English: On your final question about fertility treatments, I'd need to go through more of the detail. If you'd be happy to send me a note, I'll be happy to provide you with some more detail on the points that you raise. In terms of people undertaking a variety of vaccination programmes, the point I made earlier stands, that we don't anticipate there being, at this point in time, a challenge with vaccine supply for other vaccines. The real challenge is getting the public to take up the vaccinations that are available, and to recognise the very real protection it provides to them and other people if they do so. On your point about testing centres, it's not a surprise, but it's a constant source of frustration and disappointment to me that we have reports in other organs claiming to look at the UK-wide picture that don't accurately reflect where we are in Wales. We of course have more than one testing centre - we've got more than one drive-through centre - and the 21 that NWIS have provided you reflects not just the numbers of venues, but then there's something about the spread of those as well, because community testing involves people going out to people's homes. I've already said we're going to be at the point where we're going to have home testing available for people as well, and mobile units to go out and provide testing too. So this isn't just about getting people to a test centre; it's actually about getting the tests to people in a more convenient way. That isn't just an issue for rural Wales; it's an issue for large parts of urban Wales too, to make the testing programme as easy to access as possible. It's not just about the form-filling process, but then the practical access to the test itself, and we actually should then be in a world where we're able to move to a point where the test results themselves are sent directly to people by SMS if they have that. I think that texting response will remove yet another part of the challenge in the efficiency of the system. So, yes, NWIS are correct with their 21, but you need to see how those 21 different programmes and venues work in providing tests to people, and not just getting people to a different venue.
Welsh: O ran eich cwestiwn olaf am driniaethau ffrwythlondeb, byddai angen imi graffu ar ragor o'r manylion. Os ydych chi'n fodlon anfon nodyn ataf, byddaf yn fwy na pharod i roi rhagor o fanylion ichi am y sylwadau yr ydych chi'n eu crybwyll. O ran pobl yn ymgymryd ag amrywiaeth o raglenni brechu, mae'r sylw a wneuthum yn gynharach yn awgrymu nad ydym yn rhagweld, ar hyn o bryd, y bydd her o ran y cyflenwad o frechlynnau yng nghyswllt brechlynnau eraill. Yr her wirioneddol yw cael y cyhoedd i gymryd y brechiadau sydd ar gael, ac i gydnabod y diogelwch gwirioneddol y maen nhw'n eu darparu iddyn nhw a phobl eraill os byddant yn gwneud hynny. O ran eich sylw am ganolfannau profi, nid yw'n syndod, ond mae'n ffynhonnell gyson o rwystredigaeth a siom i mi fod gennym ni adroddiadau mewn sefydliadau eraill yn honni eu bod yn edrych ar y darlun ledled y DU nad ydynt yn adlewyrchu'n gywir y sefyllfa yng Nghymru. Wrth gwrs, mae gennym ni fwy nag un ganolfan brofi - mae gennym ni fwy nag un ganolfan profi drwy ffenest y car - ac mae'r ffigur o 21 y mae Gwasanaeth Gwybodeg GIG Cymru wedi ei roi i chi yn adlewyrchu nid yn unig nifer y lleoliadau, ond wedyn mae rhywbeth am ledaeniad y rheini hefyd, oherwydd mae profi cymunedol yn golygu bod pobl yn mynd allan i gartrefi pobl. Rwyf eisoes wedi dweud y byddwn yn cyrraedd y man lle byddwn yn profi pobl yn eu cartrefi hefyd, a bod unedau symudol ar gael i fynd allan a darparu profion hefyd. Felly nid mater o gael pobl i ganolfan brawf yn unig yw hyn; mewn gwirionedd, mae'n ymwneud â chael y profion i bobl mewn ffordd fwy cyfleus. Nid mater i Gymru wledig yn unig yw hynny; mae'n fater i rannau helaeth o ardaloedd trefol Cymru hefyd, i wneud y rhaglen brofi mor hawdd ei defnyddio â phosib. Nid yw'n ymwneud yn unig â'r broses o lenwi ffurflenni, ond wedyn pa mor ymarferol yw gallu cael y prawf ei hun, a dylem mewn gwirionedd fod mewn byd lle gallwn ni symud i sefyllfa lle caiff canlyniadau'r profion eu hunain eu hanfon yn uniongyrchol at bobl drwy neges destun os yw hynny'n bosib. Credaf y bydd hysbysu drwy negeseuon testun yn dileu rhan arall o'r her o ran effeithlonrwydd y system. Felly, ydynt, mae Gwasanaeth Gwybodeg GIG Cymru yn gywir gyda'u 21, ond mae angen i chi weld sut mae'r 21 o raglenni a lleoliadau gwahanol hynny'n gweithio o ran darparu profion i bobl, ac nid dim ond cael pobl i leoliad gwahanol.
