COVID-19 Vaccine Doses: Selected Data Sources on Allocation, Distribution, and Administration

"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-19Vaccine 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..."
