Our Services - Vaccinations

Vaccinations are an important part of your horse's routine health care and it is the responsibility of the owner or trainer to ensure that their horse meets the requirements demanded by the event organising authority for any event in which they wish to compete.

Below are timings for commonly used vaccination programs, but please note that some organisations require vaccinations to be given more often. The practice provides a reminder service free of charge to all our clients.


Every horse and pony should be protected against Tetanus. If not combined with Influenza vaccination (see below) then the initial Tetanus vaccination course consists of two injections, 4 to 6 weeks apart. Thereafter, boosters are given every 2 years.

Flu & Tetanus

  • 1st vaccination - to be given after 5 months old
  • 2nd vaccination - to be given 28-92 days after the 1st vaccination
  • 3rd vaccination - to be given 150-215 days after the 2nd vaccination
  • Booster vaccination - to be given annually (within 365 days)

Flu & Tetanus in Pregnant Mares & Foals

Pregnant mares should be given a booster vaccination 4-6 weeks before foaling so that passive immunity is passed to the foal via the mare's milk. These protected foals should start their primary course at 5 months of age.

Unprotected foals should be protected with an injection of Tetanus antitoxin serum within 24 hours of birth.

Other Vaccinations

Equine Herpes Virus

To provide effective immunity against abortion caused by EHV 1 & 4, a course of three vaccinations must be given during the 5th, 7th, and 9th months of pregnancy.

To provide effective immunity against respiratory disease caused by EHV 1 & 4 a primary course of 2 vaccinations must be given. Following this primary course a booster vaccination must be given every 6 months.


Vaccination of pregnant mares provides protection for foals against rotavirus (this is a major cause of diarrhoea in foals).

Pregnant mares should be given three doses of vaccine at the 8th, 9th and 10th month of each pregnancy.
