the 'evidence' behind the link between MMR and autism was only given credit because of the 'expert' who wrote the paper. the fact that his research showed a very small sample and that this was therefore non-transferable to the general population didn't get questioned for some time. there is no significant link between the vaccine, nor is there any evidence that they are linked. if you would like more information look in the department of health guidelines or NICE (national institute of clinical evidence) which are both available online. also refer to the british national formulary (bnf) as this also has plenty of information. bam
