Confused by vaccine invite??

[BerryPieandCustard]

I have received a text message from my GP surgery inviting me to make an appointment for a COVID vaccine. The message is definitely from them as previously sent messages about appointments are on the same thread of messages.
There was a link to click which would allow me to book an appointment for as early as Tuesday the 16th feb.
I am a little confused, I am 35 years old and have no conditions that put me at risk. I take no regular medication apart from some cream for acne.
This is a mistake right? Do I book the appointment and go or try and ring them to check?

I have booked in for the appointment on Thursday.
It said on the message DO NOT PHONE THE SURGERY in capital letters so I will arrive at the appointment and see what happens. Bizarre as my husband is registered at the same surgery and is 3 years older (no pre existing issues) and he hasn’t had an invite.
Maybe if the have a surplus they are doing a kind of lottery or something

Sorry, my mistake, we haven't got to that group yet and clearly my brain isn't functioning! Have had previous posts removed to avoid any confusion or upset.

OP I think you are right to attend, good luck!
