COVID-19 Vaccination: Selected U.S. Data
Sources
Updated March 16, 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 vaccine questions, including “How Do I Get a Vaccine?” Vaccine eligibility varies by
state, locality, and provider. Sources tracking state eligibility policies include Kaiser Family Foundation,
New York Times, USAFacts, National Governors Association, Johns Hopkins University, and National
Academy for State Health Policy.
Example data sources on public attitudes toward vaccination include Census Bureau (tables), 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 other jurisdiction sites. Doses are then administered to patients by providers that also report
administration data to jurisdictions and CDC. 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 tracks the delivery and administration of doses and the number and
percentage of people vaccinated. Doses per capita and percentage vaccinated are provided for the total
population and the population aged 18 and older. Data are available nationally, by state, and by federal
entity (i.e., Bureau of Prisons, Department of Defense, Indian Health Service, and Veterans Health
Administration). CDC also provides national counts of doses delivered and administered and people fully
vaccinated, by vaccine type (i.e., J&J/Janssen, Moderna, Pfizer-BioNTech). Vaccinations in Long Term
Care Facilities tracks data from the Federal Pharmacy Partnership for Long-Term Care Program.
CDC also has state vaccine allocation spreadsheets (within a dataset, click “View Data” and export
spreadsheet).
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, demographic data from state and local agencies, and
international data. Some links require a free account.
Covid Act Now tracks the percentage of people who have received their first vaccine dose by state and
selected counties and metro areas. Data are from CDC, supplemented by metro and county dashboards
when 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 data by race and ethnicity, compiled from state agency websites. Not
all states report these data.
New York Times (NYT) provides visualizations of CDC data.
Washington Post provides data from CDC and states, as well as priority population estimates by partners.
It also has the percentage of the priority populations that have been vaccinated.
Links to state data dashboards have been compiled by CDC (click map). Some state dashboards also track
local data.
