High school! =O
Teachers gave us [seniors] the impression that our vaccinations were required for college admission (or just for the good of seniors who would go to college), but I don't know. I don't think that my university requires any vaccinations now, but that may not have been the case three years ago; I can't remember. I only remember that I had to provide proof of my vaccinations to be eligible for graduation in high school.
I didn't get my third hepatitis B shot. By the time I was scheduled to get it, my phobia of syringes had developed. XP
