once every 2 years or so
its been a long time. Like 3 years but possibly more. I also have never gotten vaccinations, except the ones they make you get to enroll in elementary school, and don't go to the doctor. I believe going to the doctor an excessive amount over every little thing can really fuck your immune system in the long run. Better to let colds and things run their course.Even if I was dying I think I'd still refuse to go to the doctor. Doctor offices are literal Hell.
