Could your horse or pony be eligible for the vaccine trial?
The Animal Health Trust is launching a ground-breaking nationwide trial of a vaccine for the prevention of Equine Grass Sickness (EGS). The current theory is that EGS is a toxico-infectious form of botulism caused by Clostridium botulinum type C. This vaccine trial will follow 1100 horses and ponies for two years. Half of the horses and ponies on the trial will be vaccinated with a Clostridium botulinum type C vaccine; the other half of the horses and ponies will receive an inactive placebo injection, and the incidence of EGS will be compared between the two groups.
If your horse/pony:
- Has a valid horse passport
- Lives on a premises that has had at least one case of EGS in the last two years
then you may be eligible to participate in the vaccination trial.
