Core vaccines for most horses cover tetanus and equine influenza, with others such as equine herpesvirus added based on risk. Your vet sets the schedule, usually a primary course followed by regular boosters.
The core protections
Tetanus is the one no horse should be without, as it is often fatal and horses are highly susceptible. Equine influenza is the other mainstay, especially for horses that travel, compete or mix with others. These form the backbone of most vaccination plans.
Risk-based extras
Depending on where you are and what your horse does, your vet may add equine herpesvirus, strangles or other vaccines. Competition bodies and some yards require flu vaccination on a strict timetable, so keep records up to date if you compete.
Timing and boosters
Young or newly vaccinated horses need a primary course of two or more doses, then regular boosters to keep immunity topped up. Missing a booster can mean starting the course again and may make a horse ineligible to compete, so diarise the dates.
Support recovery
Most horses are fine after vaccination, but some are quiet or a little sore for a day. Give light turnout rather than hard work that day, keep water and forage available, and monitor the injection site. A stocked first aid kit is handy for any minor reaction.
Work with your vet
Vaccination needs vary by location, age, use and disease risk, so a plan from your vet is worth far more than a generic schedule. Keep clear records, and never skip tetanus cover, which is the cheapest life-saving protection you can give.
