Last updated
For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.
Summary
Live vaccinia vaccine can cause progressive vaccinia and other serious complications in immunocompromised individuals, and corticosteroid therapy increases this risk while reducing vaccine response.
What this interaction means in plain words
Smallpox vaccine live and Triamcinolone are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Why it happens
Corticosteroid immunosuppression permits uncontrolled replication of vaccinia virus and weakens vaccine response.
What to do
Avoid vaccination during immunosuppressive corticosteroid therapy except when exposure risk clearly outweighs harm, and then only with specialist advice. Defer until therapy is stopped or reduced to non-immunosuppressive levels.
