BREAKING: New proposed OMB regulation, applying to all federal grants, requiring grant reviews by senior political appointees and re-emphasizes that "peer review remains advisory and does not replace agency discretion". #standupforscience public-inspection.federalregister.gov/2026-10817.pdf

Our NIH-funded research - including as part of CREID - developed, deployed, and established capacity for many of the core tools and countermeasures used during outbreaks. Diagnostics, sequencing, monoclonals and vaccines. As we're facing a new foe with none of those, all that work, defunded. Gone.
