COVID-19 Vaccination: Selected U.S. Data
Sources
Updated September 30, 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. For help interpreting or analyzing
these data, congressional staff should contact CRS (202-707-5700, or place an online request).
For an overview of considerations for Congress, see CRS Insight IN11584, Tracking COVID-19 Vaccines:
U.S. Data Systems and Related Issues. For international sources see CRS Insight IN11732, International
COVID-19 Data and Vaccine Distribution: Selected Resources.
Centers for Disease Control and Prevention’s (CDC’s) Vaccines for COVID-19 can assist constituents
with questions about the vaccines.
Example sources on public attitudes toward vaccination include CDC’s National Immunization Survey
and State of Vaccine Confidence Insights Report, Census Bureau, Kaiser Family Foundation, Carnegie
Mel on University, Johns Hopkins, 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 (distributed) to appropriate state and
jurisdictional sites. States then al ocate and deliver doses to health departments, health care systems,
pharmacies, and multi-county entities, which can further re-al ocate 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.
Comirnaty (the Pfizer-BioNTech COVID-19 vaccine) is approved as a two-dose vaccine for ages 16+.
Comirnaty is also authorized for uses that fal outside the scope of its approval—that is, as a two-dose

regimen in individuals aged 12-15, as a third dose for certain immunocompromised individuals aged 12+,
and as a single booster dose to be given at least six months after the primary series in certain individuals
aged 18+. For more information, see CRS Report R46913, FDA Approval of the Pfizer-BioNTech COVID-
19 Vaccine: Frequently Asked Questions.
Vaccines manufactured by Moderna (a two-dose vaccine) and J&J/Janssen (a single-dose vaccine) are
currently authorized for emergency use for ages 18+. The Moderna vaccine is also authorized to be given
as a third dose to certain immunocompromised individuals.
CDC Sources
CDC provides data on doses and people vaccinated, for the total population and ages 12+, 18+, and 65+.
Some aggregated national data are available for federal entities (Bureau of Prisons, Department of
Defense, Indian Health Service, and Veterans Health Administration; see “Data Table”). CDC also tracks
hospitalized or fatal vaccine breakthrough infections. CDC continues to study vaccine effectiveness in
real-world conditions.
CDC (click map) compiles links to state dashboards, which may also track local data.
Non-CDC Sources
Non-CDC sources provide different visualizations and analyses of CDC data and incorporate data from
various jurisdiction-specific sources:
 Bloomberg
 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.
