Rabies Vaccine

I have an appointment for my five-year-old cat tomorrow for a general checkup. I just saw a video of a veterinarian (Dr. John Robb) speaking about how dangerous vaccines are to our pets. He said one rabies shot during their lifetime is enough. He cites many articles written about this issue. I’m not getting my cat vaccinated if there’s even an ounce of truth to this. Thoughts?
