More than 5,000 doses of badger vaccination have been administered to animals in west Wales over the past four years.
When the project began, the area had been identified as having some of the highest rates of incidence of TB in Europe.
Rebecca Evans, the Welsh deputy minister for farming and food, said the aim was to develop a degree of immunity to bovine TB within the badger population, which should, in time, reduce the potential for the onward spread of infection to cattle and other badgers in the area.
“We know it may take years to properly see the benefits of some of our additional measures in the area, which includes six-monthly testing and badger vaccination,” she said.
The vaccination work is undertaken in cycles and will continue until the end of October. It is being carried out over seven vaccination cycles, each of which lasts four weeks – the first three weeks involve liaising with the landowner and preparatory work, with vaccination taking place in the final week.
A report comparing levels of bovine TB in herds in the IAA with herds in other parts of Wales has also been published and is available at http://bit.ly/1i6FETc
