HPV vaccine not linked to riskier sex, STIs: study

University of Miami pediatrician Judith L. Schaechter gives an HPV vaccination to a 13-year-old girl at the Miller School of Medicine on September 21, 2011 in MiamiDespite concerns among some parents, the vaccine against human papillomavirus (HPV) does not cause riskier behavior in teens, nor does it raise rates of sexually transmitted infections, US researchers said Monday. The findings by a team of experts at Harvard Medical School and the University of Southern California are published in JAMA Internal Medicine, a journal of the American Medical Association. Health authorities recommend the vaccine for pre-teen and teenage boys and girls as a way to prevent HPV, which can go undetected and lead to cancers of the cervix, anus, penis, mouth and throat. Vaccination rates have been slowly rising in the years since 2006, when the vaccine was introduced.
