When Jenny McCarthy was announced as a host of The View yesterday, Seth Mnookin published a 5,000 word chapter of his upcoming book about vaccine deniers on his blog. This chapter, which is broken up into four blog posts, is the most comprehensive history of McCarthy's connection to vaccine truthers I've ever seen.

Part one explains how McCarthy became famous.

Part two is about her Oprah interview and the point when McCarthy became famous for her junk science.

Part three is about how she legitimized fringe anti-science groups.

And part four is about the pain and heartbreak McCarthy has already caused.

I suggest you go read the whole thing.
