Apologies if this is already posted.
I checked The Green Book for eligibility for the Spring Booster, and as well as over 75 age, there is also this. 'Those requiring long term immunosuppressive treatment for conditions including.........rheumatoid arthritis' (Table 3)
So I phoned a local pharmacy to ask what proof I needed, explaining that I'm age 72 and on 20mg Mtx. And have never been classed CEV. They have booked me in for later next week, and said all my info would be available to them online (tho I will take a copy if my repeat prescription just in case!)
I'll let you know if anything goes wrong, but assuming it won't
