Cotes,
'The subject is a little more complicated than "Andrew Wakefield was a con artist and so we now know no vaccines have ever caused autism and they never will".'
Well, yes. There's loads and loads of research which has been done which shows there is no link between MMR and ASD:
adc.bmj.com/content/93/10/832.short
"Results: No difference was found between cases and controls for measles antibody response. There was no doseresponse relationship between autism symptoms and antibody concentrations. Measles virus nucleic acid was amplified by reverse transcriptase-PCR in peripheral blood mononuclear cells from one patient with autism and two typically developing children. There was no evidence of a differential response to measles virus or the measles component of the MMR in children with ASD, with or without regression, and controls who had either one or two doses of MMR. Only one child from the control group had clinical symptoms of possible enterocolitis."

"INTERPRETATION. There is no evidence of measles virus persistence in the peripheral blood mononuclear cells of children with autism spectrum disorder."

"This study failed to substantiate reports of the persistence of measles virus in autistic children with development regression. ."

"This study provides strong evidence against association of autism with persistent MV RNA in the GI tract or MMR exposure."

"No significant differences in antibody titers to measles, mumps, and rubella viruses and diphtheria toxoid were found among the four groups. Additionally, there were no significant differences between the four groups for total immunoglobulin (Ig)G or IgM"
That's just the first few papers, there are more. Scientists have attempted to replicate Wakefield's findings, and they haven't been able to. And yes, Wakefield was a fraud, his study itself was fraudulent, as is described in the BMJ:
'In an editorial, Dr Godlee, together with deputy BMJ editor Jane Smith, and leading paediatrician and associate BMJ editor Harvey Marcovitch, conclude that there is no doubt that it was Wakefield who perpetrated this fraud. They say: A great deal of thought and effort must have gone into drafting the paper to achieve the results he wanted: the discrepancies all led in one direction; misreporting was gross.
There is no link between the MMR and ASD. Studies have looked for the link and not found it.
Cheers,
