According to my GP they had a batch for the over 65s but they ran out pretty quickly. I usually get free flu jabs due to asthma but although it's strongly recommended I'm not aware of it being a definite priority group.
Suggest trying again with your GP. I'm also in a lower-priority group and didn't get the jab during the first round, but my local surgery contacted me later when stocks had been replenished.
Aside: It was, for the NHS, an exceptionally efficient process. I was given an exact time slot and was in and out in less than three minutes.
