Man on the radio just now saying that he had been amazed to get a vaccine invite as he's not in the groups being contacted at this time. So he rang his GP to enquire. They looked into it and came back to him.
They had made a mistake in recording his height. Instead of recording it at 6 foot 2 inches they had entered 6.2 centimetres. The result was that his BMI was calculated at around 28000
He declined the vaccine invite for the time being so that someone else could have it.
