For those who support a link between MMR and ASD - do all affected children have noticeable symptoms prior to vaccination?

[controversialquestion]

I know there have been many thread on this and don't want to provoke another general debate, but can I alk a question to those of you who support the argument that there is a link between MMR and autism? The bulk of opinion in support of the link seems to suggest that the MMR acts as a trigger for genetically susceptible individuals rahter than actually "causes" MMR. In your experiences have all children so affected experienced the "markers" that some people have identified - eg. bad reaction to previous vaccines, strong famiy history of allergy, gut problems, family history of ASD? Does anyone know of a child without these risk factors who they believe contracted ASD as a result of MMR?

I can safely say that ds1 had no markers.

None of my others have had the mmr, I could not take that risk.

Thanks, Kittywise

DS3 has a brother with asd but seemed clarer himself

dd1 is being tested for asd atm, and she showed loads of "traits" before she had mmr tbh. DD2 has had the mmr.

Thanks for these responses

ds had several markers...allergy history, gut disorder, reactions to other immunisations. He did not get the MMR and has just been diagosed with mild Aspergers...no way of knowing if this would have been worse for him had he had the injection.

Thanks very much for your answers
