Operational framework for the deployment of the WHO smallpox vaccine emergency stockpile in response to a smallpox event

Overview

In 1980, when smallpox eradication was achieved, it was recognized that there was a need for WHO to maintain an emergency reserve of Smallpox Vaccine Emergency Stockpile (SVES). WHO was given a set of formal responsibilities for maintaining capacity and expertise to respond to a re-emergence of smallpox in the post-eradication era as both a preparedness strategy and a possible deterrent to intentional release.
