Morbidity and Mortality Weekly Report (MMWR) Recommendations and Report
http://www.cdc.gov/mmwr/preview/mmwrhtml/rr5602a1.htm

A detailed MMWR report (updated March 23, 2007) providing recommendations on the use of the quadrivalent vaccine against human papillomavirus (HPV) for HPV types 6, 11, 16, and 18, for the prevention of cervical cancer, cervical cancer precursors and anogenital warts. The recommendations were developed by CDC's Advisory Committee on Immunization Practices. The goal of this report is to provide recommendations on the quadrivalent HPV vaccine for clinicians and health care providers. The report outlined the epidemiology of HPV in the United States, enlisted recommendations for HPV vaccination, and described the characteristics of quadrivalent HPV vaccine.

Centres of Disease Control and Prevention (CDC)

Besides the MMWR report, CDC has also put up several webpages on HPV vaccine. An online lecture, covering epidemiology of Human Papillomavirus, cervical cancer in the United States, efficacy of HPV Vaccine and recommendations, is available at http://www.cdc.gov/nip/ed/ciinc/hpv.htm. A webpage on HPV Vaccine Questions and Answers for the public is available at http://www.cdc.gov/std/HPV/STDFact-HPV-vaccine.htm and an information sheet for healthcare providers at http://www.cdc.gov/std/HPV/hpv-vacc-hcp-3-pages-hi-res.pdf.

This new vaccine for young women and girls protects against infection by certain strains of human papillomavirus (HPV) has obtained approval of the Food and Drug Administration (FDA). The education website of the foundation (http://www.kaiseredu.org) also covers information on the basics of HPV and cervical cancer, the HPV Vaccine, its implementation and costs, public acceptability and discussion questions.
