Dr Andrew Wakefield's 1998 Lancet study caused vaccination rates to plummet, resulting in a rise in measles - but the findings were later discredited.
The General Medical Council ruled he had acted "dishonestly and irresponsibly" in doing his research.
Afterwards, Dr Wakefield said the claims were "unfounded and unjust".
The GMC case did not investigate whether Dr Wakefield's findings were right or wrong, instead it was focused on the methods of research.
During the two-and-a-half years of hearings - one of the longest in the regulator's history - he was accused of a series of charges.
