Success of the HPV Vaccine

HPV is a sexually transmitted disease that causes ovarian cancer in women. A vaccine for many variants of this virus has been out for a few years. It's shown to be quite effective at preventing infection. You might even say...

In fact, prevalence of HPV decreased 56% since 2006, among females aged 14 to 19.

This is surprising, because only about 1 in 3 girls in this age group have received the full three doses. Half of them have received at least one dose, which seems to be 82% effective.

The effectiveness of the vaccine is also boosted by something known as herd immunity.

This is good news for women, because ovarian cancer is the fifth leading cause of cancer death in women.

Not for long!
