A hundred horses and ponies in the UK's equine grass sickness hotspots will be vaccinated against the deadly disease this winter.
A full trial of at least 1,000 horses and ponies is planned for 2013-14.
Equine grass sickness is a neurological disease of unknown cause that paralyses the digestive system.

Grass Sickness is a devastating disease of horses, ponies and donkeys in which there is damage to parts of the nervous system which control involuntary functions, producing the main symptom of gut paralysis.
It occurs almost exclusively in horses with access to grass and is invariably fatal.
American readers may not be familiar with this disease, which is found in Great Britain and has been the subject of arduous research for years.
It sounds like the research is bearing some fruit.
