The item he mentions, that I told him he was wrong about, was from late September. In the course of talking out the Perry / Bachmann / HPV vaccine kerfuffle, he was radically underestimating the prevalance of HPV; something on the order of a quarter of all American women get exposed at some point, and the strains in question are responsible for a large proportion of all cases of cervical cancer. The public-health case in favor of mass-distributing the vaccine, and administering it before sexual debut, is quite solid. It's been laid out in Slate, in the DoubleX blog. I had to scold him for not reading his own employees' work thoroughly enough. :-)
