Vaccines are effective in preventing disease with almost little to no disadvantages. By vaccinating your brats, you also provide what's called "herd immunity," meaning that vaccinating a majority of the population protects the few people who cannot get vaccinated for medical reasons. ALSO VACCINES DO NOT CAUSE AUTISM. Not only is that factually wrong, it's incredibly insulting to the community of people on the autism spectrum. I understand that it is difficult to live with autism, but would people rather their children contract these horrible, preventable, medical-school-textbook-awful diseases, than have autism?
