In June 2006, the Food and Drug Administration approved a vaccine that protects against exposure to certain strains of the human papilloma virus (HPV), a sexually transmitted virus that can cause cervical cancer and genital warts. In order to give the greatest protection, the Centers for Disease Control and Prevention's Advisory Committee on Immunization Practices recommends that girls be inoculated before they become sexually active. Some states require and others are considering requiring that 11- and 12-year-old girls be vaccinated in order to attend school, something that has set off a maelstrom of protest from parents.

In order to learn more about the vaccine, reporter Laurie Udesky talked to Dr. Dean Blumberg, a pediatric infectious disease specialist at University of California at Davis Medical Center. Blumberg describes the studies that led up to the vaccine approval, why HPV is so easy to contract, and exactly what the vaccine protects against.
