Ms Elizabeth Canavan:

The EU is looking at this and we would like to have interoperability. I do not have an update on its exact thinking now but we would all be interested in having that system available. The Deputy is asking about our next iteration but we have been extremely focused on 19 July and getting those certificates out to everybody on which we have data. One of our next tasks is to look at the next piece but we are also hoping there would be developments at international level. Perhaps Mr. O'Connor from the Department of Health has something to add.
