GAITHERSBURG, Md., June 29, 2026 (GLOBE NEWSWIRE) -- Emergent BioSolutions (NYSE:EBS) today announced it has been awarded a contract modification valued at $52.7 million from the Administration for Strategic Preparedness and Response (ASPR) at the United States Department of Health and Human Services to supply ACAM2000^®(Smallpox and Mpox (Vaccinia) Vaccine, Live) vaccine, ancillaries as well as diluent replacement lots for smallpox preparedness and response needs. Deliveries are expected to begin this month.

“This new contract modification for ACAM2000^® underscores the U.S. government’s continued focus on biodefense preparedness and reflects Emergent’s longstanding role to collaborate and help protect civilians and warfighters against potential smallpox and mpox threats,” said Paul Williams, senior vice president, head of products business, global government & public affairs at Emergent. “In this increasingly dangerous world, we are proud to continue supporting the U.S. government as they continue to take critical, proactive steps on biodefense preparedness.”

This award follows Emergent’s recent announcements that the Saudi Food and Drug Authority has approved ACAM2000® for immunization against smallpox and mpox in high-risk individuals and that Singapore’s Health Sciences Authority has approved an expanded indication for ACAM2000^® to include prevention of mpox disease in adults determined to be at high risk for mpox infection.

Experts consider smallpox to be a credible bioterror threat, with potential health, economic and national security implications due to its mortality rate.¹Emergent specializes in developing, manufacturing and delivering medical countermeasures to the U.S. government and allies around the world to support health preparedness and help protect the public from potential threats like smallpox, mpox, Ebola, anthrax and botulism.

This contract modification is under Emergent’s existing 10-year contract (75A50119C00071) with ASPR.
