Here is another article about vaccines and the anti-vaccine movement. I wrote a little bit about this topic here and about the primary mercury arguments here and here. My favorite skeptic and astronomer, Phil Plait, has posted a link to what he describes as:

From the vacuous pseudoscientific nonsense of antivax spokeswoman Jenny McCarthy, to the out-and-out evillness of Andrew Wakefield, the father of the modern movement whose conflicts of interest when it comes to vaccines are simply breathtaking, Dr. Gorskis post is nothing short of what should be The Link, the one you send to all parents who question whether they should vaccinate their children or not. Everything you need is there, with the history, quotations, false claims, and everything else about the antivax movement, including links to more information.
