Summary
Corticosteroids may blunt the antibody response to pneumococcal conjugate vaccine. Patients on steroids are at higher risk of pneumococcal disease, so vaccination remains important.
What this interaction means in plain words
Dexamethasone and Pneumococcal vaccine heptavalent 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-mediated immunosuppression reduces B- and T-cell responses to the vaccine.
What to do
Vaccinate as indicated without delaying needed steroid therapy, preferably before prolonged immunosuppression. Follow current schedules for additional doses in immunocompromised patients.
