Back in the 90s a British doctor called Andrew Wakefield was bribed by a pharmaceutical company that made separate vaccines for measles, mumps and rubella to come up with a study to discredit the combined mmr vaccine. He found a bunch of parents in an antivax society and twisted the results of a very weighted questionnaire to demonstrate a link between MMR and the 'tism. It was quickly discredited, but the damage was done. He was stripped of his medical licence after that.
