Sorry if I've missed a discussion on this elsewhere, but it looks like the UK have finally made a firm commitment to help those living in the UK get their overseas vaccines recognised. The announcement is very light on details so it isn't worth holding our breath yet, but it is nice to see something more official than vague promises on twitter / hints by ministers:

Fingers crossed it does happen, as I think it would be very helpful for everyone who wants one to have access to a single document that reports all doses they have had, be they original, boosters etc.
