I stopped getting vaccines after getting sick too. After my second HepB shot I was sick with flu-like symptoms for two weeks and developed a phobia of anything sharp. Now whenever I need my blood tested I have an absolute panic attack. My dad developed both the hyperactive and innattentive subtypes of ADHD after getting his first shots, so he never had any shots for the rest of his life. My stepmom always laughs because she got all of her vaccinations and still got mumps, my dad didn't get any vaccinations and barely gets a cold.
