Eastern Equine Encephalitis — United States
EEE/WEE vaccines currently available are formalin inactivated adjuvanted whole virus products. Early testing of bivalent (EEE/WEE) vaccines was performed by intracranial challenge with either EEE and WEE; the formalin inactivated preparations were shown to be highly efficacious protecting against clinical disease. Currently, the only available VEE vaccines are killed products; an MLV would be conditionally released in the face of an outbreak.
