## Other entities in NIH
### ARPA-H

The Advanced Research Projects Agency for Health (ARPA-H) is an entity formerly within the Office of the United States Secretary of Health and Human Services, which was created by Congress in the Consolidated Appropriations Act, 2022. Modeled after DARPA, HSARPA, IARPA, and ARPA-E, it is intended to pursue unconventional research projects through methods not typically used by federal agencies or private sector companies. Secretary Xavier Becerra delegated ARPA-H to the NIH on May 24, 2022. It received $1 billion in appropriations in 2022, and $1.5 billion in 2023, and as of June 2023 it is requesting $2.5 billion for 2024.
