How can I prevent smallpox?

ANSWER

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.
