HPV vaccine reduces infections in teen girls by half: Study
A study published in the Journal of Infectious Diseases shows that the HPV vaccine has reduced the infection rate in teenage girls by more than half, despite low vaccine uptake. The study, published in June, is titled “Reduction in Human Papillomavirus (HPV) Prevalence Among Young Women Following HPV Vaccine Introduction in the United States, National Health and Nutrition Examination Surveys, 2003–2010.”
Study authors analyzed HPV prevalence data from the vaccine era (2007 to 2010), and the prevaccine era (2003 to 2006) and determined that among females aged 14 to 19 years, the vaccine-type HPV prevalence (HPV-6, -11, -16, or -18) decreased from 11.5% in 2003 to 2006 to 5.1% in 2007 to 2010, a decline of 56%. Among other age groups, the prevalence did not differ significantly between the two time periods (P > .05). The vaccine effectiveness of at least one dose was 82.
