COVID-19 Vaccine Doses: Selected Data
Sources on Allocation, Distribution, and
Administration
Updated February 10, 2021
The selected 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 is not intended to
be a comprehensive source list. 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). 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?”
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.
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 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. The vaccines currently approved (Pfizer-BioNTech and Moderna) require two
doses for full effectiveness. Federal health care programs (e.g., Indian Health Service) manage and report
vaccine data through a similar process.
CDC Sources
CDC’s COVID Data Tracker tracks total doses distributed, total doses administered, the number of people
who have received at least one dose, and the number of people who have received two doses. The map
shows counts and per capita distribution and administered (per 100,000 population). 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). National data are also provided on the number of doses
administered by vaccine type (Moderna or Pfizer). Vaccinations in Long Term Care Facilities shows the
number of doses administered via the Federal Pharmacy Partnership for Long-Term Care Program.
State vaccine distribution allocation spreadsheets are available from CDC (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
acquired from state and other jurisdiction-specific sources.
Bloomberg provides international, national, and state data from “government websites, official statements
and Bloomberg interviews,” and notes that “[l]ocal governments and the CDC sometimes report different
totals for the same jurisdiction; in these cases Bloomberg uses the higher number. It can take several days
for counts to be reported to databases.”
Covid Act Now has state, county, and metro area data on the percentage of people who have received
their first vaccine dose. Data are not yet available for all counties or metro areas. Data are from CDC,
supplemented by metro and county dashboards when available.
Johns Hopkins University & Medicine provides state-level data from Centers for Civic Impact, which has
compiled links to state vaccination data dashboards; some state dashboards may also track local data.
They also track international vaccine data.
Kaiser Family Foundation publishes state-level vaccination data by race and ethnicity, compiled from
state agency websites. Not all states report these data.
New York Times provides additional 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.

they are researching.
