In light of recent media speculation about the new US President’s views on autism, we feel it's important to re-state that research has comprehensively found no link between vaccines and autism. Autism can have a profound effect on someone's life and people understandably have questions about its causes.

Much research has explored whether there is an association between autism and vaccines, and the results have repeatedly shown there is none. This includes a comprehensive 2014 review of all available studies in this area, using data from more than 1.25 million children. In addition, the original research linking the MMR vaccine with autism has been discredited and the author was struck off the medical register. 

We believe that no further attention or research funding should be unnecessarily directed towards examining a link that has already been comprehensively discredited. Instead, we should be focusing our efforts on improving the lives of the 700,000 autistic people in the UK and their families.

We still don't fully understand the exact causes of autism but research to date has shown it involves many complex and interacting factors, including genetics, the environment and the development of the brain.
