Hello there,
Dont worry and panic so much....you can have your tetanus shot tomorow also if it is not available now....also if you want to take it urgently...you can go into any government run health center or civil hospital...i am sure medinapore to have one open at odd hours...also they will do your dressing for pin prick.
