FIRST find out what immigrant brought it in
SECOND then go back to giving it as a SINGLE shot.
Absolutely! Having single shots is essential for vaxxed-unvaxxed studies. May I suggest stand alone tetanus?
May I suggest not getting a Tetanus shot at all ONLY if you need one? Like after you need it cause you can. Haven't ever had one myself.
I’m not saying everyone needs one; just saying assess personal your risk - benefit.
