Britain's general medical council last week disciplined the paper's lead author, Andrew Wakefield, saying he acted "dishonestly and irresponsibly" and with callous disregard to children.
Most of the accusations against Wakefield involve ethical codes, including paying kids at his child's birthday party for blood samples.
Wakefield said he has no regrets for the research, which contributed to some parents questioning whether or not to get their kids vaccinated.
Newer studies have since refuted Wakefield's findings, saying the MMR vaccine is safe.
