My DD aged 14 just got a puncture wound from a screw sticking out from a cabinet. It was deep enough to ooze a little blood. I washed it under running water, with some liquid soap, and have put savlon on the wound.
I am not worried about the actual wound which is trivial, but is she likely to need a booster shot of tetanus?
She is immunosuppressed on biologic meds and azathioprine for IBD, if it's relevant.
