The Human Papillomavirus (HPV) has become so widespread that there are doctors who compare it to the common cold. While some forms cause cervical cancer, others result in genital warts. According to the American Cancer Society:

In the United States, over 6 million people (men and women) get an HPV infection every year. Almost half of the infections are in people between 15 and 25 years of age. About one-half to three-fourths of the people who have ever had sex will have HPV at some time in their life.

To see what the ACS recommends,

Though the only way to prevent HPV is abstinence, a vaccine prevents some forms that cause cervical cancer. So, the ACS recommends that to be most effective, the vaccine should be given to females before they are sexually active and in a series of 3 doses within 6 months starting with girls as young as nine-years-old.

Would you let your girl get the vaccine?
