You have been given a large grant to do postgraduate research on live smallpox viruses. Where in the world would you find samples?

Guida verificata passo dopo passo
1
Understand that smallpox virus (Variola virus) was declared eradicated worldwide by the World Health Organization (WHO) in 1980 after a successful global vaccination campaign.
Recognize that due to its eradication and potential use as a bioterrorism agent, live smallpox virus samples are not available for general research and are strictly controlled.
Identify that the only officially recognized repositories for live smallpox virus samples are two high-security laboratories: one in the United States (Centers for Disease Control and Prevention, CDC, in Atlanta) and one in Russia (State Research Center of Virology and Biotechnology, VECTOR Institute).
Note that access to these samples is highly restricted and regulated by international agreements and national laws, requiring special permissions and security clearances.
Conclude that if you were to conduct legitimate postgraduate research involving live smallpox virus, you would need to collaborate with or gain access through one of these two authorized facilities under strict biosafety and biosecurity protocols.
