Field trials of a bovine vaccine and a new skin test for bovine tuberculosis have begun in England, the Animal and Plant HEALTH Agency (APHA) has announced
The world's first clinical field trials of a BCG vaccine and a DIVA skin test have started on a cattle farm in Hertfordshire.
The skin test that will accompany the vaccine will allow veterinarians to identify cattle that have been vaccinated and those that are infected with the disease - something that has not been possible until now.
If the field trials are successful, farmers will be one step closer to being able to vaccinate their animals against bovine TB.
The disease is regarded as the most difficult and intractable animal health problem farmers face today, costing taxpayers an estimated £100 million annually.
More than 36,000 cattle in England and Wales had to be slaughtered last year to deal with the problem, and the UK is developing a cattle vaccine with a goal of introducing it by 2025.
In December, APHA awarded a contract to Eville & Jones to conduct clinical field trials in cattle, the culmination of more than 20 years of research at the agency.
In a joint statement, the chief veterinarians for England, Scotland and Wales said the start of this groundbreaking field trial will be welcome news for many farmers.
They said manufacturers have "been hit hard by this disease and look forward to this important step forward in our efforts to deploy a working cattle vaccine by 2025."
“If successful, this world-leading project could lead to the first-ever deployment of a bovine bTB vaccine and DIVA skin test,” the veterinarians said.
"This will contribute to a game-changer in the fight against this terrible disease that is affecting many countries around the world."
In the event that the initial trials are successful, the study will then be expanded to more farms as part of its second phase to test both the bovine BCG vaccine and the DIVA skin test together.
The goal is to gather sufficient evidence to support an application for marketing authorization with the Veterinary Drugs Administration for the use of both products in the UK.
