Rabies from aerosols
Only under exceptionally rare cases might rabies
be transmitted through the air --the environment would be a bat cave with millions of bats flying around your head.
You would not get it from being near a rabid animal. However if you work in a vet's office - I would just get the vaccines as it could save you alot of trouble in the future, God forbid if u are scratched or bitten by a suspect animal.
