A vaccine developed to prevent infection with human papillomaviruses (HPV), the cause of cervical cancer, was found to be ineffective for treating women with pre-existing HPV infections, according to a study published in the August 15, 2007, Journal of the American Medical Association (see the journal abstract).

1. What are human papillomaviruses?
Human papillomaviruses (HPVs) are a group of more than 100 related viruses. They are called papillomaviruses because certain types may cause warts, or papillomas, which are benign (noncancerous) tumors. The HPVs that cause the common warts that grow on hands and feet are different from those that cause growths in the throat or genital area. Some types of HPV are associated with certain types of cancer. These are called "high-risk," oncogenic, or carcinogenic HPVs.

Researchers from Australia have found that when administering human papillomavirus (HPV) vaccinations to women, there is also a reduction of high-grade cervical abnormalities (HGAs), which are the first warning signs of a developing cervical cancer. There is a lot more research to be done to investigate the link, but could be a major breakthrough by in essence killing two birds with one treatment stone.

The study's authors explain:

________________________________________What does the cervical cancer vaccine do?
Various strains of HPV, which spread through sexual contact, cause most cases of cervical cancer. Two cervical cancer vaccines have Food and Drug Administration (FDA) approval in the U.S. — Gardasil and Cervarix. Both vaccines can prevent most cases of cervical cancer if given before a girl or woman is exposed to the virus.
