Summary
Corticosteroids may weaken the immune response to Japanese encephalitis vaccine, leaving travellers less protected. Commonly used inactivated vaccines carry no infection risk, so the issue is reduced efficacy.
What this interaction means in plain words
Japanese encephalitis virus vaccine 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 reduces vaccine-induced antibody production.
What to do
Complete the series before starting immunosuppressive steroid doses when possible, or allow adequate time before travel. Consider checking serology where available.
