Deffinantly do research (that way if you still do decide to vaccinate you have backup)
but there is no direct proof with vaccines causeing autism, and what people thought might contribute to it (i beleive it was small traces of murcury, but I could be wrong) they have all but gotten rid of in almost every vaccine
like dannzibelle said, its your kid not theirs you do what you feel is right, dont take their word on the matter but dont just disreguard their word either (thats where research comes in)
also like kia said bing a chiropractor has nothing to do with beleiveing or not in medicine, ive had chiropractors who have specifically sent me to different doctors to get medicine for some things
