Experts from New Zealand are among those in Cardiff for a conference hosted by the Welsh Government on the possible use of cattle vaccination to eradicate bovine TB.
Cattle vaccination is not currently allowed under EU legislation, because the best vaccine interferes with the main diagnostic test used to establish if herds have tuberculosis.
More than 1,400 badgers have so far been vaccinated under the Welsh Government's pilot programme to tackle bovine TB, which is being carried out in north Pembrokeshire, and parts of Ceredigion and Carmarthenshire.
Welcome to our international delegates, here to consider how cattle vaccination could contribute to TB eradication. #TBvaccwales
