Not the same but know of GP practice that gives out the Astrazeneca vaccine. They have to mix the vaccines in the morning, people who have been invited come in, so your over 70s. At the end of the day if anyone didn't come in there's left over vaccines that need to be used then because they've been mixed so the staff have been giving the left overs to family members. If it keeps happening then they'll likely invite me in to use up a leftover in the next month. If you have a letter its too much of an administrative mess for them to call them in earlier to take any left overs.
