Crans urges that vaccinations be provided to horses by only licensed veterinarians to ensure that their protection is effective. Infected horses are often found to have been "improperly vaccinated or (were) vaccinated with vaccine that had lost its protective properties."
The vaccinations when properly given are only effective for one year. Annual booster shots are required. Animals receiving their first vaccination will require a two-shot series to guarantee that their protection is adequate.
Humans that are infected with EEEV may not have any apparent illness or symptoms. Cases that are classified as severe "begin with the sudden onset of headache, high fever, chills, and vomiting. The illness may then progress into disorientation, seizures, or coma." These severe cases involve an inflammatory condition of the brain called encephalitis advises the CDC.
