    Some facts from a very interesting website - http://www.tbfreeengland.co.uk/vaccination/

    These are just some extracts, worth going to the website for a full read as it also gives reference to the original scientific research on which the statements are based.

    --------------------------------------------

    Vaccination won't work on an animal that already has bovine TB, and no country in the world where wildlife carries the disease has eradicated it in cattle without tackling it in wildlife too.

    There are calls for cows to be vaccinated against bTB.

    However there is no legal vaccine available. Currently the only option is the BCG vaccine (Mycobacterium bovis Bacille Calmette-Guérin).

    The problem is that at present it is impossible to distinguish between a BCG-vaccinated and TB-infected cow. And for this reason it is currently illegal under EU law to vaccinate cattle with the BCG jab.

    The science suggests the vaccine is most effective in very young animals, and less so in older subjects. Young badgers spend their early weeks in the sett, making it impossible to trap and vaccinate them and putting them at risk of infection before they emerge.

    There is also no evidence as yet which shows that vaccinating a proportion of the badger population actually results in a reduced risk to cattle.

    An oral bait vaccine is likely to offer the most successful route forwards. But this option is still some years away from becoming a part of any badger control plan, because there is no licensed or proven oral vaccine currently available.
