Summary
Live zoster vaccine can cause disseminated vaccine-strain varicella in immunosuppressed patients, and corticosteroids may reduce the vaccine response. Fludrocortisone at replacement doses poses a lower risk than glucocorticoids.
What this interaction means in plain words
Fludrocortisone and Zoster vaccine live can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Corticosteroid immunosuppression impairs control of live attenuated varicella-zoster virus and reduces immunogenicity.
What to do
Assess total corticosteroid exposure; if immunosuppressive doses are in use, defer vaccination or use the recombinant non-live zoster vaccine where available.
