I've had a Facebook question from Rhian Jay, who raises the issue of the NHS vaccination app, and what she says is:

'Is there any idea of when the Welsh NHS vaccination app will launch please? I'm attending an event where I need proof of having had both vaccinations. Having raised it with the health board, they said that you can apply for a certificate in writing or by phone, and you can receive a certificate, but in England you can receive the vaccination through the app.'

Rhian says that she rang this morning requesting a certificate, but it's her feeling that it's archaic and slow compared to the process in England, and her question is when will we see the app in Wales. The Welsh Government said that they would be roughly four weeks behind England before it's launched, but that's about now. So, please can we have an update on that?
