COVID-19 Vaccination: Selected U.S. Data
Sources
Updated August 1, 2022
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).
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,
COVIDVaxView, and State of Vaccine Confidence Insights Report, Kaiser Family Foundation, Carnegie
Mellon University, Johns Hopkins, and scholarly articles.
Vaccines.gov maps vaccination sites. Vaccine Equity Planner (Ariadne Labs) helps identify “vaccine
deserts” that lack convenient access to vaccination.
About Vaccine Data
In the COVID-19 vaccine program, jurisdictions (e.g., states, territories, tribes, and local entities), federal
agencies, and pharmacy partners determine the number and types of doses to be shipped to vaccination
sites. Doses are then distributed (i.e., delivered) to vaccination administration sites such as vaccination
clinics, doctors’ offices, and pharmacies. Providers then administer doses to patients and report
administration data to jurisdictions and CDC. (See CDC’s U.S. COVID-19 Vaccination Data.) Federal
health care providers (e.g., Veterans Health Administration) manage vaccine data through a similar
process.
FDA has approved or authorized four vaccines for the prevention of COVID-19 in different age groups,
summarized in Table 1.

Notes: See FDA’s COVID-19 Vaccines for details on timing and size of doses, which vary by population, age group, and
vaccine type.
The CDC and FDA maintain public websites that provide up-to-date information on recommended
regimens, booster eligibility, and vaccine courses for each available manufacturer.
CDC Sources
CDC provides data on doses and people vaccinated. 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 rates of COVID-19 cases, deaths, and
hospitalizations by vaccination and booster status. 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 as of
September 2021)
Johns Hopkins University & Medicine (JHU)
Kaiser Family Foundation (KFF)
Washington Post (WP)
Centers for Medicare & Medicaid Services (CMS) posts nursing home-reported data.
