Please see below.\n\nChicago residents who are up to date with COVID-19 vaccines by ZIP Code, based on the reported home address and age group of the person vaccinated, as provided by the medical provider in the Illinois Comprehensive Automated Immunization Registry Exchange (I-CARE). \n\n\u201cUp to date\u201d refers to individuals who meet the CDC\u2019s updated COVID-19 vaccination criteria based on their age and prior vaccination history. For surveillance purposes, up to date is defined based on the following criteria: \n\nPeople ages 5 years and older: \n\u00b7 Are up to date when they receive 1+ doses of a COVID-19 vaccine during the current season.\n\nChildren ages 6 months to 4 years: \n\u00b7 Children who have received at least two prior COVID-19 vaccine doses are up to date when they receive one additional dose of COVID-19 vaccine during the current season, regardless of vaccine product.\n\u00b7 Children who have received only one prior COVID-19 vaccine dose are up to date when they receive one additional dose of the current season's Moderna COVID-19 vaccine or two additional doses of the current season's Pfizer-BioNTech COVID-19 vaccine.\n\u00b7 Children who have never received a COVID-19 vaccination are up to date when they receive either two doses of the current season's Moderna vaccine or three doses of the current season's Pfizer-BioNTech vaccine.\n\nThis dataset takes the place of a previous dataset, which covers doses administered from December 15, 2020 through September 13, 2023 and is marked as historical:\n- https://data.cityofchicago.org/Health-Human-Services/COVID-19-Vaccinations-by-ZIP-Code/553k-3xzc.\n\nData Notes: \n\nWeekly cumulative totals of people up to date are shown for each combination ZIP Code and  age group. Note there are rows where age group is \"All ages\" so care should be taken when summing rows.\n\nCoverage percentages are calculated based on the cumulative number of people in each ZIP Code and age group who are considered up to date as of the week ending date divided by the estimated number of people in that subgroup. Population counts are obtained from the 2020 U.S. Decennial Census.  For ZIP Codes mostly outside Chicago, coverage percentages are not calculated reliable Chicago-only population counts are not available. Actual counts may exceed population estimates and lead to coverage estimates that are greater than 100%, especially in smaller ZIP Codes with smaller populations. Additionally, the medical provider may report a work address or incorrect home address for the person receiving the vaccination, which may lead to over- or underestimation of vaccination coverage by geography. All coverage percentages are capped at 99%. \n\nWeekly cumulative counts and coverage percentages are reported from the week ending Saturday, September 16, 2023 onward through the Saturday prior to the dataset being updated.\n\nAll data are provisional and subject to change. Information is updated as additional details are received and it is, in fact, very common for recent dates to be incomplete and to be updated as time goes on. At any given time, this dataset reflects data currently known to CDPH. \n\nNumbers in this dataset may differ from other public sources due to when data are reported and how City of Chicago boundaries are defined.  \n \nThe Chicago Department of Public Health uses the most complete data available to estimate COVID-19 vaccination coverage among Chicagoans, but there are several limitations that impact our estimates. Individuals may receive vaccinations that are not recorded in the Illinois immunization registry, I-CARE, such as those administered in another state, causing underestimation of the number individuals who are up to date. Inconsistencies in records of separate doses administered to the same person, such as slight variations in dates of birth, can result in duplicate records for a person and underestimate the number of people who are up to date.\n\nFor all datasets related to COVID-19, please", "distribution": [{"@type": "dcat:Distribution", "describedBy": "https://data.cityofchicago.org/api/views/2ani-ic5x/columns.json", "describedByType": "application/json", "downloadURL": "https://data.cityofchicago.org/api/views/2ani-ic5x/rows.json?accessType=DOWNLOAD", "mediaType": "application/json"}, {"@type": "dcat:Distribution", "describedBy": "https://data.cityofchicago.org/api/views/2ani-ic5x/columns.rdf", "describedByType": "application/rdf+xml", "downloadURL": "https://data.cityofchicago.org/api/views/2ani-ic5x/rows.rdf?accessType=DOWNLOAD", "mediaType": "application/rdf+xml"}, {"@type": "dcat:Distribution", "describedBy": "https://data.cityofchicago.org/api/views/2ani-ic5x/columns.xml", "describedByType": "application/xml", "downloadURL": "https://data.cityofchicago.org/api/views/2ani-ic5x/rows.xml?accessType=DOWNLOAD", "mediaType": "application/xml"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.cityofchicago.org/api/views/2ani-ic5x/rows.csv?accessType=DOWNLOAD", "mediaType": "text/csv"}], "identifier": "https://data.cityofchicago.org/api/views/2ani-ic5x", "issued": "2026-02-11", "keyword": ["age", "covid-19", "immunization", "public health", "zip code"], "landingPage": "https://data.cityofchicago.org/d/2ani-ic5x", "modified": "2026-05-14", "publisher": {"@type": "org:Organization", "name": "data.cityofchicago.org"}, "theme": ["Health & Human Services"], "title": "COVID-19 Vaccination Coverage, ZIP Code"}
