West Nile vaccine in the works | Health

Scientists at the University of Oklahoma are working on a West Nile virus vaccine. They have isolated strains of the virus and then use a chemical to inactivate it. In lab models this technique protects against infection.

This year's West Nile outbreak is the worst in US history. Alabama has more that a dozen confirmed cases and has reported one death. The CDC reports that all but 2 states have reported West Nile activity.
