Vaccinations

Dr Lindsay recommends these annual/bi-annual vaccinations at minimal :

  • Eastern / Western Encephalomyelitis
  • Tetanus 
  • Rabies
  • West Nile
  • Strangles




The American Association of Equine Practitioners (AAEP) recommends that all horses receive vaccinations against rabies, tetanus, West Nile Virus, and eastern/western encephalitis. 


When does a horse need to be vaccinated? Generally, foals born to vaccinated mares should start an initial core vaccination schedule at six months old. They will need boosters when they are seven and eight months old. For the course of the horse's life, they will also need booster shots either annually or simi-annually. 


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, therefore we recommend administrating the vaccine twice a year(semiannually).

Tetanus Toxoid: 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. Rabies can be transmitted to humans. 

West Nile Virus: West Nile virus is transmitted by mosquitos. The virus causes inflammation of the brain and spinal cord. Because Long Island has a long mosquito season and the vaccine protection lasts 6-7 months,  we recommend semiannual vaccination. Horses that travel to Florida should be boostered  2 weeks before travelling. Veterinarians in problem areas vaccinate 2-4 x per year.

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.


***Vaccines are preparations of killed microorganisms, living weakened microorganisms, etc. introduced into the body to produce immunity to a specific disease by causing the formation of antibodies.

Vaccines are very delicate compounds, which if handled or administered incorrectly will be ineffective or neutralized.


Louisiana State Law: Each horse is required to have a current (with in one year) negative coggins test. Each horse shall have a brand, tattoo, or microchip as a form of identification.
