THE SCOPE OF HPV

• 75 to 80 percent of adults will contract HPV at some point.

• HPV annually causes 15,000 cancers in women and 7,000 cancers in men.

• Fewer than half of girls 13 to 17 have received at least one dose of the HPV vaccine. Fewer than a third have received all three doses.

• About 1 percent of boys have received the HPV vaccine.

• Vaccinating the nation's 11- and 12-year-old boys will cost almost $140 million annually.
