About this file
This document is a Change History Table documenting seven amendments to BARDA BAA-23-100-SOL-00004, a Broad Agency Announcement for medical countermeasures and research and development opportunities. The amendments span from November 2023 through March 2026, with the most recent amendment (Amendment 7) issued March 19, 2026.
Amendment 7 (March 19, 2026) made substantial updates across multiple areas of interest, including suspending AOI 2.1 (Anthrax Antitoxins), updating language for Filovirus Antivirals (AOI 2.4), and significantly revising diagnostics requirements across multiple sub-areas including biothreat agent diagnostics, antibiotic resistance diagnostics, influenza testing in OTC and CLIA waived environments, and metagenomic next-generation sequencing diagnostics. It also reopened Area of Interest #12 (Flexible and Strategic Therapeutics - FASTx) and updated multiple IEID Therapeutics areas. Amendment 6 (May 29, 2025) rescinded synthetic nucleic acid screening requirements, added supply chain risk assessment attachments, and suspended multiple AOIs including AOI 1.1 (Needle-Free Vaccine Technologies), AOI 4.5 (Decorporation Agents), and AOI 6.7 (Health Economic Impact Assessment). Earlier amendments progressively suspended additional AOIs including COVID-19 related areas while updating technical requirements, TRL specifications, and proposal evaluation criteria across vaccines, antivirals, antimicrobials, radiological/nuclear countermeasures, burn and blast medical countermeasures, and diagnostics development initiatives.
