Posieparker, you mention that you have read stuff by Brian Deer and Michael Fitzpatrick. Neither of these two can be considered reliable sources due to their links with the pharmaceutical industry.
Fitzpatrick is on the board of trustees of the Sense About Science lobby group which names the Association of the British Pharmaceutical Industry (ABPI), GlaxoSmithKline, the biopharmaceutical companies AstraZeneca plc, Pfizer plc and Oxford GlycoSciences plc among its many funding sources. Spikedonline which Fitzpatrick is also part of is a similar organisation. Both of these lobbies have a political and economic agenda.
Brian Deer's role in the smear campaign against Dr Wakefield is mentioned in the following link;
Deer is not the only one to be up to no good
"The Sunday Times' freelancer (Deer) was assisted in his efforts with free advice and assistance from the Association of British Pharmaceutical Industry funded and controlled company Medico Legal Investigations Limited
Medico Legal Investigations Limited speciality was in getting medical doctors on charges before the General Medical Council
so we know that before a single word was published by The Sunday Times, it was already being planned with the involvement of interested parties that Wakefield and colleagues were to be taken before the GMC
Another free of charge helper to Sunday Times journalist Deer was Glaxo Wellcome funded Fellow and active British Medical Association member, Dr Evan Harris MP.
Harris has advised and assisted Deer up to the present day, including attending the Wakefield GMC hearings with Deer.
The Sunday Times journalist, Deer, was also assisted by The Royal Free's Strategic Health Authority which passed Deer confidential documents 'in the spirit of openness' and including documents relating to the confidential medical treatment of the MMR child litigants
the SHA at first denied providing documents until it was pointed out the fact was disclosed by Dr Evan Harris MP, in Parliament on 15th March 2004"
IIRC journalists, unlike scientits, are not required to declare any conflicts of interest.
