Update on vaccination against human papillomavirus (HPV).

HPV vaccine offers a new approach to preventing HPV and associated conditions. The vaccine has mainly been studied in young women, and clinical trials have supported its efficacy in preventing genital warts and cervical precancers caused by targeted HPV types. While health care experts and others endorse the use of the vaccine, they disagree on making it mandatory. For now, lawmakers would like further discussion and debate before pushing legislation to make the vaccine a legal requirement.
