Curious, so found this – the mainstream medicine view of prevention rabies vx for humans. It’s a lot. Looks like it does not guarantee no infection from a diseased animal bite, but they claim it makes post-exposure treatment more effective.

This may be more useful – 2015 analysis of vaers data. It doesn’t say how many doses it represents, but says that 6% of side effects were serious. Maybe the best course would be to contact a naturopath for anything you can do pre-injection to make it less harmful, and anything to do post-injection to clear it. I’ve seen discussion of people doing things to clear different mandatory vaccines. Things like hydrating, a certain amount of vitamin C, etc.
