tekovirimat (TPOXX) SIGA’s flagship product was approved in January 2022 by the European Medicines Agency (EMA) for the treatment of complications of smallpox, monkeypox, smallpox, and variola vaccine following smallpox vaccination. SIGA has also introduced TPOXX as a compassionate-use treatment for monkeypox in the UK, and in the US, where TPOXX is approved for use against smallpox, the CDC has used TPOXX to treat at least one monkeypox patient during the current outbreak. The FDA has not approved TPOXX for monkeypox in the United States.

About Smallbox1

Smallpox has been a contagious, disfiguring, and often fatal disease that has plagued humans for thousands of years. Naturally occurring smallpox was eradicated worldwide by 1980, as a result of an unprecedented global immunization campaign. Samples of the smallpox virus were kept for research purposes. This has led to concerns that smallpox could one day be used as a biological warfare agent. The 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.


Monkeypox is a rare disease caused by the monkeypox virus. Monkeypox virus belongs to the genus Corticoviruses in the family Poxviridae. The orthopoxvirus genus also includes poxvirus (which causes smallpox), vaccinia virus (used in the smallpox vaccine), and cowpox virus.
