- 2. Who is Andrew Wakefield? Born 1956 Former British surgeon and researcher St Mary’s Medical School London Qualified 1981 Became fellow of the Royal College of surgeons in 1985 Continued studies at University of Toronto became a transplant surgeon specializing in small intestine transplantation Became senior lecturer and honorary consultant in gastroentology Royal Free Hospital School of Medicine
- 3. While researching Chron’s disease, approached by Rosemary Kessick (1995) Parent of autistic son seeking help with his bowel problems and Autism Kessick runs Allergy Induced Autism Focuses on effects of diet on autistic children’s behavior Lead author of study published in 1998: Wakefield AJ, Murch SH, Anthony A, et al. “Ileal-lymphoid-nodular hyperplasia, non-specific colitis, and pervasive developmental disorder in children”. Lancet 351 (9103): 637–41 (1998).
- 4. His Claims Parents of 8 of the 12 participants made a temporal link to their child’s behavioral abnormalities with the administration of the MMR vaccine "We did not prove an association between measles, mumps, and rubella vaccine and the syndrome described,“ In his 1998 paper published in The Lancet However in a later press conference, Wakefield suggested that parents space out three separate vaccines instead of the multiple MMR vaccine administered in a single dose Claimed Mesles infections obtained from vaccine causes Autism. Twenty Twenty Interview, Feb 4, 1998: on the MMR vaccine • INTERVIEWER: …do the advantages of continuing with the vaccines outweigh the disadvantages of a problem developing if you, if you continue to have them? • DR ANDREW WAKEFIELD: Well I think it’s a very complex question. Certainly if you continue, as I would recommend to use the single vaccine, you do not incur a greater risk of those diseases in the children, so that you do not lose the benefits of vaccination if you space them over time. • INTERVIEWER: (CUTS) So even measles? • DR ANDREW WAKEFIELD: Well as yet we don’t know, but there is no doubt that if you give three viruses together, three live viruses, then you potentially increase the risk of an adverse event occurring, particularly when one of those viruses influences the immune system in the way that measles does. And it may be, and studies will show this or not, that giving the measles on its own reduces the risk of this particular syndrome developing.

- 7. Autism What is autism? According to the NIH National Institute for Neurological Disorders and Stroke: “Autism spectrum disorder (ASD) is a range of complex neurodevelopment disorders, characterized by social impairments, communication difficulties, and restricted, repetitive, and stereotyped patterns of behavior.” http://www.ninds.nih.gov/disorders/autism/detail_autism.htm
- 8. How is autism diagnosed? (Taken from NIH National Institute for Neurological Disorders and Stroke) ASD varies widely in severity and symptoms and may go unrecognized, especially in mildly affected children or when it is masked by more debilitating handicaps. Very early indicators that require evaluation by an expert include: • no babbling or pointing by age 1 • no single words by 16 months or two-word phrases by age 2 • no response to name • loss of language or social skills • poor eye contact • excessive lining up of toys or objects • no smiling or social responsiveness. Later indicators include: • impaired ability to make friends with peers • impaired ability to initiate or sustain a conversation with others • absence or impairment of imaginative and social play • stereotyped, repetitive, or unusual use of language • restricted patterns of interest that are abnormal in intensity or focus • preoccupation with certain objects or subjects • inflexible adherence to specific routines or rituals. http://www.ninds.nih.gov/disorders/autism/detail_autism.htm

Thimerosal!! www.drugs.com Ethyl Organomercury compound, (was) used as preservative in vaccines In one 1928 incident, 12 of 21 children vaccinated for Diptheria with a vaccine without any preservative died from a Staph infection. (FDA) Doesn’t reduce vaccine effectiveness like current (at the time) preservatives Studies show it is safer than inorganic or methyl organomercury US began removing it from vaccines as a precaution in 1999 Removed from all childhood vaccines except influenza by 2001 Currently only found in Flu vaccine (trace amounts) Appears to be cleared by body after some time (weeks) Clarkson TW, Magos L (2006).

- 26. Actually, Wakefield’s paper was retracted by the Lancet The Lancet, Volume 375, Issue 9713, Page 445, 6 February 2010 (retraction) Controversy arose as soon as his study was published Increased when the UK made no plans or efforts to offer a single vaccine alternative Wakefield left the Royal Free Hospital blaming the unpopularity of his results in 2001 Continued clinical research in US with controversial researcher Jeff Bradstreet
- 27. Allegations of misconduct presented in the Sunday Times (London) or Channel 4 by investigator Brian Deer Date reported: Feb 2004: Some of parents in study were recruited by a UK lawyer preparing a lawsuit against the MMR manufacturers 24 hrs prior to release of Sunday Times report: Lancet retracts an interpretation in the paper and state that Wakefield’s research is “fatally flawed.” 10 of 12 coauthors involved in retraction November 2004: Prior to paper’s release Wakefield filed patent application for a single measles virus. Wakefield files Libel charges against “everyone.” but has his actions frozen until General Medical Council proceedings against him conclude. He was forced to pursue charges or drop them. November 2005: Channel 4 lawyers submit pleadings to the court:
- 28. (i) Had dishonestly and irresponsibly spread fear that the MMR vaccine might cause autism in some children, even though he knew that his own laboratory's tests dramatically contradicted his claims and he knew or ought to have known that there was absolutely no scientific basis at all for his belief that MMR should be broken up into single vaccines. (ii) In spreading such fear, also acted dishonestly and irresponsibly, by repeatedly failing to disclose conflicts of interest and/or material information, including his association with contemplated litigation against the manufacturers of MMR and his application for a patent for a vaccine for measles which, if effective, and if the MMR vaccine had been undermined and/or withdrawn on safety grounds, would have been commercially very valuable. (iii) Caused medical colleagues serious unease by carrying out research tests on vulnerable children outside the terms or in breach of the permission given by an ethics committee, in particular by subjecting those children to highly invasive and sometimes distressing clinical procedures and thereby abusing them. (iv) Has been unremittingly evasive and dishonest in an effort to cover up his wrong-doing.
- 29. Proceedings continued for two years until: Reported December 2006: A figure from the Legal Services Commission showed that Wakefield received £435,643 from lawyers responsible for MMR lawsuit (previously undisclosed), payments began two years prior to paper’s release Within ten days Wakefield dropped his libel charges and was forced to pay Channel 4’s legal fees UK GMC charged Wakefield with serious professional misconduct, including dishonesty, hearings began 2007 January 28, 2010 Wakefield found guilty of all charges Data fixing, caused life-threatening complications in one participant, improper recruitment of participants, invasive procedures performed without proper approval and contrary to participants interests, etc…… the list goes on
