I work in a vet clinic, and so i'm exposed to the rabies vaccine as well as other vaccines, well of course not all of it always gets in the animal and what not. If it enters the air, am I at risk of contracting it?
Since you work in an environment where you could be potentially exposed to the rabies virus, I would highly recommend getting vaccinated. I think your instincts are pushing you in that direction as well...I would trust them :)
