Most MMR studies are meaningless, investigation claims
A massive review of the evidence on the safety of the measles, mumps and rubella (MMR) vaccine has concluded that most studies to date have been meaningless, and that more research into the vaccine's long-term effects is needed. ...
The review's author, Dr Thomas Jefferson, criticised the lack of clear design and reporting criteria for vaccine safety studies and called urgently for guidelines.
'In most of the studies we assessed, it was almost impossible to ascertain what had actually been done,' he said. 'The results were certainly deficient. We don't know whether the research was too.'
The Journal of the AMA just published my letter criticizing a an article about vaccine web sites. I maintain some vaccine info links here.
