Summary
The anthrax vaccine is non-live, so it can be given safely, but immunosuppressive prednisolone doses may reduce the antibody response. Protection may be lower than expected.
What this interaction means in plain words
Anthrax vaccine and Prednisolone 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 suppression of lymphocyte function reduces vaccine-induced antibody production.
What to do
Proceed with vaccination when indicated, particularly after exposure, and complete the full schedule. Consider vaccinating before starting prolonged high-dose steroids when feasible.
