Apologies. We have been in and out of the Seanad voting a couple of times. I have read all of the submissions and heard most of the opening presentations but I might not have heard all of the questions, so if I repeat something, the Chairman might let me know. Much of what I was going to ask has been covered anyway.

Is there a medical reason for a 48-hour antigen test versus a 72-hour PCR test? Why has one a shorter window than the other?
