Summary
Corticosteroids at immunosuppressive doses may weaken the antibody response to vaccines. This vaccine is non-live, so there is no infection risk from it, but protection may be lower. Vaccination should not usually be withheld for this reason alone.
What this interaction means in plain words
Human papillomavirus vaccine nonavalent and Methylprednisolone have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Glucocorticoid immunosuppression reduces vaccine-induced immune response.
What to do
Vaccinate on schedule where possible, ideally when steroid doses are low or after therapy ends. Consider checking the response or giving further doses if the patient is highly immunosuppressed.
