Dr. Lucy Jessop:

In terms of reduction of transmission, as far as I am aware there is not any new data as yet so we will be keeping a close watch on that. There were tens of thousands of people in the studies, obviously, but that would not have been enough to be able to pick up whether it reduced transmission now that several countries are quite far on with their vaccination programmes. Some of that data will be becoming available and we will be updating our information as soon as we have more data around that.
