Tetanus is a fatal disease caused by a bacterium present in soil. Vaccinations for tetanus (without influenza) are given every two years after the primary vaccination course.
Equine influenza (flu)
Flu is caused by a virus which is spread by the respiratory route. The necessary vaccination schedule is as follows:
- A primary course of two injections 21-92 days apart (three weeks to three months).
- A third injection 150-215 days after the second injection (five to seven months).
- Annual boosters no more than 365 days after the previous injection. Horses that compete under FEI rules must be vaccinated every six months.
This is caused by a virus which can cause respiratory disease, neurological disease and abortion. Vaccinations provide protection, and are given every six months after the initial course and can be given at the same time as influenza and tetanus vaccinations. In pregnant mares, vaccination is recommended at five, seven and nine months of gestation.
