Schaffner: NIH clinical trial of Zika vaccine could prevent future outbreaks globally
As health officials work to contain the country's first Zika outbreak, centered in a Miami neighborhood, scientists at the National Institutes of Health announced the launch Wednesday of a clinical trial of an experimental Zika vaccine. Even if the Zika vaccine isn't ready in time to prevent many infections in Brazil, the country hardest hit by the virus, it could help prevent cases elsewhere in the world, said William Schaffner, a professor at the Vanderbilt University School of Medicine.
