COVID-19 Vaccination: Selected U.S. Data
Sources
Updated April 15, 2021
The sources below can help congressional staff track the progress of the U.S. 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 Mellon University, AP-NORC,
University of Minnesota, 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 allocation 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 (as of this writing, the use of this vaccine is
paused).
CDC Sources
CDC’s COVID Data Tracker tracks delivery and administration of doses as well as numbers and
percentages of people vaccinated. Doses per capita and percentage vaccinated are provided for the total
population and populations aged 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 state vaccine allocation spreadsheets.
Non-CDC Sources
Non-CDC sources provide different visualizations and analyses of CDC vaccine data and incorporate data
from state and other jurisdiction-specific sources.
Bloomberg provides visualizations of CDC data, “people covered” by administered doses, demographic
data from state and local agencies, and international data. Some links require a free account.
Covid Act Now tracks the percentage of people vaccinated. State-level data are from CDC, supplemented
by metro and county dashboards where available.
Johns Hopkins University & Medicine (JHU) provides state-level data from CDC and Centers for Civic
Impact. JHU also tracks international data.
Kaiser Family Foundation publishes race and ethnicity data, compiled from state agency websites.
New York Times (NYT) provides visualizations of CDC data.
Washington Post provides data from CDC and states, and estimates the share of eligible people who have
been vaccinated.
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. “People covered” is a figure calculated by Bloomberg to facilitate international comparisons.
b. “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)
c. People “ful y vaccinated” are those who have received the second dose of a two-dose vaccine or one dose of a single-
shot vaccine. (CDC)
d. Not all states report demographics.
