It seems that the word “drekly” is catching on in the House. I will deal with oral vaccination later. Right now, only the injectable BCG is available to tackle bovine TB and it does not fully guarantee protection. Some animals will be fully protected, some will benefit from a reduction in the disease, but some will get
no protection. That is a shortcoming of a vaccination policy, but it would be a useful addition to the toolkit and we will use it to tackle the disease when we can perfect it.
