The doctor that started the autism-vaccine connection has been stripped of his medical license by the UK after a 2 and half year investigation. In January, the General Medical Council ruled that Andrew Wakefield had acted in an unethical manner in regards to his 1998 paper claiming that the MMR vaccine causes autism (30 counts of unethical behavior ranging from paying the kids for blood samples without parental consent to conflicting financial interests and scientific fraud). Also early this year, the paper was officially retracted by The Lancet (finally) - the results have not been duplicated by other researchers despite more than a decade and and tons of money. Time and money that could've been spent finding real information out about autism.
In addition, the vaccine scare prompted decreased vaccination rates that have resulted in resurges in Measles and whooping cough, two very unpleasant and potentially fatal diseases that were nearly wiped out in the U.S. by the 1990s. Measles kills nearly 200,000 children a year worldwide. And this guy told parents to boycott the only thing that can protect them from this highly contagious viral infection for no reason except his own professional and financial gain.
Yeah, I don't have anything nice to say about this guy, so I'll just leave you with those facts. The BBC covered other details, including two colleagues who were also found guilty of professional misconduct in the case.
