Summary
Higher-than-physiologic doses of corticosteroids can weaken the immune response to the adjuvanted H5N1 vaccine. Protective antibody levels may be lower than expected.
What this interaction means in plain words
Influenza virus vaccine adjuvanted 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 immunosuppression reduces antigen-driven lymphocyte activation and antibody production.
What to do
Vaccinate before starting steroids or at the lowest feasible dose when timing allows. Consider that protection may be incomplete and maintain other preventive measures.
