Summary
Immunosuppression from azathioprine may blunt the antibody and cellular response to the recombinant zoster vaccine, leaving patients less protected. Because it is non-live, it is not infectious, so safety is not the main concern.
What this interaction means in plain words
Azathioprine and Zoster vaccine recombinant have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Azathioprine inhibits lymphocyte proliferation, reducing the immune response to vaccine antigen.
What to do
Vaccination is still recommended in immunosuppressed patients; where possible, time doses when immunosuppression is lowest. Do not delay vaccination unnecessarily.

- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
