Look at it this way earthworm.
I have 2 kids with ASD and probably more up to date knowle4dge than most 9although MN good for informed posters).
I have worked in the field.
I have a traceable family history of obvious if not DX'd people with ASD at many lvels, as well as related disorders including OCD, auto-immune, depressions, dyspraxia.
if people want me to give MMR they'd have to actively prove safety rather than a link.
We gave separate jabs: Mum lost a baby to rubella after several stillbirths, I am under no delusions about impact- on her, but equally on us as a family.
DS1 was pretty obviously born on the spectrum: no doubts about that, horrid pregnancy (hyperemesis, pre-eclampsia, early induction).
DS3 not- he regressed. He is the mroeserious. After his MMR although DH is mroe convinced of the link than I am.
I am in with kids with ASD every day one way or another and I don't see a cause. That emans I cannot write off individual causes either. I suspect any of a hundred things could have triggered dss3's ASD. Or ds1's proabbly, just it was his birth that did.
I don't know anyone in my situation who has given MMR. Most do as I have done, wlthough the lcoal measles clinic closed so mroe will be unimunised. That's the fault of the infrastructure, not them. You cannot take away the chances and then criticise people for not following them.
Every day my children's lives will be affected with ASD and regardless of what other think it is my duty to protect them in every way I can. If I can protect otehrs also so be it but that's a bonus not a primary drive.
DS4 has the same diertary isue that accompanies ASD in our family ( a casein intolerance that has caused FTT in 3 / 4 of my boys including ds4) and yet he is thriving now, no real ASD traits, good langauge. If you think I would even consider doing anything anyone has suggested might blow that you are truly having a laugh!
I ahve no idea of your background or if you knwo what it's like to have two kdis dx'd in a twelvemonth; to have your dry, chatty almost three year old go from that to non verbal and incontinent in a few weeks (he now talks and is dry again at almost 7).
I am not willing to go through that agin if there's a millionth of a per cent chance I can avoid it.
That, to me, is logical.
The GP's we see etc deny the dietary link as well; yet surely 6 people with and 5 with an asd in the wider family is not something I would ignore!
Sadly she is no longer a member of this site but anything by JimJams is worth looking up as she is one of the most intelligent women I know and scientific to an nth degree (well mroe like her nth degree I think- if you include related PhD's etc).
But for me I simply have to do my best for my boys.
