New England is on alert following one death and a handful of infections of eastern equine encephalitis (EEE) virus. Vaccine research for eastern equine encephalitis has been stymied by the fact that outbreaks of the virus are sporadic, making it tough to test any jab or even predict who would most benefit from vaccination.But labs are exploring treatments that could lure the virus away from human brain cells, preventing the development of encephalitis. Why are so many viruses in the modern world ?
