Whinny’s Wisdoms

Springhill Equine Veterinary Clinic

Hey everybody, it’s your favorite clinic mouse Whinny here! Everyone knows their horses need to be vaccinated, but not everyone knows what we’re vaccinating for, and why it’s so important to stay on schedule. The health and longevity of our equine friends is a priority for every responsible horse, pony and donkey owner, so today we’re going over the core vaccines.

Core vaccines, designed to protect against specific and potentially life-threatening diseases, play a crucial role in achieving this goal. There are five key core vaccines for horses: Eastern Equine Encephalitis (EEE), Western Equine Encephalitis (WEE), Tetanus, West Nile Virus (WNV), and Rabies.

  • Eastern Equine Encephalitis (EEE) and Western Equine Encephalitis (WEE): EEE and WEE are viral diseases transmitted by mosquitoes that affect the central nervous system of horses. Symptoms of both diseases can start with a fever and lead to severe neurological symptoms, emphasizing the importance of vaccination. Neurologic symptoms can range from severe onset of stumbling, depression and seizures. Unfortunately in the case of EEE cases are often fatal. Vaccination against EEE and WEE is vital, especially in regions where mosquitoes are prevalent and should be boostered every 6 months after they have had their primary vaccination series as a foal.
  • Tetanus: Tetanus is caused by the bacterium commonly found in the soil, Clostridium tetani, and is contracted through wounds or injuries. Tetanus can result in muscle stiffness, difficulty swallowing, and even death. Tetanus vaccination is a cornerstone in equine healthcare, preventing this potentially fatal disease. Boosters are typically administered every 6 months.
  • West Nile Virus (WNV): WNV is a mosquito-borne viral infection affecting the central nervous system. Infected horses often have a fever and may exhibit neurological signs, such as incoordination, circling, muzzle twitching and others. Vaccination against WNV is recommended, particularly in areas where the virus is prevalent. Biannual boosters help maintain protection.
  • Rabies: Rabies is a viral disease that affects the central nervous system and is zoonotic. A disease being zoonotic means that it poses a risk to humans. Rabies symptoms can be varied, especially in equines and the disease is almost universally fatal. Unlike in dogs where rabies presents with excess salivation and aggression, in horses symptoms can be as non-descript as colic, lameness or depression. Rabies vaccination is essential for both equine and human health. Horses should receive regular yearly boosters as part of a comprehensive vaccination plan.

Whinny Wisdom: The EEE vaccine is nearly 100% effective at preventing the disease, but only for six months. If you have mosquitos for more than six months a year, your horse needs two boosters every year! Horses can get EEE seven months after their last vaccine, so there’s no grace period.
