Just that really. I'm on an immune-suppressing biologic drug for auto-immune disease(s), and after a bit of a tussle with my GP surgery <waves, and thanks> I finally got jabbed with Shingrix #1 this morning. 
Next one (2 of 2) is in 8 weeks.
Please may I encourage anyone in the same category as me - immune-suppressed and over 50 years old - to take advantage of this vaccine programme that was introduced by the NHS on the 1st September this year. Boots do offer it privately but the cost for the course is £450 thus prohibitive for many. The NHS jabs via your GP are free. You must go through your GP to receive the jabs for free. This is not an active vaccine and is safe for immune-suppressed people.
Please don't wait to be called in. My GP surgery is having some real time and admitted issues with flagging up patients on immune-suppressing biologics on its (new-ish) data system. If in doubt, ring and explain.
I'm happy to help to look up anyone's meds for them in the 'Green Book'. Mine is Adalimumab, a commonly used TNF-blocker for psoriasis and psoriatic arthritis that for some reason my GP surgery didn't recognise or compute.
