# DoW Adds $22.3 Million BioThrax Order

On November 4, 2026, Emergent BioSolutions received an option-period delivery order modification worth up to $22.3 million under its existing IDIQ contract to supply BioThrax anthrax vaccine to the U.S. Department of War for military pre-exposure prophylaxis. The first delivery, valued at approximately $7.4 million, is expected in 2026, with remaining deliveries in 2027. This is an incumbent-contract action, not a new open solicitation; a separate August 2026 contract modification for approximately $24 million covered CYFENDUS anthrax vaccine for BARDA preparedness requirements.

- The BioThrax order is identified under contract W911SR24D0001. Its option-period structure and delivery schedule provide relevant demand signals for suppliers supporting military anthrax countermeasures.
- Because this action modifies an existing IDIQ rather than opening competition, potential entrants should not treat it as an immediate bid opportunity. The source identifies future anthrax-countermeasure requirements and related supply-chain opportunities as areas to watch.
- Emergent is supplying both BioThrax to DoW and CYFENDUS to BARDA, indicating procurement activity across military prophylaxis and broader anthrax preparedness.
