(CNN) A newly released study finds that Gardasil, the vaccine prescribed to prevent cervical cancer, could have some additional benefits for women already infected with HPV.

The study shows that Gardasil reduced the reoccurrence of HPV-related diseases by 46 percent.

The Centers for Disease Control and Prevention says the human papillomavirus is the most common sexually transmitted infection.

It usually clears on its own, but can lead to genital warts and cervical cancer when it doesn’t.

Gardasil’s manufacturer, Merck, funded the study, which appears in this week’s British Medical Journal.
