The National Autistic Society (NAS) has launched an open letter in response to his lies and is calling for the public to join it in the fight for the truth. This comes after Trump made the baseless claims that taking paracetamol and vaccines cause autism. Trump’s announcement is the latest in a relentless rise in baseless and offensive claims about autism. The NAS said it is important to be very clear - paracetamol does not cause autism and vaccines do not cause autism. These lies about autism are having a huge impact on the lives of autistic people and their families.
