Dr. Damien Barrett:

We have the evidence and trial work, which has shown it is on a par with culling. One needs to bear in mind we need to get penetration of the badger population and have sufficient numbers of the badger population vaccinated. That is why we sent out those texts to which the Senator referred. We need to know where the badgers are to vaccinate them. That is the challenge. It is not a small body of work, going through the byroads of the country.
