I am very on the fence about vaccinations. But I can tell you my son has autism, more specifically he has Aspergers Syndrome. Luckily his case is not severe but its there and its not easy. I do know he was developmentally fine until he was around 18 months then he started to not make his milestones. Coincidental ? I'm not sure. Like I said I'm on the fence. But I think it should be the parents choice. I also know one of the vaccines he received was recalled and is no longer given. There is a replacement but knowing that it was recalled in itself is scary.
