Newsweek ran an informative Q and A with one of the study authors about who should get the vaccine and when. The New York Times did a big story, too, which I thought displayed a bit of bias in the disapproving tone of its headline: Researchers Question Wide Use of HPV Vaccines. I called Maura Gillison, MD, a researcher at Johns Hopkins in Baltimore and one of the top experts on HPV, for her perspective. She said, “For those of us in the field, this study is not really new information. It is known that the HPV vaccine doesn’t have an impact on young women who have already been infected by the HPV types targeted by the vaccine (HPV6, 11, 16, and 18).” While it was possible to measure a girl’s previous exposure to HPV in the study lab, it’s not possible in a medical clinic, she says. That’s why it’s not as cost-effective to give the vaccine to women who are already sexually active. Still, she says, “only 4% of the 16- to 26-year-old women who were enrolled in the vaccine trials had evidence of exposure to [...]
