I'm in my late 50s and have been offered a shingles vaccine by my surgery, I assume because I have MGUS + an abnormal light chain ratio and am considered immunocompromised.
I wasn't sure I'd had chicken pox as a child, so had a blood test (Varicella-zoster IgG level), the result of which "indicates previous exposure and therefore immunity." This is a bit confusing to me; if I have "immunity", why do I need the vaccine?
