The development of cervical dysplasia (precursor to cervical cancer) and cervical cancer requires infection with one of several cancer causing subtypes of the human papilloma virus (HPV). There are over 100 subtypes of HPV, and most are not cancer causing. In the past, North American data has shown that 70% of early cervical cancers were associated with HPV subtypes 16 and/or 18. The first HPV vaccines to be approved protected against the common subtypes of HPV 16 and 18. The traditional HPV vaccination consists of 3-doses administered over a 6 month period.
