Multiple vaccines are available (Duvaxyn EHV1,4, EquiGuard, EquiVac EHV-1/4, etc.), most in an inactivated virus form. [4] The Equine Herpesvirus occupies the horse in such a way that allows post infection viral persistency over the lifetime of an animal. These carrier horses may comprise up to half of a given horse population.
There is a vaccine available (ATCvet code QI05AA11 ), however its efficacy is questionable. [citation needed] The virus varies in severity from sub-clinical to very severe. [4] Most horses have been infected with EHV-1, but the virus can become latent and persist without ever causing signs of infection. [5]
There is an inactivated vaccine containing the C-84 strain for VEE virus that is used to immunize horses. Another vaccine, containing the TC-83 strain, is used on humans in military and laboratory positions who risk contracting the virus. The human vaccine can result in side effects and does not fully immunize the patient.
Unlike Eastern equine encephalitis, the overall mortality of WEE is low (approximately 4%) and is associated mostly with infection in the elderly. Approximately 15–20% of horses that acquire the virus will die or be put down. [3] There is no human vaccine for WEE and there are no licensed therapeutic drugs in the U.S. for this infection.
Vaccine for horses. In November 2012, a vaccine became available for horses. The vaccine is to be used in horses only, since, according to CSIRO veterinary pathologist Deborah Middleton, breaking the transmission cycle from flying foxes to horses prevents it from passing to humans, as well as, "a vaccine for people would take many more years."
A vaccine is available for horses. [1] This vaccine is an inactivated vaccine that uses the TC-83 strain of EEEV. [13] It is usually given in combination with vaccines for Western equine encephalitis (WEE), Venezuelan equine encephalitis (VEE), and tetanus, [4] and is also used by
Equine viral arteritis (EVA) is a disease of horses caused by a virus of the species Alphaarterivirus equid, an RNA virus. [1] [2] It is the only species in the genus Alphaarterivirus, and that is the only genus in the Equarterivirinae subfamily. The virus which causes EVA was first isolated in 1953, but the disease has afflicted equine animals ...
