I agree. He has been a fantastic Type 1 ambassador.
But he has a right to make his own decision about the jab.
Shame he has decided not to take at the moment but I can see his point about not having information about long term affects and he has to be a fit chap so he will not be overweight, his HbA1C has to be in range to play rugby and he is unlikely to have any other comorbidities so he is not in the highest at risk categories.
Unfortunately, some people will not be able to separate his fitness from his decision not to take the jab, At least he has not been spreading misinformation.
