Wash it good and keep an eye on it. If it starts to swell soak it in warm sea salt, that will draw the infection out.

I got stabbed in the thumb by a Vet that was trying to Euthinize a cat, I was 6 months pregnant, thankfully the syringe was still full, it was not enough to harm a human, just a 6 lb cat. So that was fun! I never had an infection or anything bad happen.
