COVID-19 Vaccination: Selected U.S. Data
Sources
Updated July 29, 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 across sources or geographies. 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) COVID-19 Vaccine website can assist constituents
with questions, including “How do I find a free vaccine?”
Example data sources on public attitudes toward vaccination include CDC, Census Bureau (HHS
analysis), Kaiser Family Foundation, Carnegie Mellon University, University of Washington, AP-NORC,
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 to appropriate state and jurisdictional sites.
States then allocate and distribute 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.
Two of the vaccines currently authorized for emergency use, Pfizer-BioNTech and Moderna, are given in
two doses. A third, J&J/Janssen, is a single-dose vaccine.

CDC Sources
CDC provides data on doses and people vaccinated, for the total population and populations aged 12+,
18+, and 65+. Some data are available by federal entity (Bureau of Prisons, Department of Defense,
Indian Health Service, and Veterans Health Administration). CDC also tracks hospitalized or fatal vaccine
breakthrough infections. CDC continues to study vaccine effectiveness in real-world conditions.
Non-CDC Sources
Non-CDC sources provide different visualizations and analyses of CDC data and incorporate data from
various jurisdiction-specific sources:
Bloomberg (may require free account)
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.
CDC (click map) compiles links to state dashboards, which may also track local data.

Source: CRS based on sources as of July 29, 2021.
Notes: Some sources report similar data, but with different visualizations and analysis.
a. Tables reflect federal allocations to jurisdictions, not other channels such as the retail pharmacy program.
b. See “View (right axis).”
c. “‘People covered’ divides the doses administered for each vaccine type by the number of doses required for full
vaccination.”(Bloomberg)
d. Click “Vaccines”: “Daily.” For “Select Metric,” one can choose “Daily total vaccines administered” or “Daily vaccines
administered by [1st or 2nd] dose.”
e. “The adjusted metric is the standard being used to assess administration ratios for the US COVID-19 Vaccination
Program. Interpretation of these metrics for remote jurisdictions (e.g., territories, Hawaii, Alaska) should be done
with caution, as they have different delivery schedules than jurisdictions located in the continental United States.”
(CDC)
f.
Search state, city, or county, then scroll to “% Vaccinated” for trend.
g. “Fully vaccinated” people have received the second dose of a two-dose vaccine or one dose of a single-shot vaccine.
(CDC)
h. Not all states report demographics.
