Yet again, the argument that Mary and some of the parents of children with ASD have built is based on a fallacy. This time it is known as Post Hoc Ergo Propter Hoc, meaning after this therefore because of this. Amy must redress this as well by thinking of an absurd example.
Well, correlation does not always equal causation. This means that just because they happen one after another, it does not mean that the first event caused the second.
It's like saying that your child getting their first molars causes them to develop Autism.
That's absurd! Everyone gets their first molars and not everyone has Autism.
Exactly! The vast majority of Canadian children get their vaccinations, about 89%, but only about 1% are diagnosed with Autism. So there are a large amount of people who got the vaccine and do not have Autism.
Just because children who are diagnosed with Autism usually develop their first molars right before getting diagnosed does not mean that they developed Autism along with their molars. Similarly, children who receive vaccinations right before getting diagnosed do not develop Autism because of the vaccines.
Well, of course there is the chance that the child would not have Autism, whether you vaccinate the child or not.
But some parents choose not to vaccinate their children and then they don't develop Autism.
Think of it this way: If vaccines caused Autism, then more than 1% of the Canadian population would be diagnosed with Autism considering it is a highly vaccinated population.
