Due to his stance on vaccines and autism, Paul has been on the receiving end of an enormous amount of grief and quite a bit of misinformation has been published about him. Recently, though, two items have appeared that help to counter that misinformation and I wanted to point you to those items so that you can see the primary resources.
Some of Paul's detractors call him "Dr. Proffit," because he helped invent a vaccine that was then purchased by a pharmaceutical company. Incorrect reports say that Paul received tens of million of dollars and that he helped ensure that the vaccine he helped invent became a part of the CDC recommended schedule of vaccines. This post, from the Countering Age of Autism blog, provides the correct information.
Next, well, there's this little magazine called WIRED, and they just published a cover story(!) about Paul and his efforts. You can read it online at http://www.wired.com/magazine/2009/10/ff_waronscience.
