There is no such thing as an unofficial carer. If you are providing physical and/or emotional care to another person. You are a carer. And it's not about queue jumping.I am an unofficial carer for my partner,
If your partner agrees you can be added as her carer. At her G.P.'s you need to be registered so the G.P. practice can add you to the list for the vaccine.
