Did your son have stitches? Most people are going to tell you that you should have done the immunoglobin. We were told that the tetanus vax will work if within 72 hours and they were not open to immunoglobin. I'm surprised based on our experience that the doctor mentioned it let alone recommended it (?). It does have blood product I think so that would have been the downside in my mind and why I didn't push more myself. I didn't want my son to get blood products.
I'm also surprised they did DT at 22 months. My son is six and got DPT. We were told you could only do DPT until I think it was seven. So hmmm....maybe I misunderstood the whole thing.
I think, based on the research I did with my son, that the DT should be ok.
As far as infection did the doctor/ER give you a sheet or information? Redness increasing, pain increasing, swelling increasing, any puss, any fever of course, emergency type red streaks--any of those would concern me re: infection. I would put bactroban cream on that if it was prescribed. It's effective against even resistant staph and is a topical antibiotic rather than oral. You could do an over the counter antibiotic cream like polysporin though it won't fight staph which would be the biggest concern in terms of serious infection. I would be less concerned about that if you didn't visit the hospital/ER.
