Dr. Siobh?n N? Bhriain:

I thank the Senator for his comments. I will ask a number of my colleagues to respond. I ask Dr. Igoe and anyone else who wishes to contribute to talk about primary prevention. I ask Dr. Browne to answer the question about the lack of evidence of increased availability. I ask Dr. Lyons to comment on why we are waiting until 17 October and if Dr. Igoe also wants to contribute on that, that will be fine. I ask Dr. Browne to discuss the issue of supply chains and Dr. Lyons to comment on PrEP. I will hand over to Dr. Igoe first to comment on primary prevention.
