COVID-19 Vaccination: Selected U.S. Data
Sources
Updated May 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. Additional sources may be added in future updates. Because different resources use
different methodologies, readers should check websites’ notes, definitions, and caveats. Readers should
also 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 the
CRS website).
For an overview of vaccine data systems and considerations for Congress, see CRS Insight IN11584,
Tracking COVID-19 Vaccines: U.S. Data Systems and Related Issues.
The Centers for Disease Control and Prevention’s (CDC’s) COVID-19 Vaccine website can assist
constituents with questions, including “How Do I Find a Vaccine?”
Example data sources on public attitudes toward vaccination include Census Bureau (HHS analysis),
University of Southern California, Kaiser Family Foundation, Carnegie Mel on University, AP-NORC,
Pew, 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, vaccines are delivered (i.e., distributed) to the appropriate state
and jurisdictional sites. States then follow a subsequent al ocation and distribution pattern to health
departments, health care systems, and multi-county entities within their jurisdictions. Doses are then
administered to patients by these providers that report administration data to jurisdictions and CDC. (See
CDC’s How COVID-19 Vaccines Get to You.) Federal health care programs (e.g., Indian Health Service)
manage and report vaccine data through a similar process.
Two of the vaccines currently approved, Pfizer-BioNTech and Moderna, require two doses for full
effectiveness. A third, J&J/Janssen, is a single-dose vaccine.

CDC Sources
CDC’s COVID Data Tracker provides data on doses and people vaccinated. Doses per capita and
percentage vaccinated are provided for the total population and for populations aged 12+, 18+, and 65+ at
the national and state levels. Some data are available by county and by federal entity (i.e., Bureau of
Prisons, Department of Defense, Indian Health Service, and Veterans Health Administration). CDC also
has data on international vaccination efforts.
Non-CDC Sources
Non-CDC sources provide different visualizations and analyses of CDC vaccination data and incorporate
data from state and other jurisdiction-specific sources:
 Bloomberg (some links require a free account, also international data)
 Covid Act Now
 Johns Hopkins University & Medicine (JHU) (also international data)
 Kaiser Family Foundation
 New York Times (NYT)
 Washington Post
Race and ethnicity data from state agency websites are compiled by American Public Media Research
Lab (APM), Kaiser Family Foundation, and Bloomberg.
Links to state data dashboards have been compiled by CDC (click map). Some state dashboards also track
local data.

Note: Some sources report similar data, but with different visualizations and analysis.
a. Tables have federal al ocations to jurisdictions. Tables do not reflect other channels such as the retail pharmacy
program or health centers program.
b. “People covered” is a figure calculated by Bloomberg to facilitate international comparisons.
c. “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, Hawai , Alaska) should be done
with caution, as they have different delivery schedules than jurisdictions located in the continental United States.”
(CDC)
d. “Ful y vaccinated” people have received the second dose of a two-dose vaccine or one dose of a single-shot vaccine.
(CDC)
e. Not al states report demographics.
f.
The Pharmacy Partnership for LTC Program ended April 23, 2021. According to Centers for Medicare & Medicaid
Services (CMS), vaccination data reported by LTC facilities wil be posted in the future at COVID-19 Nursing Home
Data (data are not yet posted as of this writing).
