Did Edward Jenner get smallpox?

In 1757, an 8-year-old boy was inoculated with smallpox in Gloucester (4); he was one of thousands of children inoculated that year in England. The procedure was effective, as the boy developed a mild case of smallpox and was subsequently immune to the disease. His name was Edward Jenner.

Who started the smallpox?

Smallpox is thought to have originated in India or Egypt at least 3,000 years ago. The earliest evidence for the disease comes from the Egyptian Pharaoh Ramses V, who died in 1157 B.C. His mummified remains show telltale pockmarks on his skin.

When was the last case of smallpox?

Widespread immunization and surveillance were conducted around the world for several years. The last known natural case was in Somalia in 1977. In 1980 WHO declared smallpox eradicated – the only infectious disease to achieve this distinction.

Can smallpox come back?

Smallpox was eradicated (eliminated from the world) in 1980. Since then, there haven’t been any recorded cases of smallpox. Because smallpox no longer occurs naturally, scientists are only concerned that it could reemerge through bioterrorism.

What does a smallpox scar look like?

A smallpox vaccine scar is a distinctive mark that smallpox vaccination leaves behind. The scar may be round or oblong, and it may appear deeper than the surrounding skin. Usually, the scar is smaller than the diameter of a pencil eraser, though it can be larger.

Why is the smallpox virus kept?

Due to resistance from the U.S. and Russia, in 2002 the World Health Assembly agreed to permit temporary retention of the virus stocks for specific research purposes. Destroying existing stocks would reduce the risk involved with ongoing smallpox research; the stocks are not needed to respond to a smallpox outbreak.

Why has smallpox not been destroyed?

Smallpox kills about a third of the people it infects. It’s serious business. But there are also lots of reasons to hold off on destroying the virus: the most commonly cited is that smallpox is needed to finish research and development on vaccines and drugs that could fight a future outbreak.
