The earliest projected date for the use of a BCG cattle vaccine with a DIVA test to Differentiate Infected from Vaccinated Animals is 2015.
It should be noted that in addition to the science, there are a number of key policy, legal, commercial, regulatory and manufacturing issues surrounding the implementation of a vaccine against bovine TB.
The possible future use of cattle vaccines has been discussed with the European Commission and the Commission has indicated that an accredited DIVA test will be critical for a cattle vaccination policy. DEFRA will continue to work closely with the Commission and other member states to minimise the time required to make the required legislative changes once the necessary scientific information is available.
