Scientists dismiss evidence of MMR link with autism
By Sam Lister, Health Correspondent
SCIENTISTS have strongly rejected any suggestion that the measles, mumps and rubella vaccine, MMR, is linked to disorders such as autism.
An analysis of 31 MMR studies by the Cochrane Library, the most authoritative source of evidence-based medicine, has shown no credible grounds for claims of serious harm.
Uptake of the vaccine decreased sharply after research by Andrew Wakefield, published in The Lancet in 1998, suggested a direct causal link between autism and Crohn’s disease. The research, since discredited, resulted in the uptake falling to less than 70 per cent in some parts of Britain — far below the 95 per cent recommended by the World Health Organisation. This has been blamed for contributing to an increase in measles and mumps.
Health campaigners hope that the latest analysis, published in the Cochrane Review, will boost the MMR uptake. It supports a study published in The Lancet last year that poured scorn on the suggestion of a link between the combined vaccine and autism.
