the 1855 and before. The largest outbreak of yellow fever in the
US killed more than 5000 people in Philadelphia. It destroyed

learned to become immune to the disease. Procedures that allow a person
to become immune to the disease have not yet been perfected. They still
have a slight chance of failure resulting in death. Biological Warfare

any because it is such a deadly disease. Though there is still a chance
that people might use the disease for warfare in later years.
