“In the United States, for equine encephalitides for which vaccines are available include eastern equine encephalomyelitis (EEE), western equine encephalomyelitis (WEE), Venezuelan equine encephalomyelitis (VEE) and West Nile Virus encephalomyelitis. The availability of licensed vaccine products combined with an inability to completely eliminate risk of exposure justifies immunization against EEE and WEE as core prophylaxis for all horses residing in or traveling to North America and any other geographic areas where EEE and/or WEE is endemic.  Adult horses previously vaccinated against EEE/WEE: Annual revaccination must be completed prior to vector season in the spring. In animals of high risk or with limited immunity, more frequent vaccination or appropriately timed vaccination is recommended in order to induce protective immunity during periods of likely exposure.”

“Know there’s no cure for Eastern equine encephalitis, or EEE, but there is a vaccine for the mosquito-borne illness. It’s just not commercially available for humans.The United States military developed it in the 1980s as part of a vaccine program to protect military personnel from dangerous pathogens, says Sam Telford, an epidemiologist at Tufts University.”
