<p>In the comprehensive TB Strategy we commit to pursuing options to license a cattle
vaccine by 2023, or sooner if possible, but the hurdles remain very high. The 10 years
indicative timeline set out by the Commission was an indication of the timescale for
allowing free movement of vaccinated cattle in the EU. It may be possible for vaccination
to be used in the UK before then but we are still some way from that, given the need
to develop an effective DIVA test (a TB test to differentiate infected from vaccinated
animals) and, if we are successful in that, what would then inevitably be lengthy,
wide-scale and expensive field trials.</p><p> </p>
