There are now only two locations where variola virus is officially stored and handled under WHO supervision: By the time the Intensified Eradication Program began insmallpox had already been eliminated in North America and Europeleaving South America, Asia, and Africa smallpox was never widespread in Australia.

Crucially all of at least four who Jenner deliberately inoculated with smallpox virus resisted it. The current formulation of smallpox vaccine is a live virus preparation of infectious vaccinia virus.

Both enveloped and unenveloped virions are infectious. On October 22, he developed a fever. Studies of smallpox cases in Europe in the s and s demonstrated that the fatality rate among persons vaccinated less than 10 years before exposure was 1.

Doctors repeat this process several times. However, it is theorized that other countries may have possession of the virus as well. As the campaign neared its goal, Fenner and his team played an important role in verifying eradication.

Civil war, famine, and refugees made the task even more difficult. The patient would then develop a mild case [of smallpox], recover, and thereafter be immune. The smallpox vaccine caused one to two deaths for every million people vaccinated.

Prevention: The Smallpox Vaccine. Scientists use the cousin virus to variola -- the vaccinia virus – to make the smallpox vaccine, because it poses fewer health risks.

The vaccine prompts the body's immune system to make the tools, called antibodies, it needs to protect against the variola virus and help prevent smallpox disease.

One of the first methods for controlling the spread of smallpox was the use of variolation. Named after the virus that causes smallpox (variola virus), variolation is the process by which material from smallpox sores (pustules) was given to people who had never had smallpox.
