The article discusses the factors that can compromise a horse’s immune system, such as poor nutrition, excessive exercise, chronic stress, and prolonged environmental exposure. The lack of immunity transfer during pregnancy makes newborn foals vulnerable at birth, but this does not seem to have long-term effects on their health. Horses have a shorter and less robust immune response to vaccines compared to humans, leading to the need for more frequent boosters.

The equine immune system requires more frequent vaccinations due to exposure to infectious agents from other animals, insects, and the environment. It is recommended to work with a veterinarian to ensure horses are on a proper vaccination schedule, including core vaccinations and additional risk-based vaccines depending on exposure risk. Some owners choose to have antibody titers checked before administering boosters, but annual or biannual vaccinations are generally recommended for most horses.

The article emphasizes the importance of maximizing the protective effects of vaccines for horses, especially those that travel to events or interact with unfamiliar animals and environments. Working with a veterinarian to establish a proper vaccination schedule and following the guidelines provided by the American Association of Equine Practitioners can help ensure a horse’s immune health is optimized to fight off diseases effectively.
