As Russell said, the smallpox vaccine is prepared from the vaccinia
virus, not the smallpox virus, so it cannot cause smallpox. Here's a
quote from the CDC website:
Facts about vaccinia
* The vaccinia virus, the virus in the smallpox vaccine, is another
"pox"-type virus.
* Vaccinia is related to smallpox, but milder.
* The vaccinia virus may cause rash, fever, and head and body aches.
In certain groups of people, complications from the vaccinia virus
can be severe.
* Vaccinia is spread by touching a vaccination site before it has
healed or by touching bandages or clothing that have been
contaminated with live virus from the smallpox vaccination site.
* This way, vaccinia can spread to other parts of the body or to
other individuals. This is called inadvertent inoculation.
* In the past, spreading to other parts of the vaccine recipients'
body was the more common form of inadvertent inoculation.
* Careful care must be taken of the site of the vaccine to prevent
spreading of the vaccinia virus.
