Human-Animal Chimera Prohibition Act of 2025

# Human-Animal Chimera Prohibition Act of 2025 - Summary **What the Bill Would Do:** This bill would prohibit the creation of human-animal chimeras—organisms that contain both human and animal cells or genetic material mixed together. If passed, it would ban federally funded research involving the creation of chimeras and would criminalize private efforts to create them as well. The legislation aims to prevent scientific experimentation that combines human and animal biological material. **Who It Affects and Key Provisions:** The bill would impact research institutions, universities, and private laboratories that conduct biomedical research.

It would restrict funding from federal agencies (like the National Institutes of Health) for chimera research and establish penalties for violations. The bill affects scientists working on regenerative medicine, organ transplantation research, and other biological studies that might involve human-animal cell combinations. **Current Status:** HR 2161 was introduced in the 119th Congress by Representative Christopher Smith (R-NJ) and is currently in committee, meaning it has not yet been debated or voted on by the full House. The bill remains in the early stages of the legislative process.
