NEW YORK, Aug. 31, 2020 (GLOBE NEWSWIRE) -- SIGA Technologies, Inc. (SIGA) (NASDAQ: SIGA), a commercial-stage pharmaceutical company focused on the health security market, today announced that Dr. Dennis Hruby, SIGAs Chief Scientific Officer, has been named a recipient of the 2021 American Society for Microbiology (ASM) Award for Applied and Biotechnological Research. The award recognizes an outstanding scientist with distinguished research achievements in the development of products, processes and technologies that have advanced the microbial sciences.

"It is an honor to receive this prestigious award, especially given the high quality of microbial research being conducted in academic and corporate laboratories around the world, said Dr. Hruby. The current COVID-19 pandemic underscores the importance of continued research into microbial diseases and the urgent need to be prepared to respond effectively both to novel infectious agents and historic scourges such as smallpox. ASM and its members have a critical role to play in achieving this goal and I am proud that my work on the development of TPOXX has warranted their recognition.

On behalf of everyone at SIGA, I would like to congratulate Dennis on receiving this award and well-deserved recognition, said Dr. Phil Gomez, CEO of SIGA. Dennis research has been instrumental in advancing not only SIGAs product development and regulatory activities, but also the field of microbial sciences as a whole. SIGA is committed to working with experts like Dennis and our collaborators in the U.S. government and the biopharmaceutical industry to expand the opportunities for TPOXX and advance global biopreparedness.

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.
