When your horse gets sick, everything comes to a halt. Why take the risk?

Make vaccination part of your routine.

Why do we vaccinate horses?

Vaccination makes sense for every horse. Diseases are easier and far less expensive to prevent than treat. Vaccination may even reduce the risk of permanent damage or death that can result from certain diseases.

Horses contract infectious diseases in two ways – the environment and other horses. Your horse may be at less risk if it lives in isolation, but even horses that don’t come into contact with other horses may not be free from risk of disease.

Veterinarians are able to select from a broad range of vaccines and can provide you with guidance on what vaccines are most appropriate and when they should be administered.

Are there any side effects to vaccination?

Administering any foreign material always presents some risk of side effects. With vaccines, the risks are often minor and have to be measured against the potential risk of contracting the disease(s).

Occasionally, horses and ponies experience mild and temporary side effects.

Possible side effects include:

  • Localized muscle soreness and/or swelling
  • Fatigue
  • Fever
  • Loss of appetite
  • Lack of energy or alertness

These signs are perfectly normal and are evidence that an immune response has been stimulated.

In rare cases, more serious side effects can occur. Overreaction of the immune system may lead to hives, difficulty breathing, colic and even collapse.

Any vaccinated animal should be monitored closely for the first hours after receiving a vaccine or other immune stimulant. If any abnormal reaction is observed, call your veterinarian immediately.

Vaccines are safe and efficacious as long as label directions are followed. Some vaccines have restrictions regarding minimum age of the foal or use in pregnant mares. Read the label closely and follow your veterinarian’s recommendations and instructions.

Core vaccines

Eastern/Western Equine
Encephalomyelitis (EEE/WEE)

Equine encephalomyelitis is a mosquito-borne, viral infection that can cause severe inflammation of the brain and spinal cord in horses and humans.

Clinical signs can include:

  • Behavioural changes
  • Loss of appetite
  • Dementia with head-pressing
  • Fever
  • Lack of coordination
  • Teeth-grinding
  • Blindness
  • Circling

Tetanus

Tetanus occurs when a wound becomes infected with bacterial spores of Clostridium tetani.

Clinical signs can include:

  • Spasms of the muscles (often jaw)
  • Rigid paralysis
  • Respiratory paralysis
  • Anxious expression
  • Reaction to noises or movements with spasms or convulsions

West Nile Virus (WNV)

West Nile Virus causes encephalomyelitis (inflammation of the brain and spinal cord)

Clinical signs can include:

  • Lack of coordination
  • Stumbling
  • Loss of appetite
  • Fever
  • Muscle weakness
  • Partial paralysis
  • Neurologic signs may include head-pressing, inability to stand up, convulsions and possibly death

Rabies

Rabies is a viral disease that can infect virtually all species of mammals (including humans)

Clinical signs can include:

  • Colic
  • Lack of coordination
  • Muscle spasms
  • Blindness
  • Lameness
  • Incontinence
  • Paralysis
  • Depression

Risk-based vaccines

Influenza (EIV)

Equine influenza, or flu, is an acute viral infection similar to the human flu.

Equine Herpesviruses 1 and 4 (EHV, also called Rhinopneumonitis or Rhino)

Equine herpesvirus is a viral infection caused by either equine herpesvirus 1 (EHV-1) or equine herpesvirus 4 (EHV-4). Both viruses can cause a mild respiratory infection similar to influenza.

Strangles (Streptococcus equi)

Strangles is a highly contagious respiratory and lymph node disease caused by the bacterium Streptococcus equi.

Potomac Horse Fever (PHF)

Potomac horse fever is an acute bacterial infection caused by the organism Neorickettsia risticcii, a bacteria present in freshwater snails that is believed to be transmitted to horses through the ingestion of infected aquatic insects.

Equine Viral Arteritis (EVA)

Equine viral arteritis is a viral disease that can cause abortions in pregnant mares.

Anthrax

Anthrax is a rare bacterial disease that strikes suddenly, resulting in extremely acute hemorrhagic disease and death within one to two days.

Botulism

Botulism is a disease that occurs when toxins from the Clostridium botulinum bacterium are ingested.
