“We are very pleased that the UK has taken this important step in health emergency preparedness, not just for the immediate need for the current monkeypox outbreak, but for wider preparedness by approving tecovirimat for the treatment of ‘a wide range of uses,’ said Dr. Phil Gomez, CEO of SIGA. “As we have learned in the ongoing COVID-19 pandemic, building strong stocks in response to infectious disease outbreaks is of vital importance around the world.

In early 2022, SIGA also received marketing authorization for tecovirimat from the European Medicines Agency for the treatment of smallpox, monkeypox, cowpox and complications of vaccinia infection.

Smallpox is a contagious, disfiguring and often fatal disease that has affected humans for thousands of years. Natural smallpox was eradicated worldwide in 1980, thanks to an unprecedented global vaccination campaign. Smallpox virus samples were retained for research purposes. This led to fears that smallpox could one day be used as a biological warfare agent. A vaccine can prevent smallpox, but the risk of side effects from the current vaccine is too high to justify routine vaccination of people at low risk of exposure to the smallpox virus.
