SIGA’s full 19C BARDA Contract has up to $414 million of procurement-related options remaining for future exercise.

The exercise emphasizes the critical value of our smallpox anti-viral treatment in that effort, and underscores SIGA’s commitment to working with BARDA and the Office of the Assistant Secretary for Preparedness and Response (ASPR) to protect against the threat of a potential smallpox outbreak or bioterror attack.”

About Smallpox1

Smallpox is a contagious, disfiguring and often deadly disease that has affected humans for thousands of years. Naturally-occurring smallpox was eradicated worldwide by 1980, the result of an unprecedented global immunization campaign. Samples of smallpox virus have been kept for research purposes. This has led to concerns that smallpox could someday be used as a biological warfare agent. A vaccine can prevent smallpox, but the risk of the current vaccine's side effects is too high to justify routine vaccination for people at low risk of exposure to the smallpox virus.
