Vet Intervals: Taking the Guesswork Out of Equine Vaccination Dates
For equine vets, calculating vaccination intervals is a familiar part of everyday practice. It sounds simple: check the passport, count the days and confirm that the horse is compliant. In reality, different competition rules, primary vaccination courses, booster intervals and upcoming competition dates can make this surprisingly time-consuming—and getting it wrong can have significant consequences.
At WebVet Ltd, we developed Vet Intervals to make these everyday calculations quicker, easier and less prone to error.
Vet Intervals is a mobile app designed for veterinary surgeons, horse owners and others working within the equine industry. Among its features are a Days-Between Calculator, Age Calculator, Unit Converter and Equine Vaccine Planner, providing quick access to calculations that vets regularly need in practice.
Why do vaccination intervals matter?
Equine influenza vaccination is important not only for the individual horse but also for the wider equine population. Vaccination remains a fundamental component of preventive healthcare, particularly where horses regularly travel, mix and compete.
For competition horses, however, vaccination is also an eligibility issue. Horses competing under racing or equestrian governing bodies may need to satisfy specific vaccination requirements before they can compete. These requirements can differ between organisations and have changed over time.
The practical consequences of an incorrect date can therefore extend well beyond having to rearrange a vaccination appointment. A horse with a non-compliant vaccination history may be unable to compete.
This is relevant at every level of equestrian sport from local shows and Pony Club or Riding Club activities through to national competition, racing and international events.
Making life easier for vets and owners
Checking vaccination records often involves manually counting days between dates, checking the permitted window and then working out the most appropriate date for the next vaccination.
Vet Intervals is intended to simplify that process.
The Days-Between Calculator quickly determines the exact interval between two dates, while the Equine Vaccine Planner helps users plan future vaccination dates around applicable regulatory requirements. For a busy ambulatory vet working through multiple passports, removing repetitive manual date calculations can save valuable time.
It can also make communication with owners easier. Rather than simply saying that a vaccination is “due in a few months”, the next vaccination can be planned with the horse’s competition calendar in mind.
Vaccination is also about biosecurity
Compliance is only part of the picture. Horses travelling to shows, races and other events mix with animals from many different yards and geographical areas. Maintaining appropriate vaccination programmes therefore contributes to broader infectious-disease prevention and population-level protection.
No app replaces veterinary judgement, and the relevant governing body's current regulations should always be checked when determining competition eligibility. Vet Intervals is designed instead to make the calculations behind those decisions faster, simpler and more convenient.
For vets, that means less time counting dates. For owners, it means clearer planning. And for horses heading to their next local show, national championship or international competition, it can help prevent an avoidable vaccination-date problem from getting in the way.
