Summary
Corticosteroids may reduce the antibody response to inactivated trivalent influenza vaccine, especially at higher doses. Vaccination is still advised because the vaccine is not live.
What this interaction means in plain words
Influenza virus vaccine trivalent 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
Glucocorticoid immunosuppression dampens B- and T-cell responses to vaccine antigens.
What to do
Vaccinate annually despite steroid therapy, ideally when the dose is lowest. Do not rely on vaccination alone for protection in heavily immunosuppressed patients.
What to ask your pharmacist
