Asperger’s? So, not autism, or is that your other daughter?
It’s a spectrum disorder. Autism can have many causes but there is no credible evidence for links to any current vaccine.
I didn’t think there was any cause identified.
No single cause.
Like many other health and personality conditions there are genetic vectors but there seems to be a large chunk of environmental ones too (before birth and in early development) but nothing reliable to link it to vaccines.
Even if there were (and there AREN’T) the risk to a child (and children in general) from the diseases vaccines protect them from is much higher than a possible environmental vector for autism. While it can be very challenging raising a child with a disorder on the autism spectrum the same is true of many more common situations. It can be rewarding too.
It’s certainly not something that can switch on in later life like schizophrenia or epilepsy so all the significant causal influences come into play in the first couple of years of life.
In the past because of the age of presentation, associated behaviors would have been written off as naughtiness or daydreaming or childhood obsessions or depending on the manifestation of the disorder brightness or slowness. It still is with some.
Autistic adults like most adults are people with some aspect of their functioning less than optimised. It’s normal to be different.
