Disease X Act of 2023

This bill amends the Public Health Service Act to expand federal efforts in preparing for pandemic threats. It specifically requires agencies like the CDC and NIH to prioritize research into flexible medical countermeasures (including vaccines and treatments) for respiratory viruses with pandemic potential, and to develop platform manufacturing technologies for faster production. The key change directs funding and focus toward "pathogen-agnostic" approaches that work against multiple virus families, rather than targeting single viruses. This primarily affects federal public health agencies and their research programs, aiming to improve readiness for future outbreaks.
