Summary
Systemic corticosteroids suppress immune function and may blunt the antibody response to influenza vaccination. This can leave the patient with less protection than expected, although the inactivated vaccine remains safe to give.
What this interaction means in plain words
Dexamethasone and Influenza virus vaccine trivalent adjuvanted 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-mediated immunosuppression reduces the immune response to vaccine antigen.
What to do
Vaccinate before starting prolonged or high-dose dexamethasone when feasible; otherwise still vaccinate and consider the potentially reduced protection when assessing influenza risk.
