Summary
The polysaccharide vaccine is non-live, so it is safe to give, but immunosuppressive prednisone doses may reduce the antibody response. Protection may be blunted in patients who most need it.
What this interaction means in plain words
Pneumococcal vaccine polyvalent and Prednisone 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 suppression of lymphocyte function reduces vaccine-induced antibody production.
What to do
Do not withhold the vaccine; give it before starting steroids if feasible. Follow local guidance on revaccination for immunocompromised patients.
What to ask your pharmacist
