I think there were three questions within that, the first about the time between doses. The advice I've had is four weeks. We'll continue to examine whether it can be shortened to enable us to have more rapid delivery of both the doses of the current Pfizer vaccine that has been given approval for supply.

On the Welsh immunisation service, as I said in the statement, that can automatically schedule second doses and send out appointment letters, and so we will be able to send people that reminder. And of course, they'll also, as was discussed with your colleague, have a physical reminder, with an appointment card as well. So, there will be opportunities to remind people. And again, because this is going to be such a significant exercise, I think it will be very difficult to avoid the wider public communication about the reality of the vaccine delivery, and I'm confident that, not just in the first few people who are having the vaccine, but then the first few people who are then coming back for their second dose, they'll be interested in those, and then, in the week following, when they should then have the fullest coverage and protection, to understand what that has meant for the services that they either work in, or how they're able to live their lives. 

I'm sorry, I appear to have forgotten your third question, because you asked three in a row.
