Proving 1st dose for 12-15

[NotDonna]

A few people have been posting about how to obtain proof of recovery certificates and that this alongside one vaccine is enough for various EU passes. But how do I even prove my DD has had the first dose of a vaccine please? TIA

Weren't you given a vaccine card at the centre?

No and even if we were I know mine doesn’t prove anything. Over 16’s have the NHS app and a QR code. I know they are launching a pass for over 13’s once they’ve had both jabs but there’s nothing in the interim it seems.
