Yes, I have seen the views of Fiona Reynolds and others, and I take them very seriously. The use of ring vaccination has been considered, including as a method of damping down the disease. At present, the view is that it would not give us the same benefits as the present policy of 24–48 hours. As the House has heard, there are indications that the policy is beginning to bite into the outbreak, anti we must take that into account. We are keeping our options open and we are trying to evaluate the best way of using vaccines and non-vaccine approaches.
