WHO position on HPV vaccines.

The WHO Position Paper on Vaccines against Human Papillomavirus (HPV): This article presents the WHO recommendations for use of the HPV vaccine excerpted from the recently published WHO Position on HPV Vaccines. These recommendations were formulated in a multiyear collaboration involving internal and external experts in the field, culminating in production of a detailed Background paper summarizing the evidence. After a series of meetings and careful consideration of the evidence for HPV vaccine introduction, WHO's Strategic Advisory Group of Experts (SAGE) on vaccines and immunization recommended use of HPV vaccine in November 2008. WHO published a complete position paper in April 2009, which presents the WHO Position. Additional evidence including a detailed Background paper summarizing the evidence last presented to SAGE is available at http://www.who.int/immunization/documents/positionpapers/en/index.html.
