My attitude about Jenny McCarthy is well-documented here. She is a leading spokesperson for the antivaccination antiscientific movement. These are people who think vaccines cause autism, despite no evidence at all showing this to be the case, and a tsunami of evidence clearly showing there is no relation at all.
I will have more to say about Ms. McCarthy soon -- oh, do I -- but for now I want to alert you to a new website called Stop Jenny McCarthy. It has information about her claims, and links to where you can find more and better information. It's only just started, but I imagine it will have plenty more info as time goes by. The people who put it together are skeptics themselves, and, like me, feel the need to alert the public about known cases of uncritical thinking, especially when it represents a major health risk.
