19–associated death occurred in a person with a documented COVID-19 diagnosis who died; health department staff reviewed to make a determination using vital records, public health investigation, or other data sources. Rates of COVID-19 deaths by vaccination status are reported based on when the patient was tested for COVID-19, not the date they died. Deaths usually occur up to 30 days after COVID-19 diagnosis.
Participating jurisdictions: Currently, these 24 health departments who regularly link their case surveillance to immunization information system data are included in these incidence rate estimates: Alabama, Arizona, Arkansas, Colorado, Connecticut, Florida, Georgia, Idaho, Indiana, Kansas, Louisiana, Maryland, Massachusetts, Michigan, Nebraska, New Mexico, New York, New York City (New York), North Carolina, Philadelphia (Pennsylvania), Rhode Island, Tennessee, Utah, and Wisconsin; 20 jurisdictions also report deaths among vaccinated and unvaccinated people. These jurisdictions represent 36% of the total U.S. population and all ten of the Health and Human Services Regions. This list will be updated as more jurisdictions participate.
Incidence rate estimates: Weekly age-specific incidence rates by vaccination status were calculated as the number of cases or deaths divided by the number of people either fully vaccinated (cumulative) or unvaccinated (obtained by subtracting the cumulative number of fully vaccinated and current estimates of partially vaccinated people from the 2019 U.S. intercensal population estimates) and multiplied by 100,000. Overall incidence rates were age-standardized using the 2000 U.S. Census standard population. Rates are not adjusted for time since vaccination, underlying conditions, or other demographic factors besides age . All rates are plotted by positive specimen collection date to reflect when incident infections occurred.
Incidence rate ratios (IRRs): IRRs for the past one month were calculated by dividing the average weekly incidence rates among unvaccinated people by that among fully vaccinated people.
