The document discusses HPV (human papillomavirus), which is a common virus that can cause cervical cancer. HPV is transmitted through sexual contact and often has no symptoms. Cervical cancer may result from HPV infection but can be prevented through annual screening and the HPV vaccine. The HPV vaccine, Gardasil, protects against the types of HPV that cause most cervical cancers. It is recommended for females ages 11-12 and can be given to females up to age 26. While the vaccine effectively prevents cervical cancer, some barriers to its use include costs, concerns over side effects, and lack of information. Efforts are being made to increase vaccination rates and expand the vaccine's use internationally.
