I don't consider my t1 diabetes as chronic. However corona virus may disagree....
After the PM’s speech The chief medical officer said that you are classed as vulnerable if you are eligible for the NHS flu jab - which I think is all diabetics.
Since I left the NHS to change the direction of my working life, well over 10 years ago, I have never been invited to have a flu jab, although I did volunteer to have it for a few years.
On that basis, I'm not at any mother risk than any other Joe Soap, it seems.
