Question: are cows vaccinated against tb?
Answer: 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 – ref 1,2,3,4,5). The problem is that at present it is impossible to distinguish between a BCG-vaccinated and TB-infected cow.
