Johne's disease: how to spot and report the disease
Advice on what to do if you suspect there is an outbreak of this infectious disease.
Vaccination against Johne's disease
In Britain there is a vaccine, however it is only suitable in limited situations. Consult your veterinary surgeon to see if this may be worthwhile for your premises. However it does not remove the infection from the herd.
Animals that have received the vaccine react to the avian component of the tuberculin test, which complicates the interpretation of the herd bovine tuberculosis test, so the herd history of vaccination and Johne’s status should be given to the vet conducting a TB test.
Use of the vaccine interferes with the Johne's disease blood test, particularly where animals are tested at two years of age. A vaccination programme will have most effect where it is combined with a management programme. You should seek the advice of your veterinary surgeon in making a decision, and update your herd health and welfare plan accordingly.
