Vaccination

I would really like to know ABC's thinking on this.  First, the only subject that Jenny McCarthy seems to have had an opinion on is vaccines cause autism.  I've actually spent the last half hour googling her to discover if her activism crosses into areas other than autism and came up empty handed.  So why would ABC select one issue McCarthy to co-host a show that covers a multitude of issues? And there's concern over giving Jenny McCarthy such a large platform.
