Gus - I'm sure you are entitled to a free 'flu jab and I also think that your carer is too.
My GP is very eager for patients over 60 or with a chronic illness to have the jab. I suppose it helps them in the longrun so hopefully, less of their patients will get ill during the winter.
They also offer a jab to keep people from getting pneumonea and other chest problems and it covers you for two years.
I wonder why some doctors and nurses are able to give these jabs without any pain at all but others make you hit the ceiling!
With best wishes.
