Thank you very much indeed for that answer, and further to your oral statement on this issue of 2 October and moving forward, obviously, generic PrEP drugs are cheaper than the current branded ones in issue. Would you agree that if there are any savings to be made from any such future switch to generic PrEP drugs, such savings would be well-used in actively promoting PrEP to groups who are not accessing it in the numbers we might expect at the moment?
