I came across an interesting story. Smallpox was one of the disease scourges of history. It is now conquered from the world and probably found in Level IV deadly pathogen labs. We began to conquer the disease when Edward Jenner developed an inoculation technique by using milder cowpox to infect people to develop immunity. Queen Elizabeth I is believed to have had smallpox in her earlier girlhood years. Just think of how history would have changed if she had succumbed.

Back to the story where scientists have determined the smallpox strains used to vaccinate Civil War soldiers. The story is here.
