COVID-19 Vaccination: Selected U.S. Data
Sources
Updated August 25, 2021
The sources below can help congressional staff track the progress of the U.S. Coronavirus Disease 2019
(COVID-19) vaccination campaign at the national, state, and local levels.
Sources were selected for having commonly cited and frequently requested data. This list is not intended
to be comprehensive. Because different resources use different methodologies, readers should check
websites’ notes and caveats, and use caution when comparing data. For assistance in interpreting or
analyzing these data, congressional staff should contact CRS (202) 707-5700, or place a request at CRS’s
website).
For an overview of data systems and considerations for Congress, see CRS Insight IN11584, Tracking
COVID-19 Vaccines: U.S. Data Systems and Related Issues.
Centers for Disease Control and Prevention’s (CDC’s) Vaccines for COVID-19 website can assist
constituents with questions about the vaccine and how to get vaccinated.
Example data sources on public attitudes toward vaccination include CDC’s National Immunization
Survey and State of Vaccine Confidence Insights Report, Census Bureau (HHS analysis), Kaiser Family
Foundation, Carnegie Mellon University, University of Washington, and scholarly articles.
About Vaccine Data
In the COVID-19 vaccine program, doses are first allocated and made available to states and other
jurisdictions for ordering. Once ordered, doses are delivered (i.e., distributed) to appropriate state and
jurisdictional sites. States then allocate and deliver doses to health departments, health care systems,
pharmacies, and multi-county entities, which can further re-allocate to local clinical sites. Providers then
administer doses to patients and report administration data to jurisdictions and CDC. (See CDC’s How
COVID-19 Vaccines Get to You and About COVID-19 Vaccine Delivered and Administration Data.)
Federal health care programs (e.g., Veterans Health Administration) manage vaccine data through a
similar process.
Comirnaty (formerly known as the Pfizer-BioNTech COVID-19 vaccine) is approved as a two-dose
vaccine for individuals aged 16+. Comirnaty remains authorized for emergency use only for individuals

aged 12-15. Vaccines manufactured by Moderna (a two-dose vaccine) and J&J/Janssen (a single-dose
vaccine) are currently authorized for emergency use for individuals aged 18+. An additional dose of the
Moderna and Comirnaty/Pfizer-BioNTech vaccines is authorized for certain immunocompromised
individuals.
CDC Sources
CDC provides data on doses and people vaccinated, for the total population and populations aged 12+,
18+, and 65+. Some aggregated national data are available for federal entities (Bureau of Prisons,
Department of Defense, Indian Health Service, and Veterans Health Administration; see “Data Table”).
CDC also tracks hospitalized or fatal vaccine breakthrough infections. CDC continues to study vaccine
effectiveness in real-world conditions.
CDC (click map) compiles links to state dashboards, which may also track local data.
Non-CDC Sources
Non-CDC sources provide different visualizations and analyses of CDC data and incorporate data from
various jurisdiction-specific sources:
Bloomberg
Covid Act Now (and Harvard analysis with congressional district estimates)
Johns Hopkins University & Medicine (JHU)
Kaiser Family Foundation (KFF)
New York Times (NYT) (subscription required)
Washington Post (WP)
Centers for Medicare & Medicaid Services (CMS) posts nursing home-reported data.
