A neighbour had the opposite on Friday. He hadn't been called and asked his wife to check what was going on when she was getting her jab. Health Centre said tell him to keep his phone on, we may call at about 2pm. 2 pm phone rang, 2:15 jab administered. He asked when do I come back...answer...same day as your wife.
It's interesting...I only realised that the restrictions in Spain are still lighter than the UK even though the UK has opened up and the vaccine percentage is lower in Spain.
