From the Document: "To date, the U.S. Food and Drug Administration (FDA) has authorized for emergency use [hyperlink] three Coronavirus Disease 2019 (COVID-19) vaccines; additional vaccines [hyperlink] may become available within months. Federal efforts to develop, manufacture, regulate, purchase, and distribute vaccines have involved a number of agencies. Under the Trump Administration, such efforts were largely organized under Operation Warp Speed [hyperlink] (OWS) led by the Department of Health and Human Services (HHS) and the Department of Defense (DOD). Coordinated interagency efforts continue under the Biden Administration. Many aspects of federal domestic vaccine efforts have thus far been funded by appropriations in COVID-19 relief acts, especially funding to U.S. Public Health Service [hyperlink] (PHS) agencies and accounts. The following provides an overview of appropriations for selected domestic COVID-19 vaccine related activities. (With the exception of the mandatory funding provided by the American Rescue Plan Act of 2021 (ARPA), all funding amounts discussed below are classified as discretionary [hyperlink].) The following is meant to inform a general understanding of available funding, but may not capture every federal account that can be used for vaccine-related activities. In general, many of the HHS appropriations are available for multiple years or until expended, and some of the funding is transferrable [hyperlink] between accounts by the HHS Secretary."
