Dr. Andrew Wakefield got caught involved in fraudulent activities and other misconduct associated with in his studies that he said showed vaccines were causing autism and lost his license.

Also I think you are mixing up intelligence and knowledge. Einstein was way more intelligent than me but I know way more about scoliosis than he did. So despite his intelligence I have more knowledge. The Vienna Report web site demonstrates this problem. That woman is probably smart but she has no grasp of the scientific facts nor does she have any training to tell good from bad work. And it shows.
The PhD trains people on how to do research and basically how not to fool yourself or others. Without that training we have solid nonsense like the Vienna Report. She is fooling herself and others like yourself. Honest people trained in research do not agree with Wakefield or other conspiracy theorists.
No everyone is not free to be selfish and benefit from herd immunity. The only reason people can even try this is because most other kids are vaccinated.Bottom line is everyone is free to believe and do what they want on this issue of medicine and the medical profession. I think modern medicine shines in the field of trauma,.....they can patch you up after a dibilitating car accident like nobody's business, and can have an asthmatic breathing like a champ with steroids, they can substantially reduce pain or make it disappear completely, if need be, and other modalities like these....all good and wonderful,......is gets more murky when the cure or prevention of an illness or disease will stop the money wheel or slow it down substantially.
You also probably don't believe Wakefield did anything wrong when we know he did. Maybe Mendelsohn will loss his medical credentials like Wakefield. He is either mistaken or lying. You pick which. There is no third option.But, I do not believe or think Dr. Robert Mendelsohn was irresponsible for writing his books,....I think he opened eyes,....and there are many, many doctors and scientists and researchers for that matter that are on the same page he was,......people that know much, much more about all these issues than I do,.....So, common sense tells me there is truth in it.......I like to look at ALL the pieces of a puzzle,.....stand back,....take them all in,....and then make my decision on a medical issue,......Usually, when I do that,....it becomes perfectly clear what to do,......or not do.......
Look I know it is hard for lay people to wade through this material. But if you don't have training to vet it then you need to rely on intellectually honest experts like those at the CDC.
