Are inmates allowed shots like tetanus or other vaccines at the prisons?

My son is an inmate at the Roger State Prison and he was bitten by a mouse which had gotten in the prison at some point. He went to medical to get a shot just in case the mouse had a disease. the tetanus shot is usually given. They being the nurse or if seen by a doctor one would receive a shot. Are they not allowed shots of that sort at the prisons? Thank you
