COVID-19 Vaccination: Selected U.S. Data 
Sources 
Updated June 23, 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, 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.  
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, 
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 to the appropriate state and jurisdictional 
sites. States then allocate and distribute doses to health departments, health care systems, and multi-
county entities, which can further re-allocate to local physician offices and other 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 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 provides data on doses and people vaccinated, for the total population and 
populations aged 12+, 18+, and 65+. Some data are available by federal entity (i.e., Bureau of Prisons, 
Department of Defense, Indian Health Service, and Veterans Health Administration). CDC also has data 
on international vaccination efforts. 
Non-CDC Sources 
Non-CDC sources provide different visualizations and analyses of CDC data and incorporate data from 
various jurisdiction-specific sources:  
  American Public Media Research Lab (APM) 
  Bloomberg (some links require a free account, also international data)  
  Covid Act Now (and Harvard analysis with congressional district estimates) 
  Johns Hopkins University & Medicine (JHU) (also international data) 
  Kaiser Family Foundation (KFF) 
  New York Times (NYT) 
  Washington Post (WP) 
Centers for Medicare & Medicaid Services (CMS) posts nursing home-reported data on staff and resident 
vaccination status. 
CDC (click map) compiles links to state dashboards, which may also track local data.

Source: CRS based on data sources as of June 21, 2021. 
Note: Some sources report similar data, but with different visualizations and analysis. 
a.  Tables have federal allocations to jurisdictions. Tables do not reflect other channels such as the retail pharmacy 
program or health centers program. 
b.  “People covered” is a figure calculated by Bloomberg to facilitate international comparisons.  
c.   “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) 
d.  “Fully vaccinated” people have received the second dose of a two-dose vaccine or one dose of a single-shot vaccine. 
(CDC) 
e.  Not all states report demographics.
