Why do so many people believe vaccines are the main cause for autism and other health issues?

So many people think they know everything and claim only children who have been vaccinated get autism yet my nephew who was never vaccinated was diagnosed with autism and he is also non verbal. Yet when you tell people this they call you are liar. If you were to check the medical history of my nephew you would see he has never been vaccinated.
