Summary

What this interaction means in plain words
Diphtheria and tetanus toxoids / acellular pertussis / poliovirus inactivated vaccine and Methylprednisolone 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
