Talking about denialism: I'm going to cut and paste a post by someone else because it basically says it all:
The naysayers;
Fail to address that the MMR originally introduced to the UK was known to be unsafe. The vaccine was introduced in the UK in the same month it was withdrawn in Canada.
Fail to address that it is thereby highly unscientific to declare the MMR vaccine to have a sound safety record (although the DoH does so regularly).
Fail to address that they have yet to produce a solid, unflawed study which gets anywhere near even examining Dr Wakefield's findings, let alone challenging them.
Fail to address the fact that the disease documented in children with regressive autism who present gastrointestinal symptoms following vaccination with MMR is extremely similar to conditions such as CDD (childhood disintegrative disorder) - a condition which has been associated with measles encephalitis following wild infection.
Fail to address the documented evidence that the risk for IBD is elevated following atypical infection with mumps, measles and or rubella with close temporal relationship.
Fail to address the documented evidence of highly elevated measles antibodies in affected children - levels which are consistent with presentation of measles encephalitis.
Fail to address that fact that the MMR vaccine is neither necessary nor ethical.
Fail to address that regressive autsim with gastrointestinal symptoms has been consistently shown to be a condition which affects the gut, the brain and the immune system. (i.e. this condition has been consistenly shown not to be psychiatric.)
Fail to address that the incidence of the above syndrome is increasing (i.e. it cannot be a purely genetic phenomenon but must be one which has an environmental element).
Fail to provide any evidenced alternative explanation for what has happened to the children considered to have reacted badly to MMR vaccination (indeed fail to even examine the children in question).
Fail to address the fact that declaring that they know what has not happened to these children (whom they have not examined) whilst remaining entirely ignorant of what has happened to them, is a ridiculous and unscientific position.
Fail to address that the only explanation they have provided on the entire issue can be summed up in one unscientific word - coincidence.
Denialism much?
