Personally, I think the benefits and protections offered by vaccines outweigh the potential onset of autism. I don't think vaccines cause autism, but I do think it is very possible that something in the vaccines may trigger the onset of autism in someone genetically predisposed to it. More research needs to be done on the subject as more and more children continue to be diagnose with autism. There is an excellent debate about vaccines and autism at www.opposingviews.com/questions/are-autism-and-vaccines-linked Experts from both sides weigh in and make some very thought-provoking points on the issue.
