I think at the moment they only give them to people who are in occupational risk. For example, the vets and vet techs i worked with are all vaccinated, and so am I due to a possible (at the time) exposure. The dog that bit me was showing possible signs of rabies, but when he died, no virus was found in his neural tissue. Because the effective window for taking the vaccine is 10 days, I didn't wait until the dog died (owners refused to put the dog down, against the law to euthanize without permission) to get my rounds. It was an extremely minor wound, but even the tiniest nick transmits the virus as long as saliva makes contact. Even though the poor dog turned out to be negative, he ended up dying... And now I'm immune for a few years.

...have not had one dog or cat I've helped vaccinate come back with rabies. The only problem I have with this is that vaccines are extremely species specific... So unless they have a raccoon, possum, fruit bat, cat dog universal mammal edible protect-all, it seems like a waste of money.... Then theres the issues of making sure the animals eat the dang thing...Must look this up!
