Smallpox expert D. A. Henderson has been foremost in favor of destruction, while U.S. Army scientist Peter Jahrling has argued against it on the basis that further research is needed, since he believes that smallpox almost certainly exists outside of the repositories. [11] Other scientists have expressed similar opinions. [12]
The campaign aimed to provide the smallpox vaccine to those who would respond to an attack, establishing Smallpox Response Teams and using DryVax (containing the NYCBOH strain) to mandatorily vaccinate half a million American military personnel, followed by half a million health care worker volunteers by January 2004.
After smallpox was successfully eradicated in 1980, the International Certificate of Vaccination against Smallpox was cancelled in 1981, and the new 1983 form lacked any provision for smallpox vaccination. [10] [12] Thus, only yellow fever remained as vaccination requirement for international travel for which the ICV was used. [citation needed]

Travel agencies mistakenly provided certificates to some unvaccinated customers, and there were some instances of falsified documents.
The book is primarily an account of the Smallpox Eradication Program (1967–1980), the ongoing belief of the U.S. government that smallpox is still a potential bioterrorism agent, and the controversy over whether or not the remaining samples of smallpox virus in Atlanta and Moscow (the "demon" in the freezer) should be finally destroyed.
The Aral smallpox incident was a 30 July 1971 outbreak of the viral disease which occurred as a result of a field test at a Soviet biological weapons (BW) facility on an island in the Aral Sea. The incident sickened ten people, of whom three died, and came to widespread public notice only in 2002.
Diseases associated with this genus include smallpox, cowpox, horsepox, camelpox, and mpox. [ 1 ] [ 2 ] The most widely known member of the genus is Variola virus , which causes smallpox. It was eradicated globally by 1977, through the use of Vaccinia virus as a vaccine .
The 1972 Yugoslav smallpox outbreak was the largest outbreak of smallpox in Europe after the Second World War. [1] It was centered in Kosovo , a province of Serbia within Yugoslavia , and the capital city of Belgrade .
