All of the reported cases have been looked at by an independent body - the Medicines Control Agency/CSM is independent and collects data on adverse reactions to all drugs and reviews all of them, in detail, on a weekly basis. Anything that is not clear is followed up with the reporting doctor for further information.
An MMR Working Party was set up (years ago!) to look at all Andrew Wakefield's cases and others that had been sent in separately and no link was found - this has been done over and over again.
The adverse reactions to, and safety of, MMR are reviewed in the same way that the safety of every other drug on the market is reviewed so what I don't understand is why everyone is happy to accept the CSMs judgement on the safety of all the other drugs that they and their children are exposed to but not this one?
It's a difficult issue I know and I've had to make the decision myself for my own children (who have all had the MMR) but I suppose I'm in the fortunate position of having worked closely with those involved at the MCA where I was head of the Drug Alert Unit in the Pharmacovigilance Unit for 5 years and sat on CSM meetings.
Just to clarify as well, CSM members who have 'an interest' in a pharma company that markets a drug being discussed in a meeting, has to declare that interest and leave the room. They take no part in any decision being made.
