Responding to current concerns about the possibility that terrorist organizations might deliberately infect populations with smallpox, World Health Organization (WHO) Director-General Gro Harlem Brundtland, MD, MPH, asked the agency's Smallpox Advisory Group to review guidelines on smallpox vaccination.
Current guidelines recommend vaccinating only individuals who are at risk of exposure, such as laboratory workers conducting smallpox research. Brundtland asked the group to consider whether the WHO should change these recommendations to take into account the potential malicious use of smallpox virus.
