If rabies is virtually 100% fatal and humans have a vaccine, why is it not common practice to give every human a rabies vaccine?

The rabies vaccine has a pretty high rate of side effects, and for most people it's really not needed.  The only people who are vaccinated as a preventive measure are veterinarians, spelunkers (risk of rabid bats), or people traveling to areas where rabies is a problem.  If you don't have an imminent need for the vaccine, there's no point in administering it, since the overwhelming majority of  people will never need it. And it's 100 effective when administered soon after a bite anyway.
