Summary
Immunosuppressive corticosteroid doses can blunt the antibody response to vaccines. Inactivated poliovirus vaccine is not a live vaccine so there is no infection risk, but protection may be suboptimal.
What this interaction means in plain words
Dexamethasone and Poliovirus vaccine inactivated 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 suppression of lymphocyte function reduces the vaccine immune response.
What to do
Where possible, vaccinate before starting immunosuppressive steroid therapy or delay until it is reduced. Consider revaccination or serologic checks if vaccinated during high-dose therapy.
