The author and British medical doctor Andrew Wakefield claimed to have found a link between the measles-mumps-rubella (MMR) vaccine and an autismlike disorder.
Currently 102 (53%) of 192 WHO member states include mumps in their routine childhood vaccination programmes, mostly as the combined measles-mumps-rubella (MMR) vaccine.
The nonsense about vaccines causing autism began with a now - discredited 1998 paper by British physician Andrew Wakefield that linked the disorder to the measles-mumps-rubella vaccine.
