This is an old post, but I thought I'd reply as I have great concerns with the MMR. I think immunizations are important, vital. I only wish single MMR jabs were available. I'm aware of Wakefield now, though I didn't then. I really don't have an opinion one way or another.
I currently have the most darling 5 year old daughter a mom would ever hope for. She has had all of her immunizations on an alternative schedule, except the MMR. Here is why I'm concerned. Do note, given my own experience working in medicine and associations with those who work in politics, I could care less that studies suggest the MMR doesn't cause Autism. I know with my own eyes it absolutely does. It's not common, but it absolutely happens.
To those parents who have witnessed their child(ren) regress DIRECTLY after the MMR, you are not crazy. I've seen it too. I live across the pond from most of you, in the US. I worked in a school for children with autism directly after college in 2002, when I first heard about fears over the MMR. I, too, thought it was a crazy notion, that parents believed an immunization actually caused their children's autism. Then, I saw the evidence. Pictures, videos, real documentation of vibrant, very normal kids laughing, playing, speaking at a stage expected for their age group. Then, they received the MMR. Immediate regression, not within just days, within hours. Hours.
To those who have children unaffected, I know how easy it is to believe the MMR Autism link is nothing but nonsense. I disbelieved the correlation too. Talk to a mom who has evidence contrary and you very well may change your mind. I don't know what the politics are like in the UK, but in the US, just about anyone I know, and I work in medicine mind you, would laugh hysterically if one were to say they trust the CDC or the FDA. Nothing could be more laughable. I certainly can't believe a study backing them up.
My own theory is that because measles, mumps, rubella all have a potential to cause encephalitis, which can lead to brain damage, the combo shot makes a small percentage of the population susceptible to Autism. I know many of you could break apart that statement, but without going into detail, that's the consensus of what I believe. Regardless, I've seen with my own eyes evidence that calls into question the safety of the MMR.
