The vaccines and vaccine protocols listed below are tailored to our practice and geographic location and follow the guidelines of the AAEP.

Eastern & Western Encephalomyelitis: Encephalomyelitis is caused by a virus, which is transmitted by mosquitos. The virus causes inflammation of the brain and spinal cord. The vaccine is very effective against the disease. The protection lasts 6 months.

Tetanus Antitoxin: Tetanus is a disease caused by a specific toxin of a bacillus (Clostridium tetani) which usually enters the body through wounds. It is characterized by spasmodic contractions and rigidity of some or all of the voluntary muscles (especially of the jaw, face and neck). The bacteria is found in horse manure. The vaccine is very effective and administered once yearly. The vaccine is boostered in case of laceration, surgery, or penetrating wounds.

Rabies: Rabies is a viral disease that infects the nervous system of mammals. It is transmitted through contact with the saliva of infected animals. It is 100% fatal. The vaccine is given once yearly and is very effective.

West Nile Virus: West Nile virus is transmitted by mosquitos. The virus causes inflammation of the brain and spinal cord. The virus is transmitted from infected birds by mosquitoes. Humans and horses appear to be especially susceptible. Studies done by the U.S. Department of Agriculture show that infected horses will not transmit WNV to other horses or to people. However care should be taken when handling blood from suspect animals.

Symptoms of disease caused by WNV may include the following:

  • * Flu-like signs (fever and depression)
    * Skin twitching, especially around the muzzle.
    * Hypersensitivity to touch and sound
    * Driving or pushing forward without control
    * Incoordination

Because permanent neurological problems and death can occur, early recognition and initiation of treatment is important. No specific treatment protocol exists however most cases will resolve with supportive therapy and anti-inflammatories.

Rhinopneumonitis: Rhinopneumonitis is a herpes virus which causes respiratory infections, abortions, and inflammation of the spinal cord. The vaccine is not 100% effective and the protection only lasts 10-12 weeks. Pregnant mares should be vaccinated at 3.5, 7 and 9 months from the breeding date. Horses that are travelling to shows, races, sales, etc. should be vaccinated every 3 months. Pleasure horses that do not travel should be vaccinated twice a year. The vaccine does not protect against the neurologic form of the disease.

Influenza: Influenza is a virus that causes high fever and respiratory infection. The vaccine is not 100% effective, and the protection lasts only 10-12 weeks. Horses travelling to shows, sales, racing events, etc. should be vaccinated every 3 months. Horses that do not travel should be vaccinated at least twice a year.

Strangles: Strangles is a bacterial disease caused by Streptococcus equi. It is highly contagious and causes the following signs: high fever, abscessed lymph nodes, and respiratory infection. Horses may develop guttural pouch infections, sinus infections, purpura hemorrhagica, laryngeal paralysis, and bastard strangles. There is an intranasal vaccine which is more effective than the intramuscular vaccine. The vaccine is given once a year except in endemic barns (that have frequent outbreaks) where semiannual vaccination is recommended.
