An investigation by journalist Brian Deer found that Wakefield had multiple undeclared conflicts of interest,[1][2] had manipulated evidence,[3] and had broken other ethical codes. The Lancet paper was partially retracted in 2004 and fully retracted in 2010, when Lancet's editor-in-chief Richard Horton described it as "utterly false" and said that the journal had been deceived.[33] Wakefield was found guilty by the General Medical Council of serious professional misconduct in May 2010 and was struck off the Medical Register, meaning he could no longer practise as a doctor in the UK.[34] In 2011, Deer provided further information on Wakefield's improper research practices to the British Medical Journal, which in a signed editorial described the original paper as fraudulent.[35][36] The scientific consensus is that there is no link between the MMR vaccine and autism and that the vaccine's benefits greatly outweigh its risks.
