Summary
Corticosteroids at above-physiologic doses may blunt the antibody response to the H5N1 influenza vaccine. This could reduce protection, though the vaccine is not unsafe to give.
What this interaction means in plain words
Influenza a vaccine and Triamcinolone 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 reduces the immune response to vaccination.
What to do
Vaccinate when feasible before starting or at low steroid doses, and do not assume full protection in patients on high or prolonged doses.
What to ask your pharmacist
