Ms Elizabeth Canavan:

The first thing to say is that, as the Senator knows, we have very high rates of sign-up. We are anticipating that persons over a certain age who have recovered will have taken up their offer of a vaccine. We have very high take-up at the moment. The over-50 age group will have had the opportunity to schedule a second dose of the vaccine by the end of this week. I do not know if Mr. McCallion wants to say anything about whether we have tried to make compare the data sets.
