Researcher's Death at Siberian Lab Raises Questions

A laboratory researcher died in September after an incident at Russia's State Research Center of Virology and Biotechnology, known as Vector. The facility, located in Koltsovo, Siberia, houses samples of dangerous pathogens, including smallpox.

Vector confirmed the death on November 25, identifying the individual as a laboratory worker. The center stated the worker died following an accident but did not provide further details. Local media reported an explosion occurred in a biosafety level 4 laboratory, causing a fire and leaving a worker with severe burns.

The institute informed the World Health Organization (WHO) about the incident. Vector stated the accident did not involve biological materials and posed no biological threat. The WHO confirmed it received information about the incident. A spokesperson for the WHO stated the incident did not involve the pathogen smallpox.

Vector scientists previously published research on modifying smallpox to potentially target cancer cells. The institute maintains some of the world's few remaining official smallpox stocks. The WHO oversees the destruction or continued secure storage of these samples. Scientists at Vector also conduct research on other pathogens such as Ebola, anthrax, and highly pathogenic avian influenza.
